Purification of water from oil represents important task... It is known that the sources of water pollution with oil products are mining enterprises, oil depots, railway transport, gas stations and stations. Petroleum products can be in solutions in an emulsified, dissolved form and form a layer on the surface.

With an increase in the contact time from 2 hours to several days, the amount of these substances in water increases from 0.2 to 1.4 mg / l (for example, diesel fuel - from 0.2 to 0.8 mg / l). The effect of petroleum products on foam stability is complex. It has been established that the defoaming effect of hydrocarbons on foam is usually manifested when they are excessive (compared to solubility) content. If the hydrocarbon is in a dissolved state, the foam can be reasonably stable.

purpose of work- influence of dissolved hydrocarbons on foam stability; the possibility of reducing the concentration of dissolved hydrocarbons by flotation.

1. Materials and research methods

1.1. Materials We used technical gelatin, anionic surfactant sodium dodecyl sulfate (DDSNa), grade "pure", diesel fuel, technical grade sodium hydroxide, grade "chemically pure".

1.2. Study of foam stability The stability of foams containing an organic phase was determined by the following methods: a) by the height of the dynamic foam layer; b) the lifetime of a column of foam 2 cm high under the applied pressure drop. In the first case, a POR-160 generator with a height of 17.5 cm and a column diameter of 3.5 cm was used. The test solution 1 cm high (volume of liquid 3.5 cm3) was poured into the generator. Air was supplied to the column at a rate of 1 cm3 / s. The time of formation of the maximum foam column and its stability were recorded. In the second method, the foam was placed in a glass cell with a porous filter (POR-40). A reduced (compared to atmospheric) pressure was created under the filter. The time of destruction of a column of foam, 2 cm high, was recorded.The solutions for the isolation of dissolved petroleum products contained gelatin with a mass content (0.02%; 0.1%) and an anionic surfactant sodium dodecyl sulfate (DDSNa) with a concentration of 10-3 mol / l and 210 -3 mol / l. Diesel fuel with a density of 0.788 g / ml was added to the solutions.

1.3. Determination of the content of petroleum products by the fluorimetric method The concentration of dissolved diesel fuel in the source water and in the water after its purification was determined by the fluorimetric method. Dissolved petroleum products (OP) were extracted with hexane. To build the calibration, a standard sample of a solution of petroleum products in hexane (nominal mass content 1 mg / ml) was used.

2. RESULTS AND DISCUSSION In this work, a solution of an anionic surfactant — sodium dodecyl sulfate — and gelatin additives of various concentrations are used to separate diesel fuel from water. The study of the surface properties of adsorption layers of gelatin with surfactant additives at the air-solution interface and the effect of surfactants on the properties of gelatin in the volume of the aqueous phase and at the interface with air have been studied earlier. It is known that the maximum foaming capacity of gelatin lies at the isoelectric point (pH = 4.8-4.9). Foam from 0.1% solutions of pure gelatin (without surfactant additives) is destroyed under the influence of even small (1-2 kPa) pressure drops. It is shown that the stability of a foam containing gelatin and surfactants depends on the pH value (in acidic media (pH 4), the layer height does not exceed 5 mm). The most stable foam from a solution of 10-3 mol / L DDSNa + 0.008% gelatin was obtained at pH = 6.62. Sustainability dispersed system at the specified pH value, it correlates with the maximum decrease in interfacial energy = 1 - 2, where 1 is the surface tension at the solution-air interface; 2 - surface tension at the interface between an aqueous solution and diesel fuel (table).

The stability of foams without diesel fuel and with its addition has been studied. At a flow rate of 1 ml / s on the POR-160 generator from an aqueous solution of the composition

- & nbsp– & nbsp–

Within 11 minutes, the foam column with continuous air passage was 18 cm. No breakdown was observed in the volume. Similarly, the stability of the dispersed system changed in the presence of diesel fuel (with the addition of 160 mg / l). Foam from a solution containing gelatin in excess (ratio of gelatin: surfactant = 1.39) with the addition of diesel fuel rapidly disintegrates in volume, the height of the column does not exceed 4 cm.

A more stable foam is formed from an aqueous solution of 210-3 mol / L DDSNa + 0.01% gelatin + DT (the height of the column is 18-20 cm, cavities with a diameter of 1 cm are possible.) A stable foam is formed from a solution of the composition 210-3 mol / L DDSNa + 0.1% gelatine + DF: a column of foam 40 cm high is formed within 8 minutes, while no intense destruction was observed in the volume.

Carried out Comparative characteristics stability of a foam column with a height of 2 cm (under the action of P = 2 kPa) with an increase in the content of diesel fuel up to 320 mg / l. The percentage of foam destruction (2 cm high, = 13 minutes) obtained from solutions: 510-4 mol / L DDSNa + 0.02% gelatin + DF and 210-3 mol / L DDSNa + 0.1% gelatin + DF was 95% and 60% respectively.

It was found that the removal of dissolved diesel fuel is most effective with a foam of the composition 210-3 mol / l DDSNa + 0.1% gelatin.

ELECTRIC CONDUCTIVITY OF EUTECTIC MELT

LiNO3 -KNO3-Sr (NO3) 2-NaCL-KCl SYSTEMS

- & nbsp– & nbsp–

Hasanaliev A.M.

Professor of the Department of Chemistry, Doctor of Chemical Sciences, Professor, Dagestan State Pedagogical University, Research Institute of General and inorganic chemistry, Russia, Makhachkala The conductivity of the eutectic composition of the LiNO3-KNO3-Sr (NO3) 2-NaCl-KCl system has been studied experimentally. Using the obtained data and density values, the specific () and equivalent () electrical conductivity were calculated.

Keywords: eutectic, conductivity, electrical conductivity, equivalent electrical conductivity.

Our analysis of the thermodynamic, thermophysical and transport properties of individual salts and their systems showed that chloride-nitrate salt eutectics of alkali and alkaline earth metals have the highest heat storage capacity in the temperature range from 100-3000C. The introduction of nitrates into chloride systems allows not only to reduce the operating temperature and increase the heat content, but also to weaken their corrosive effect on the structural materials of heat accumulators. Invariant compositions of salt melts of chloride-nitrate systems have rather low melting points, thereby attracting attention as low-melting electrolytes, but their use for practical purposes is sometimes difficult due to the lack of data on their properties. One of the most important characteristics of chemical current sources (CPS) is electrical conductivity. In this connection, we have experimentally studied the conductivity of the eutectic melt of the LiNO3KNO3-Sr (NO3) 2-NaCl-KCl system with a melting temperature of 364K. Using the obtained data and density values, the specific () and equivalent () electrical conductivity for a given composition were calculated. Molten nitrates have a relatively low electrical conductivity, which at temperatures Tm + 10K ranges from 0.688 for potassium nitrate to 1.01 for lithium nitrate, but with the addition of chlorides, their electrical conductivity increases sharply.

The graphs of the electrical conductivity versus temperature are expressed in the coordinates ln = f (1 / T). These dependences are needed to calculate the activation energy and elucidate the mechanism of conductivity. The dependence of the conductivity logarithm on the reciprocal of the absolute temperature is shown in the figure. In this case, the electrical conductivity increases by 87.61%.

An analysis of the experimental data confirms the fact that with an increase in temperature, the conductivity of molten mixtures increases by 8 times, which is explained by an increase in the mobility of complex ions, taking into account an increase in their kinetic energy.

Another important advantage of these materials is the low corrosive activity of their melts, due to the passivating action of the nitrate ion on many metals and their alloys.

approximation of spectral curves of arbitrary nature by power polynomials. Some features of using this approach in practice are discussed.

Key words: spectral analysis, decomposition of spectra, power polynomials.

In recent years, in the field of quantitative analysis of mixtures, there has been an active development of methods for mathematical processing of the corresponding spectral data. The most widely used are chemometric algorithms for the decomposition of spectra. For situations in which the application of chemometric approaches is difficult or impossible (for example, with single measurements), reference-free methods of analysis have been proposed, taking into account the inevitable scatter of experimental and theoretical data and giving the result in the form of histograms of the distribution of component concentrations.

The transition to the description of spectra in the form of fuzzy sets is performed using the parametric theory corresponding to each specific type of spectrum (in the case of IR spectra, such parameters are force constants and electro-optical parameters). Mathematically, this corresponds to the representation of the spectrum of each component in the form of a rectangular matrix, the set of columns of which corresponds to spectral curves randomly selected from a given range of possible variations. An example of a "blurred" spectral curve is shown in Fig. 1. The desired solution is found by the method of successive approximations and is reduced to finding the minimum of the squared residuals between the experimental and theoretical spectra of the mixture.

Rice. 1. A set of theoretical IR spectra of benzene obtained by varying the force constants and electro-optical parameters With the available variety of types of spectra and parameters of the corresponding physical models, the question naturally arises of finding a simple universal way to parameterize any analytical signals. Separation of the sum of spectral curves into components is most effective when all spectra depend linearly on parameters, and the number of parameters is small. In the simplest case, these requirements are met by the approximation of curves by power polynomials, which does not depend on either the shape or the origin of the spectra, which was considered in. With this approach, a transition is made to the space for displaying spectral curves by the values ​​of polynomial coefficients - it is these coefficients that make up the columns of the aforementioned rectangular matrices and their variations replace the variation of the parameters of physical models.

Computer experiments have confirmed the efficiency of the proposed decomposition algorithm. A large number of examples of the separation of IR spectra of five-component mixtures of organic substances can be found in. The main problem that arises when using the polynomial representation in practice is that the conditionality tasks approximation of spectral curves by polynomials, deteriorates very quickly with increasing degree of polynomials. This, of course, is not due to the fact that the spectra need to be reproduced as accurately as possible using high powers (example in Fig. 2). The coefficients of the polynomial of any, even the smallest, degree reflect the location of all points of the curve, for which they were obtained, and, therefore, can be used. But the peculiarities of the algorithm are such that the number of rows in rectangular matrices describing the spectra of the components (i.e., the number of polynomial coefficients) must be at least 5-10 times greater than the number of components. In this regard, a number of practical measures are proposed to help overcome the problem of ill-conditioning.

Rice. 2. Fragment of the IR spectrum of toluene (dashed curve) and its representation by a 40th degree polynomial (solid curve) null. In this case, the columns of the rectangular matrices of the spectra of the components consist of the coefficients of not one polynomial, but several.

The number of polynomials is determined by the number of rows required to solve each specific problem. For example, if you want the matrices to have 136 rows, the 135th degree polynomial can be replaced with sixteen polynomials with degrees from 0 to 15. At the same time, when representing curves by polynomials of even small degrees, it is advisable to use scaling and centering by the argument.

The scaling procedure turns out to be useful also because the coefficients of the polynomials at the highest degrees can turn out to be extremely small values ​​(~ 10-16 and less). The peculiarities of data storage in computer memory (64 bits for double precision floating point numbers) make it impossible to directly vary them without taking special measures. However, if the minimum coefficient aNk of the N-th degree polynomial has a value of ~ 10 – D (D 15), then the transition to a new variable x x 10S, where S D 15 N, will provide the possibility of varying all ank. For example, for IR spectra, the transition from wavenumber values ​​in reciprocal centimeters to dimensionless values ​​of 1000 cm1 makes it possible to increase the degree of the polynomial, the direct variation of the coefficients of which becomes possible, from 4–5 to 50.

The choice of the finite interval on which this approximation is performed can have a great influence on the conditionality of the problem of approximating spectral curves by polynomials. There is no need to use the entire spectral range at once (for example, for IR spectra of organic substances, the range of wavenumbers is from 20 to 3500 cm -1, which, as a rule, has extended sections with zero optical density). More preferable are the options for dividing into several overlapping or non-overlapping spectral regions with the possible exception of intervals where the analytical signal is absent.

For each such area, the problem of determining the concentrations of the components can be solved independently (in this case, its conditionality is usually much better than for the problem posed over the entire spectral range). When making the final decision on the most probable values ​​of the concentrations of the components, all the results obtained should be taken into account, but some of them can be discarded, for example, for those areas where the spectral curves of all components are very close.

Dividing the entire range into several intervals also has the advantage that in this way it is possible to select the so-called "windows", i.e. portions of the spectrum in which the contributions of a smaller number of components are present than are present in the mixture. The presence of such "windows" turns out to be extremely useful when analyzing the entire set of results.

IONIC FLOTATION OF SAMARIUM CATIONS

FROM NITRATE MEDIA

Key words: rare earth metals (samarium (III)), ion flotation, distribution coefficients, pH of the aqueous equilibrium phase.

To establish the mechanism of the process and predict the optimal conditions for the extraction and separation of metal cations by methods of extraction, flotation, and ion flotation, it is necessary to know the pH of the formation of metal hydroxo complexes and the pH of hydrate formation, which can be calculated on the basis of the Gibbs energies of the formation of hydroxo complexes and metal hydroxides. The pH value of the beginning of the formation of hydroxo complexes Sm (OH) 2+ can be calculated based on the expression for the persistence constant notSm] a: (1), K OH n [Sm (OH)]

The pH value of hydrate formation is calculated by the formula:

pH hydr 14 13 (lg L lg C lg) (2) where L is the product of the hydroxide solubility, C is the concentration of the samarium cation, ± is the average ionic activity coefficient of the salt.

The value of the Gibbs energy of formation of Sm (OH) 2+ –859.95 kJ / mol, available in, does not correspond to the value of –848.10 ± 3.35 kJ / mol, given in. Due to the large error of the values ​​available in the literature, the determination of the pH of complexation and hydrate formation by the conductometric titration method was undertaken, followed by the calculation of thermodynamic values.

Aliquots of 10 ml of Sm (NO) 3 solution with a concentration of 0.001 molkg1, acidified with nitric acid to a pH of about 3, were titrated with 0.002 N. NaOH solution.

Rice. Dependence of the specific conductivity of the Sm (NO) 3 solution and pH on the volume of the NaOH solution during conductometric titration The Gibbs energies of ion formation in the solution were taken according to the database. The instability constant was calculated using the formula (1).

The activity value (OH) - was calculated from the pH value of 5.81, corresponding to the equality of concentrations = in the formula (1). The average ionic activity coefficient of Sm (NO3) 3 at a concentration of 0.001 mol · kg1 is taken equal to 0.78. The Gibbs energy of hydroxo complex formation was calculated by the formula: f G298Sm (OH) 2 f G298Smaq f G298OH aq RT ln K n (3)

Ionic flotation of Sm (III) was carried out from an aqueous solution of nitrate with a concentration of 0.001 mol · kg1 using sodium dodecyl sulfate (NaDS), the concentration of which was set equal to 0.003 mol · kg 1. A 137 V-FL flotation machine was used, with a chamber volume of 1.0 dm3. ... In the equilibrium aqueous phase after flotation, the concentration of Sm (III) was determined by the photometric method with Arsenazo III and DS- (C12H25OSO3-) by potentiometric titration with 0.002 mol dm3 with a solution of cetyltrimethylammonium chloride with an ion-selective electrode manufactured at the Department of Physical Chemistry of St. Petersburg State University.

Thus, in acidic environment the extraction of Sm (III) is practically not observed. In the range of pH values ​​from 3.5 to 6.5, the distribution coefficient (Kraspred.) Is -13 ± 2. In this pH range, samarium dodecyl sulfates float in the form of Sm (C12H25OSO3) 3 and Sm (OH) (C12H25OSO3) 2. At pH above 6.5, Craspred. sharply increases to 82. Consequently, Sm (III) floats mainly in the form of hydroxide, with an admixture of medium and basic dodecyl sulfates.

ELECTROPHYSICAL PROPERTIES

NANOCOMPOSITE SYSTEM POTASSIUM POLYTANATE -

LAYERED DOUBLE HYDROXIDE

- & nbsp– & nbsp–

Key words: potassium polytitanate, layered double hydroxide, conductivity.

Potassium polytitanates are attracting great attention as promising materials for the production of a wide range of composites intended for instrument making, mechanical engineering, power engineering, and electrical engineering. Modification of potassium polytitanate allows changing its properties.

The structure of potassium polytitanate is formed by titanium-oxygen octahedra of a layered structure and having a negative charge. The structure of layered double hydroxides is formed by analogous octahedra, with the hydroxyl layers having the opposite charge. Due to the similarity of structures, it is of interest to modify potassium polytitanate with layered double hydroxides.

The starting powder of potassium polytitanate was synthesized in accordance with the procedure. We used potassium polytitanate paste (with a PTC content of 38.5%).

Layered double hydroxide based on manganese and chromium cations (Mn / Cr-LDH) was synthesized by the coprecipitation method while maintaining a constant alkaline environment(pH = 10 ± 0.2) from a one-molar solution of a mixture of MnSO45H2O and Cr2 (SO4) 36H2O (MnSO45H2O: Cr2 (SO4) 36H2O = 0.66: 0.33). The pH was kept constant by dropping a KOH solution (3 mol / L).

The resulting suspension of Mn / Cr-LDH was added in portions to a glass with potassium polytitanate paste placed in it. The resulting precipitate was separated by decantation and again filled with distilled water. This procedure was repeated 2 times.

The precipitate separated from the water was placed in an oven and dried at a temperature of 60 ° C for several days. After complete drying, the resulting materials were ground in an agate mortar to a finely dispersed state.

Thermogravimetric studies were carried out on a NETZSCH SDT 449 F3 device for synchronous thermal analysis.For the obtained powder, as well as powders annealed at temperatures of 250 0 C, 500 0C, 700 0C, 900 0C for 2 hours, studies on powder X-ray diffraction were carried out. The studies were carried out on an ARL X'TRA diffractometer.

An impedance meter Novocontrol POT / GAL 30V 2A Electrochemical Test Station was used to measure electrical conductivity. Investigated were tablets compressed from the powder with a diameter of 12 mm and a thickness of 0.35-0.45 mm.

The pressing pressure was 500 MPa. Contacts in the form of a silver-containing paste-contact K13 were applied to the pressed samples.

The thermogram (Fig. 1) shows one endothermic effect with a maximum at 135 ° C with a weight loss (12.07 wt%). It is obvious that the weight loss at temperatures of 80-4000C is associated with the removal of adsorbed water. When heated from 500 to 1000 0C, structural water is apparently removed. The weight loss in this range is 1.34%.

Rice. 1. Thermogram of the nanocomposite potassium polytitanate - layered double hydroxide The obtained nanocomposite, as well as annealed at 250 ° C, were quasi-amorphous, which is confirmed by diffraction patterns (Fig. 2).

The diffractograms of samples annealed at 500 ° C and 700 ° C are characterized by narrow peaks of high intensity corresponding to titanium dioxide (TiO2 anatase). In addition, there are low-intensity reflections characteristic of cryptomelane (KMn8O16) and potassium chromate (K2CrO4). Annealing at 900 ° C results in narrow high-intensity peaks inherent in the KMnTi3O8 compound, as well as low-intensity peaks of Mn1.5Cr1.5O4.

An increase in conductivity in the high-frequency region is observed during specimen firing at 250 0C (Fig. 3). The conductivity of the samples annealed at 500 ° C and 700 ° C is orders of magnitude higher than for the initial samples, and it is linear in the low and medium frequency range. The conductivity of the samples annealed at 900 0C does not depend on the frequency in the low frequency range. In the high-frequency region, the maximum values ​​of the conductivity are observed. Thus, the phases formed during firing make a significant contribution to the electrical conductivity of composites.

splitters, filters and others. Femtosecond laser recording makes it possible to form elements of arbitrary geometry in the volume of transparent samples. Nonlinear processes occur at the focal point of the laser beam, which lead to a change in the optical characteristics of the material, due to which the formation of micro-optical elements is possible. This work is devoted to the study of the influence of laser radiation power on the changes formed in the volume of niobophosphate glass.

Key words: laser recording, glass, femtosecond laser, optical properties.

Femtosecond laser recording can be used to create various integrated optics elements. When focusing with a femtosecond laser, a laser radiation power density appears inside the focal volume, sufficient for the passage of nonlinear processes, as a result of which a local change in the structure occurs in the volume and chemical composition substances. This method can be used to form micro-optical elements in a variety of transparent materials such as glass, plastic or crystals. The characteristics of the elements are critically dependent on the properties of the sample material and the parameters of the laser. This method can be used to fabricate three-dimensional microcircuits in a material.

The main difference when using short-pulse and CW lasers is the absorption mechanism. When using continuous laser radiation, light absorption occurs in the entire volume of the sample if the photon energy exceeds the band gap of the sample, otherwise absorption does not occur. When using a pulsed laser, absorption of light with a quantum energy less than the band gap of the sample is possible. But absorption occurs only in the focus area. Due to the femtosecond pulse duration (10 -15 s), it is possible to achieve energy power densities sufficient for the occurrence of nonlinear processes. In the focal region, due to either multiphoton absorption or tunneling ionization followed by avalanche ionization, a concentration of free electrons sufficient for direct absorption of laser radiation is achieved. The electron plasma absorbs the radiation energy, heats up, after which relaxation occurs with a local change in the structure, composition, and, as a consequence, optical properties.

To study the effect of power on the laser recording process, we used a MiraOptima 900D femtosecond laser (pulse duration - 100 fs, wavelength - 810 nm, pulse repetition rate - 250 kHz).

The radiation power was 7-14 mW, while the pulse energy was 30-60 nJ. Laser radiation was directed through a system of mirrors to the sample. A camera was used to monitor the recording process. Laser recording was carried out in niobium phosphate glasses containing lithium oxide as a modifier. The glass of this composition was chosen for the reason that in such glasses it is possible to create a significant gradient of the refractive index (up to 10-2), thus

Rice. Influence of the laser radiation power on the contrast of the obtained structures As can be seen from Fig. 1, the power has an important effect on the results of laser recording. The highest contrast is observed for the structure recorded at the maximum power. With a decrease in power, the contrast of the resulting structures decreases.

Studies of the influence of recording parameters were carried out at the resource center of St. Petersburg State University "Optical and Laser Methods of Investigation of Matter".

DEFORMATION OF SODIUM CHLORIDE AND CALCITE

IN THE PRESENCE OF WATER, HYDROCARBONS AND THEIR MIXTURES

- & nbsp– & nbsp–

The compaction of sodium chloride and calcium carbonate powders in the presence of their saturated aqueous solutions, hydrocarbons and their mixtures has been studied. It is shown that under the action of non-hydrostatic stresses, deformation occurs only in the presence of a dissolving medium by the mechanism of recrystallization creep, i.e. the most prone to compaction is the pore space filled with aqueous solutions. The compaction rate increases sharply when passing from static to cyclic loading.

Key words: powder compaction, recrystallization creep, non-hydrostatic stress, local supersaturation, cyclic loads.

Introduction. The significantly increased interest in the study of deformation mechanisms and the evolution of porosity of carbonate and salt formations is primarily due to their industrial importance as oil and gas reservoirs. In addition, the storage capacity and permeability of formations as reservoirs or overburden are key technological characteristics when used for storage of gas condensates, as well as for disposal of highly toxic waste or anthropogenic carbon dioxide. The main mechanism of deformation changes under conditions of the upper crust (i.e., at relatively low stresses - from 1 to 10 MPa), when cataclasis and plastic deformation cannot play a large role, is recrystallization creep (pressure solution), which develops upon contact of non-hydrostatically stressed rock with liquids localized in pores or in the form of intergranular layers. The driving force of the process is an increase in the chemical potential of the rock, leading to an increase in the solubility of stressed areas, local supersaturation, diffusion of dissolved material along the concentration gradient and redeposition of material in unstressed areas (pores, cracks). Under natural conditions, recrystallization creep is observed only in the presence of aqueous solutions, while under the action of small stresses, deformation of formations saturated with hydrocarbons does not occur.

The purpose of this work is to find out how the rate of recrystallization creep depends on the ratio of the water and hydrocarbon phases in the pore fluid.

Experimental technique and objects. As an object of research, we used powders of calcium carbonate grade ChDA with a grain size d = 40 ± 20 μm and sodium chloride grade KhCh (d = 350 ± 50 μm). Liquid-wetted powders containing about 20 wt. % of the liquid, which corresponds to the maximum filling of the pore space, was tested for compression in a cylindrical matrix with a piston diameter of 10 mm at room temperature on an IZV-1 device. A constant load on the piston of 90 N provided a pressure of about 1 MPa. The initial height of the samples h0 was 1.0 ... 1.5 cm. Dried decane, liquid paraffin, water (always pre-saturated with the test salt) or a mixture of decane and water were used as liquid media. The automatic displacement sensor LIR-15 recorded the displacement of the piston h with an accuracy of 0.1 μm. 3-4 samples were tested under each condition.

In addition to tests in a static mode, tests were carried out in a variable load mode. A specially designed device made it possible to change the stress on the piston in the range from 0.3 to 0.03 MPa with a frequency of 5 to 120 s according to a law close to sinusoidal.

When loading NaCl and CaCO3 samples impregnated with dried decane, during the first 30 minutes, the initially loose powder rapidly compresses by several percent, after which no further deformation is observed. Partial replacement of the decane with water by thoroughly mixing portions of the powder, previously impregnated with each of the liquids, leads to the fact that noticeable deformation occurs during the entire test period (Fig. 1).

- & nbsp– & nbsp–

An increase in the deformability of the powders with an increase in the content of the dissolving component is evidence that the deformation mechanism is recrystallization creep.

The different form of the dependences of the creep rate of sodium chloride and calcite powders on the mixture composition can be explained by the different wettability of these salts with water: under selective wetting conditions, the aqueous phase forms a contact angle of 5 on a NaCl single crystal, and 80 on a calcite single crystal. Poor wetting makes it difficult to form a coherent network of inclusions dissolving liquid: according to our estimates, at contact angles of ~ 90, the formation of a continuous cluster of liquid inclusions is possible at a relative volumetric water content of at least 60%.

The results obtained are consistent with the work where the compaction rates of pure calcite powders wetted with water and oil-contaminated natural limestone crushed to the same size were compared.

It was shown that while the deformation of pure calcite in three days was ~ 1%, the deformation of limestone practically stopped after 10 hours and did not exceed 0.1%. The gradual displacement of hydrocarbon contaminants by water led to an increase in deformation up to 0.4%.

Thus, in the process of the evolution of host rocks - oil reservoirs, occurring under lithostatic pressure - the pore space filled with aqueous solutions is most susceptible to compaction.

The compaction rate of powders sharply increases upon going from static to cyclic loading, if the medium has a dissolving effect. In fig. 3 shows the curves of compaction of sodium chloride and calcite powder in the presence of saturated aqueous solutions under static and cyclic loads.

Rice. 3. Curves of deformation of powder NaCl and CaCO3 in the presence of saturated aqueous solutions under the action of static and cyclic loads. The areas of cyclic load application are marked with rectangles (legend to the rectangles - the duration of one load cycle). A systematic study of this effect has shown that the cause of acceleration is convective flows arising in liquid intergranular layers during their expansion at the stage of unloading. As a result, at the beginning of the next loading period, the grain is in contact with a solution that is undersaturated with respect to the stressed material; the acceleration of dissolution caused by this entails an acceleration of deformation.

In a number of works, possible mechanisms of the influence of variable low-frequency loads on productive oil wells, leading to the restoration of their flow rate, are considered. It is suggested that a change in the reservoir properties of the medium can occur due to a violation of the equilibrium balance between heavy and light fractions, thixotropic changes in the formation fluid, changes in its viscosity during heat heating, etc. However, the authors admit that “the existing assessments of the role of a particular mechanism in the intensification effect are rather qualitative than quantitative due to the absence of an intensification model as a whole”. The results obtained in this work make it possible to consider recrystallization creep as another mechanism of gradual changes in the porosity of water-saturated sections of the formation, which can lead to a decrease in the content of the water component of oil-water emulsions.

Problems of Applied Mathematics, Mechanics and Informatics

The collection contains two sections: "Analytical and Numerical Methods of Continuum Mechanics" and "Mathematical Methods of Information Security". In the first section, numerical and analytical methods are used to study solutions of nonlinear systems differential equations with partial derivatives. The following tasks are considered: to create, maintain and destroy a tornado, as well as to assess the influence of electromagnetic forces on the development of a tornado; modeling of tsunami behavior in the vicinity of the shoreline using one-dimensional and multidimensional solutions of shallow water equations; a three-dimensional outflow into vacuum of a polytropic gas under conditions of action of mass forces general view; about shockless strong compression. The second section is devoted to mathematical problems of information security. It covers issues of cryptology, coding, secret sharing, parallel programming, analysis of polynomials over finite fields (including irreducible ones), elliptic curves and quasigroups. Complex algebraic problems have been solved, which make it possible to practically implement the general theoretical concepts of information security.
