Nowadays there is a number of research papers and a certain interest in some mesoporous materials and the study of their properties. Mesoporous materials have every chance to become components of industrial heterogeneous catalysts. Catalysts based on mesoporous aluminosilicates are widely used in the petrochemical industry for hydrogenation, reforming, hydroisomerization, hydrocracking, hydrodearomatization, etc. In this article mesoporous aluminosilicates (MAS) were synthesized by copolycondensation of tetraethylortosilicate and secondary aluminum butoxide. Hexadecylamine was used as a template. The physico-chemical characteristics of a synthesized structured mesoporous aluminosilicate and a bifunctional catalyst based on it were studied by nitrogen adsorption/desorption, X-ray diffraction, SEM and TPDA. It was found that the obtained samples have an ordered mesoporous structure and possess the necessary strength and concentration of acid centers for use as acid components of bifunctional catalysts of various petrochemical processes.

Deterioration of the qualitative and quantitative characteristics of the hydrocarbon resource base leads to an increase in the share of hard-to-recover reserves. In an environment where the share of hard-to-recover oil reserves in the oil industry is steadily increasing, the need to create effective methods to increase oil recovery is acute. The method of flooding at the present stage of the development of the oil industry is considered the most progressive, meeting the basic principles of oil field development. However, during flooding, a large proportion of oil reserves remains in the reservoir, and therefore, technologies are currently being sought and developed in all major oil companies that will increase the oil recovery coefficient. Currently, there is a growing interest in the application of the technology of water-gas exposure to oil formations to increase oil production. This is due to the fact that the water-gas effects combine the positive aspects of well-known oil production technologies, such as flooding and the method of pumping hydrocarbon gas into the reservoir. Experimental and theoretical studies have established that one of the most effective methods of oil recovery can be methods based on injection of hydrocarbon gases and water-gas mixtures into the reservoir. Experiments were conducted to study the mechanism of displacement and determine the coefficient of displacement of oil by gases and water in various combinations in relation to some fields. The experiments were carried out under conditions as close as possible to reservoir conditions: recombined or reservoir oil samples, core from productive deposits were used. The pressure and temperatures corresponded to their reservoir values. As the results of experiments, the increase in the oil displacement coefficient depends on the type of gas injected (hydrocarbon equilibrium and nonequilibrium with reservoir oil, acidic, inert, etc.) and modification of the injection technology of agents (sequential, alternate, joint). To study the expected results of testing the technology of water-gas exposure at the Kalamkas field, the experience of using this method at other fields is considered. The paper presents an analysis of the experience of implementing the technology of water-gas exposure at various locations. A review analysis of the results of the technology implementation was carried out to determine the advantages and possibilities of using the technology of watergas exposure in the conditions of the Mangystau field.

The properties of formation fluids and reservoir rocks of the Cretaceous and Jurassic periods deposits of the Arystanovskoye field are given in the article. In the A-418 well drilled within a new poorly explored area, the special well logging methods have been used to assess the prospects of the area and identify possible watering out: multi-frequency electromagnetic propagation logging (MEPL) Dielectric Scanner and high resolution nuclear magnetic logging (NML) CMR-Plus. Properties of formation fluids and reservoir rocks of the Cretaceous and Jurassic deposits of the Arystanovskoye field were determined using these methods. The qualitative characters of reservoirs were used for reservoir quality discrimination such as: decreased values of natural radioactivity, volume density and hydrogen content, clay cake availability, availability of radial penetration profile by electrical resistivity diagrams. The results of the research can be used during the selection of development targets, the selection of methods for hydrocarbons recovery. The relevance of this study is confirmed by the fact that the Arystanovskoye field is currently under development. The research of reservoir rocks in the new A-418 well within the 801–3095m interval will help to perform the reserves update and choose the production method.

In the oil refining industry of the Republic of Kazakhstan, catalysts based on synthetic zeolites are mainly used. However, it was found that catalysts of this type have a number of disadvantages. For example, most of them have pore sizes in the micropore range, which is the reason for diffusion limitations. The solution to this problem can be found by creating catalysts based on mesoporous aluminosilicate. Mesostructured aluminosilicates are widely used as catalysts for petrochemical processes due to their high specific surface area, highly ordered pore structure and narrow pore size distribution and the possibility of regulating the size of their pores during synthesis. Mesoporous aluminosilicates are widely used as catalysts for petrochemical processes due to their high specific surface area, highly ordered pore structure and narrow pore size distribution and the possibility of regulating the size of their pores during synthesis. The article presents the synthesis of mesoporous aluminosilicates by copolycondensation of tetraethylortosilicate with various sources of aluminum: secondary aluminum butoxide (MAS-1) and aluminum triisopropoxide (MAS-2). The presence of a mesoporous and ordered structure in the synthesized aluminosilicates was confirmed by the data of low-temperature nitrogen adsorption/ desorption, X-ray diffraction and FT-IR. Acidic data were investigated by the method of infrared spectroscopy of the Fourier transform with diffuse reflection (DRIFT). It is shown that the nature of the aluminum source affects both the specific surface area and porosity, and the acidic characteristics of the synthesized mesoporous aluminosilicates.

Currently, a large number of fields with high-viscosity oil are being developed. Increasing the degree of oil recovery from the subsoil of developed fields using effective methods of active influence is an important scientific and technical task for employees of oil producing enterprises. One of the most effective and promising methods for stabilizing oil production is physical and chemical technologies based on the injection of polymer compositions. Therefore, the authors of the article pursue the goal - to investigate the effectiveness of the use of polymer compositions for further recommendation for use in fields with high-viscosity oils and formations containing hard-to-recover reserves. The article provides an analysis of the results of the study of polymers, namely GL-50 and R-1 on rock samples of various well depths. In this regard, an experiment was carried out to displace oil with various displacing reagents. During the oil displacement experiment with various displacement reagents, the water saturation of the sample and the displacement efficiency were determined. Particular attention is paid to the rate of advancement of the flow of polymers and the propagation of molecules through pores of different diameters. The main goal of this experiment was to determine a more effective polymer for enhanced oil recovery. Comparison of oil displacement efficiency at the stages of polymer injection is given. In the course of the study, the results of determining the displacement coefficients of GL-50 and R-1 polymers were obtained. From the results obtained, it can be assumed that polymer grades have a significant impact on the degree of efficiency of the oil displacement process.

The article discusses laboratory studies carried out to compare the composition of oils from Mesozoic and pre-Mesozoic formations: a comprehensive analysis of the molecular composition of oils by chromatography-mass spectrometry; separation and identification of the composition of alkanes by gas-liquid chromatography; NMR-spectroscopic determination of the fragment composition of oils; mass spectrometry was used to determine the isotopic composition of carbon, which identifies the genesis of hydrocarbons in relation to the zones of oil and gas formation. As a result of the study, the laboratory data were obtained, which made it possible to reveal the similarity between oils from deposits of different ages within the graben-synclines, namely, close values of geochemical parameters and the relative content of individual classes of biomarkers made it possible to assume the genetic unity of oils from the Lower Cretaceous and Proterozoic of the Akshabulak graben-syncline and genetic unity of oils from the Lower Cretaceous and Paleozoic of the Aksai horst anticline. The value of the pristane/ phytane ratios indicates a common environment for the formation of the initial organic matter within the structures - suboxidizing conditions in the Akshabulak graben syncline and oxidizing conditions in the Aksai horst anticline, and the existence of a higher redox potential in the Bosingen graben-syncline. Gas- liquid chromatography data showed a slight difference in the thermal transformation of the studied oils, which were classified as "mature". The results of NMR spectrometry in combination with other methods indicate the genetic unity of oils from the Lower Cretaceous and Proterozoic of the Akshabulak graben- syncline and the genetic unity of oils from the Lower Cretaceous and Paleozoic of the Aksai horst anticline. A comparative analysis of the carbon isotopic composition of oils from the Jurassic and Cretaceous deposits of the Aryskum depression and oils from various basins of the world showed a similar range of their variations and a possible genetic relationship of these oils with organic matter of the sapropel type.

The results of lithofacies studies and paleogeographic reconstructions of the Late DevonianEarly Visean stage and stratigraphic evolution of the Primorskaya zone of uplifts in the south of Precaspian Basin are presented. The complex geological structure of the region is mainly due to the influence of tectonic, volcanic and denudation processes on sedimentation. The spatial distribution of carbonate accumulations in the Primorskaya zone of the Precaspian Basin is determined by the different duration of sedimentation stages and the block structure of the basement. The results of the deep wells drilled in the recent years have made it possible to refine the internal geological structure, justification of new exploration objects in the Late Devonian strata and reevaluate the oil and gas potential and petroleum resources in the south of the Precaspian depression. After recent exploration works, the geological model for the onshore prospective structure traps has been improved, additionally prospective exploration objects have been predicted in the shelf of the Caspian Sea. The most of potential petroleum resources of the Primorskaya zone is the resources of the new offshore exploration objects in Caspian Sea. Non-structural traps can accumulate gigantic hydrocarbon volumes. This is a new highly prospective hydrocarbon exploration direction in the Precaspian Basin

The article deals with specialized software to support the work of production unit operator at refineries. Operators use an emergency response plan to eliminate accidents. These Emergency Response Plans (ERPs) are developed in accordance with the regulatory and legal documents of the Republic of Kazakhstan. However, the amount of information contained in the ERP is quite large. Therefore, printed on paper ERP are quite cumbersome, which makes it difficult to find the necessary algorithm of actions in an emergency situation. The proposed software is an interactive application and can be installed on a variety of electronic media - tablets, smartphones and desktop computers. This allows operators to quickly select and open the necessary algorithm of actions, and also expands training possibilities for operators, which is important for reducing the risk of erroneous actions in accidents and emergencies in production units of oil refineries. The application has been developed in Java-script language using JSON format. The interactive application was experimentally tested in «PetroKazakhstan Oil Production» LLP. The experiment showed that the time spent by the operator on elimination of accidents when using the developed specialized software was on average 15% less than when working with the plan printed on paper, and 30% less than when working with the plan in memory. These experiments also showed that the software almost completely eliminated operator errors. This confirms the effectiveness of the developed interactive application in practice.

Operators use an emergency response plan to eliminate accidents. These Emergency Response Plans (ERPs) are developed in accordance with the regulatory and legal documents of the Republic of Kazakhstan. However, the amount of information contained in the ERP is quite large. Therefore, printed on paper ERP are quite cumbersome, which makes it difficult to find the necessary algorithm of actions in an emergency situation. The proposed software is an interactive application and can be installed on a variety of electronic media - tablets, smartphones and desktop computers. This allows operators to quickly select and open the necessary algorithm of actions, and also expands training possibilities for operators, which is important for reducing the risk of erroneous actions in accidents and emergencies in production units of oil refineries.

The article presents the experimental results of studies of the filtration properties of oils from fields with a high content of asphaltene-resinous substances. Experimental studies of the filtration process of deposits with a high content of asphaltene-resinous substances have established that in low-permeability, unlike high-permeability reservoirs, the beginning of filtration proceeds according to a nonlinear law, and with an increase in the pressure gradient, the nonlinearity turns into a straight line corresponding to the Darcy law. In addition, the results of experimental studies on the displacement of oil from fields with a high content of asphaltene-resinous substances by polymer solutions on artificially created reservoir models are presented to determine the concentration of the polymer solution and the size of the slug to increase oil recovery from reservoirs. Experimental research on oil displacement by polymeric solutions were carried out on reservoir models filled with quartz sand, while the analyzed deposits are represented by carbonate limestone rocks. The results obtained on the oil displacement by polymer solutions on reservoir models with terrigenous reservoirs are considered possible for use on objects with carbonate reservoirs with a qualitative justification for the introduction of the polymer flooding method. Experimental studies on the oil displacement from fields with a high content of asphalteneresinous substances with a thickened water rim have established that this method gives the greatest increase in anhydrous and ultimate oil recovery, within a change in the concentration of the polymer solution of 0.2-0.4%, with a rim size of more than 70% of the oil-saturated reservoir volume. Studies on the displacement of high-viscosity oils with polymer solutions have shown that the use of this method of increasing the oil recovery factor in practice is not always economically feasible, due to the need to provide high injection pressures and a high concentration of an expensive polymer solution.
