Currently, the oil and gas segment of Kazakhstan is facing such a problem as paraffin deposits. The problem associated with the deposition and crystallization of paraffin causes large-scale difficulties, and models for predicting wax precipitation are limited to specific types of oil, and therefore there is a need to improve them. The authors of this article analyzed and developed a predictive model of paraffin deposition from crude oil for Kazakhstani fields. The work is based on the study of Lira-Galeana et al., which considers the multicomponent deposition of immiscible solids from an oil mixture - a multi-solid model. During the study, it was found out that the Lira-Galeana model uses the equation of state, the volatility properties of the components and the activity coefficient. The Poynting effect was considered at high pressures in the system. For experimental studies, oil samples were taken from two fields. The component composition of the oil, the pour point and loss of fluidity of the oil, as well as the melting point temperatures were determined in laboratory conditions. The amount of paraffin sludge from the oil was estimated experimentally. The results obtained are fully consistent with the analytical solution. During laboratory tests, it was found that the oil from the second field was heavier, and the degree of crystallization of paraffin was more significant than that of oil from the first field under the same conditions. Using this predictive model, the authors were able to predict the amount of solid precipitation from crude oil during the year, depending on changes in ambient temperature.

For difficult operating conditions of oil wells, one of the most effective methods of mechanized extraction is the use of progressive cavity pump with surface drive, providing a complete or partial solution to the problems of high-viscosity oil production. The volume of oil production and the cost of oil directly depend on their trouble-free operation, therefore, measures to improve the efficiency of progressive cavity pump, optimize pump operation, identify and combat the causes of premature failure of underground equipment are an urgent issue. This article analyzes the reasons for the workover of oil wells operated with progressive cavity pumps at the «Ashchysai» oilfield. In order to ensure long-term operation of the pump, the main parameters controlled during the operation of the rod column are determined, and the method of their calculation is demonstrated. Recommendations have been developed for choosing the optimal operating mode of the pump. The analysis of the efficiency of using polymer-coated tubing in wells equipped with progressive cavity pumps, increasing the intercleaning period and inter-repair period of wells.

Electric submersible pumping units are used for production in high-yield oil wells. Since existing pumping units come in different types depending on the complexity of the design and well conditions, a clear and responsible decision must be made in terms of reliability. In the article, in connection with the widespread use of electric submersible pumping units at oil fields, the methods of solving the issue of ensuring the performance of the equipment, namely, achieving reliability and control of technical condition in the conditions of its operation are considered. In relation to regional oilfields the well efficiency indicators were determined and a comparative analysis is presented. The analysis allows to study the problems of failures of wells equipped with submersible pumps with low service life. The aim of the study is to improve the reliability of the electric centrifugal pump during operation.

In this item, the top-priority is organization of reservoir pressure maintenance system and fields development under natural mode in order to maintain reservoir pressure in carbonate fields. Currently, the fields are being developed in a natural drive, and arranging a system for maintaining reservoir pressure is a top-priority. Carbonate fields are complicated by tectonic faults in the separate blocks and HC production reveals disturbance of the balance in the geological environment. Longtime fluid sampling without reservoir pressure maintenance leads to change of stress fields in formation, which initiates creation of deformations of earth surface. In order to prevent from these events, it is required to maintain reservoir pressure. It is necessary to maintain reservoir pressure to prevent these events from happening. When water is injected, migration occurs through a complex ramified system of cracks, caverns and pore channels. The most permeable in the productive thickness layer are karst intervals and zones of increased fracturing, which serve as the main routes for fluid migration. Considering complication of RPM system organization due to high wellhead pressure, field distance from water sources and possible creation of cavity and carst, conception of carbonate fields development is developed within the frame of item.

Enhanced oil recovery from active fields is equivalent to the discovery of new fields, making this issue critical to all oil-producing countries around the world. Of course, among all modern methods of increasing oil recovery from reservoirs, thermal methods are the most technically and technologically prepared. They make it possible to extract oil with a viscosity of up to 100 MPa and at the same time increase the final oil recovery by 30-50%. In particular, the thermal steam method is widely used both in fields in the CIS countries and abroad. The main factors that determine the growth of oil production using thermal methods include: Availability of significant resources of high-viscosity oil. Application of highly effective technologies for influencing oil deposits. Availability of necessary heat and power equipment. Use of heat-resistant equipment for wells and on the surface. Effective control and regulation of processes inside wells. The widespread development of methods for thermal oil production is associated with the solution of a complex set of scientific and technical problems. Among these tasks, special attention is paid to: The study of oil recovery mechanisms in various geological and physical conditions. The determination of opportunities for effective use of the features of the geological structure of specific fields. The development of combined methods for increasing oil recovery, including thermal methods and others, in order to improve technological processes and achieve high oil recovery rates at the level of 50-60%. The aim of this article is to analyze and justify the choice of a specific thermal oil production technology, namely the method of steam-cyclic well treatment, which is especially relevant for the production of high-viscosity oils.

The operation of sections of main gas pipelines that are on the verge of developing a design resource is associated with a number of problems in ensuring industrial safety. One of the most acute problems is the occurrence of local defects. The main material for the manufacture of main gas pipelines is steel. During the operation of the pipeline, local defects occur due to metal corrosion or mechanical damage to the gas pipe. Such concentrators with high internal pressure in the gas pipeline can lead to the destruction of the entire structure. In this case, the situation of destruction is especially critical, since it can cause a man-made disaster. To increase the shelf life of damaged sections of main pipelines in places where defects are located, banding with composite linings is used. The article contains part of a comprehensive study, which consisted in the development of methods for modeling the main gas pipeline for oil and petroleum products under seismic loads, dynamic stress-strain state under the influence of seismic loads and stress-strain state of a damaged gas pipeline reinforced with composite linings under the action of internal pressure. The technology of manufacturing linings from composite material is also described in detail. At the same time, a geometric model of the section of the main gas pipeline with composite linings was developed and an analysis of the loading of the section of the main gas pipeline in ANSYS was carried out, provided that the lining is mounted without tension on the pipeline and provided that the lining is mounted with tension, where a comparative analysis showed that the installation condition of composite linings does not significantly affect the static stress state.
