. Abstract. This article deals with the development of a hardware-software complex for identifying the pit rock displacement that allows measuring continuously several parameters and notifying in a timely manner the personnel of mining enterprises that carry out development by underground and surface methods. The software included in the hardware-software complex is easy to use and allows making changes to the information interface. The hardware-software complex collects, processes and analyzes the data from fiber-optic sensors that control the geotechnical state of the adjacent rock massif. The hardware-software complex is connected to fiber-optic sensors using optical conductors, thus eliminating the use of an expensive copper cable. Fiber optic sensors are intrinsically safe and explosion-proof, they also have a high immunity to electromagnetic interference. The hardware-software complex with fiber-optic sensors makes it possible to implement the monitoring of the pit workings geotechnical state.

. One of the major and big problems of the oil industry is the deposition and crystallization of paraffin. This process can appear at any point in the design of the production process. Wax precipitation is a thermodynamically controlled process that leads to an increase in the viscosity of the oil mixture, a decrease in the internal diameter of wells and pipelines. Wax appearance temperature (WAT) is one of the important characteristics of the wax deposition process. To manage this procedure, it is required to mathematically accurately forecast the temperature at which the wax possibly could appear, to analyze the phase equilibrium of the system. This article discusses the development of a thermodynamic theoretical model for calculating the paraffin precipitation, using a mathematical approach and experimental data. To consider the issue of phase equilibrium, the fugacity parameter of the pure component is analyzed.

. The paper considers the actual task of developing mathematical foundations for algorithmization of the processes of modeling pollution of reservoirs. In the course of long – term studies of the distribution of phytoplankton of the Kokshetau lakes group, in particular, Lakes Zerendi, Kopa, Shalkar, Imantau, measurements of chemical parameters of water, organoleptic properties, transparency were carried out. These data were used to detail individual results and construct forecast values that depend on fluctuations in indicators that characterize the state of hydrobiota. In modeling, a lake is considered as a complex system, and surface sampling points are considered as sources of information about the state of a water body at certain time intervals. The solution of the task is carried out by constructing a critical area, and the incoming information is ranked by the level of significance. The hypothesis is the statement that a certain forecast value is accepted if it enters a certain critical area limited by the values that are determined as a result of experimental measurements. The advantage of the proposed approach is the possibility of simultaneous comparison of the influence of many factors, as well as the use of both empirical and theoretical frequencies.

. The proposed article analyzes the issue related to the preparation of the wellbore for cementing the drilled interval of the well. It has been revealed that poor-quality cleaning of the well bore, including the existing cavities from drilling, brings great problems to the drilling process. For example, in conditions of insufficiently effective removal of cuttings to the surface due to the presence of a gradient layer in the flow of flushing fluid and stagnant zones in the caverns, accumulation of drill cuttings occurs. In the process of well placement, due to changing hydrodynamic conditions (pressure and flow fluctuations) when performing technological operations (flushing, development, drilling, tripping, etc.) and at certain volumes of the accumulated sludge volume in the cavity, it slips into the wellbore wells. As a result of the drilling tool sticking in many wells, sticking of the string with loss of a certain part of the wellbore takes place.

. In this article, the authors have done statistics on the parameters of 3D seismic field work using new methods of attribute analysis to extract structural features. Tectonically, the studied area is confined to the central part of the South Mangyshlak trough. The structures under consideration are Kurganbai and Bayram-Kyzyladyr, located within the Zhazgurli depression and the Great Mangyshlak flexure. Within the framework of the Kurganbai and Bayram - Kyzyladyr structures, previous 2D seismic surveys were mapped. The authors revised the geological structure of the area on the basis of 3D volumetric seismic survey materials, which allowed to obtain new data on the structure of the main structures. The main purpose of the authors works is to describe the structure of Kurganbai and Bayram-Kyzyladyr and to predict local objects promising for the search for oil and gas deposits. The authors present the current understanding of the geological structure of the sites under consideration, which is based on the materials of detailed 3D seismic surveys and drilling data. The raising of Kurganbai complicates the northeastern part of the Bayram - Kurganbai shaft, along the reflecting horizons V3 and V2II has a block structure. The Bayram – Kyzyladyr uplift along the V3 reflecting horizon is a brachianticlinal fold, which is divided by a series of tectonic disturbances into a number of blocks gradually sinking in a southeasterly direction. The uplift mainly consists of three half-arches adjacent to the transverse discontinuous faults.
