“…To calculate the distribution of pressure at given points, the contour lines of the formation in the water-driven or elastic regime use known solutions to problems [8,9]. Fluid inflow from an unrestricted circular reservoir to a runoff point or to the circular contour of an enlarged well is calculated using the well-known formulas of Carslow and Van Everdingen [9,14].…”

Identification of the regularity of pressure in the oil reservoir, considering the regularity of improving the method of control and reservoir development. The study used theoretical and experimental analyzes of the results with the use of software. The results of the study will improve the accuracy of the design and development of oil and gas fields and can be used to improve the production technology of oil fields at their later stages of development. Taking into account the angle, the pressure distributions in the reservoir are changed in a circle, a new model is proposed in which the pressure dynamics is changed, it is solved by a two-dimensional problem taking known solutions. According to the known distribution of pressure in the reservoir, obtained experimentally, the characteristics of this parameter along the axis of the segment of the oil reservoir are fixed under changing boundary conditions. A mathematical model is proposed that considers the distribution of pressure along the angle of inclination of wells, will improve the prediction of pressure distribution in producing wells, which leads to the improvement of methods for monitoring and regulating development in oil fields.

Purpose. Establishment of regularities of variability of pressure dynamics in the reservoir and development on this basis of methods of control and regulation of hydrocarbon production. Methodology. To achieve this goal, experimental studies were conducted, and the results of the experiments were summarized. Findings. Pressure distribution functions for stationary fluid inflow in two planes have been established, which allow monitoring and management of mining operations, especially at late stages of development. Originality. Based on the established regularities, a model of pressure distribution in the reservoir in a two-dimensional plane has been created. An experimental study of the pressure distribution in the reservoir was carried out, which allowed us to remove the characteristics of the pressure distribution along the axis of the segment of the oil reservoir under varying boundary conditions. Practical value. A mathematical model of pressure distribution processes along the angle of inclination is proposed, which allows determining the effectiveness of flooding. The influence of the deformability of the formation, the location of the well relative to its impenetrable roof and sole, the length of the horizontal trunk and the power of the opened formation on the magnitude and intensity of the inflow to the horizontal well is estimated.

DevelopMent of An effectIve MethoD for ZonInG the eArth's surfAce In heteroGeneIty of the rocK MAss purpose. Development of a method for zoning the field surface according to the degree of problem by the criterion based on changes in the geoenergy of the rock mass, determined by the difference between the sum of potential gravitational energies and elastic deformations of the rock mass in the initial and current states. Methodology. The research was performed using methods of causeeffect analysis, physical modeling and geomechanics. findings. The method for zoning the field surface according to the degree of problem is developed on the basis of energy pa rameters determining the state of a heterogeneous rock mass and characterizing the general laws of manifestation and development of geomechanical processes. The method allows us to identify potentially dangerous areas on the earth's surface that are at the stage of involvement in the process of displacement, and therefore cannot be identified by ground observations and remote sensing methods. Based on the method, recommendations for optimizing geodetic monitoring have been developed. originality. A method has been developed that increases the reliability of the zoning of the earth's surface of the field according to the degree of problematicity, based on a criterion involving parameters that determine the geoenergy of the rock mass in the current and initial states. practical value. The method improves the quality of situational control, predicts the occurrence of risk situations and their development, and optimizes geodetic monitoring.
