System for Rational Control and Management of Oil Production Processes at a Late Stage of Operation

This article discusses the problems of developing rational technologies and remote control systems for the processes of water injection into the reservoir (pumping stations to maintain reservoir pressure) and oil production using mechanized methods (rod pumping units, electric centrifugal pumps, etc.) in the late stage of oil field operation, which is characterized by difficult oil recovery.The main problems of the process of pumping water into the formation to maintain the pressure necessary to displace the oil-water mixture to production wells, and ways to extract them from production wells, are explored. For this purpose, the concentration of water and oil in the total amount of produced fluid is determined depending on the flow rate of the well, and the function of the dependence of the concentration on the flow rate for selected wells is formulated. The problem of optimizing the well flow rate and methods for solving them are posed.The issue of technical and computer software for the optimization problem is considered. A block diagram of the system for rational control and management of oil production processes in the late stage of operation is presented, which allows the implementation of the created technologies, algorithms and software for pumping water into the reservoir through pumping stations for injection and production from wells using deep-well pumps. oil production by achieving an increase in the oil/water ratio when extracting oil using mechanized methods.
