Abstract

The purpose of the work is to analyze the efficiency of oil displacement by various agents, such as water and gas, in different modes. The methods and technologies used to increase oil recovery are considered, as well as the influence of various parameters on the efficiency of the process.The authors describe in more detail the method of water-gas exposure (VGV) using pumping-ejector systems (PES) to provide a triple effect on oil reservoirs by simultaneous or alternate injection of water and gas. Theoretical and experimental methods were used to conduct the study. The study and analysis of scientific sources on the issue of evaluating the effectiveness of oil displacement became the first stage of the study. Then laboratory tests were carried out to assess the effectiveness of oil displacement by various agents. Based on the results of the work done, it was concluded that the degree of influence of wetting processes on the final result of displacement is an extremely important factor. The uniqueness of this article lies in the study of the possibilities of using multithreaded ejectors to increase the efficiency of extraction of hydrocarbones.
