The relevance of the study is caused by the need to summarize the accumulated experience and information on application of generally accepted methods for analyzing the effectiveness of the pressure maintenance system, identifying the advantages and disadvantages of each individual method, and formulating recommendations to simplify the efficiency analysis, while increasing the depth and quality of the analysis, which in the future will reduce production losses oil. The research aim is to formulate recommendations for improving the process of analyzing the effectiveness of the oil flooding system. The research subject: Southern licensed territory of the Priobskoe field (Khanty-Mansi Autonomous Okrug). The research methods: Correlation analysis of existing methods of evaluation of water-flooding oil reservoirs, identification of strengths and weaknesses, development of an integrated approach to the use of methods of analysis of effectiveness of waterflood, and assessment of prospects of application of research results. The research results. The paper discusses a methodology for optimizing the process of analyzing the effectiveness of a waterflooding system for oil fields by dividing them into smaller hydrodynamically closed sections of the reservoir-blocks (waterflood cells). To prevent loss of quality of the analysis, a transition from a reactive approach to diagnosing losses to a proactive one is proposed, which allows predicting and preventing a decrease in oil production. Based on the tendency to enlarge the sections of the reservoir to be analyzed, in comparison with traditional methods of analysis, and implement a proactive approach, an algorithm is proposed to increase the efficiency of base production management-proactive block factor analysis. The prospects of applying the results of block-factor analysis on the example of one of the blocks of the Priobskoe field (Khanty-Mansi Autonomous Area) is considered. It is possible to adapt the presented analysis algorithm to the necessary geological and physical conditions of other layers in order to adapt this technology in other oil and gas provinces.
