Water cut analysis and optimization of injection–production​ system for densifying well network
Energy Reports, 2022 Based on the historical information and production status of the oil field, the production situation and the main contradictions that exist at present are analyzed. In response to the problems of the low number of water wells and imperfect injection and recovery well types after block encryption adjustment, this paper proposes two adjustment schemes ...

Open Journal of Yangtze Oil and Gas, 2020 This paper proposed a method of injection-production system adjustment to solve the problem that the water flooding effect was restricted because of the horizontal and vertical contradictions during the development process of fault block reservoirs. Considering the heterogeneity of reservoir, the Buckley-Leverett water flooding theory was applied to ...
