The problems occurred in the production process of weak alkali ASP flooding industrial demonstration area in Class II oil layer of Block A are systematically analyzed, such as the injection pressure of some injection wells rising too fast, the low energy and low yield of some production wells after ASP flooding, and the water cut rising too fast. Aiming at the problem of time, the research work of comprehensive adjustment was carried out, and the effective ways to improve the test effect were summarized Improve the injection-production relationship of well groups and reduce the plane and interlayer differences; Better development results have been achieved by improving the effectiveness of oil wells.
