The ternary compound flooding of the second-class oil layer has achieved good effects of increasing oil and dewatering in the field test. However, during the promotion process, the injection and production conditions are unstable. Seems particularly important. This paper selects the typical well group in the weak alkaline ternary compound flooding block of the second-class oil layer in a certain area, conducts potential analysis on the problems existing in development, strictly controls the injection quality at the injection end, and adopts measures such as sub-injection, parameter adjustment and fracturing Injection capacity, improve the utilization of the oil layer; the corresponding fracturing at the production end, improve the connection relationship, improve the utilization of the thin layer, maximize the potential of remaining oil, synchronize the tracking and adjustment methods at the injection and production ends to extend the fracturing During the stable period, the development effect of the well group is improved, which provides a technical basis for solving similar problems in the future, and can further improve the oil displacement efficiency of the ternary compound flooding.
