本文重点分析该区块注采系统调整见效初期的地层压力特征,针对油井压力上升较快,以及全区地层压力在平面和纵向上的不均衡状况,分析问题成因,研究合理注采比的确定及调整方法,使北三东压力不均衡状况得到改善,保护注采系统调整效果。
This paper focuses on analyzing the stratigraphic pressure characteristics of injection and production recovery in this block. In view of the rapid rise of oil well pressure and the imbalance of formation pressure in both horizontal and vertical directions in the whole region, the causes of the problem are analyzed, and the reasonable ratio of injection to production is determined And adjustment methods so that the pressure imbalance situation in North Third East has been improved and the effect of adjustment of injection and production systems has been protected.
