The Development Effect of Oilfield Can Be Improved by Using Injection-Production System Adjustment

[摘要] Oilfield development has entered into high water cut stage, the development difficulty is increasing, in order to raise recovery ratio and improve the development effect of the block, the injection and production system has been adjusted. The ratio of oil and water wells is reduced by changing the water injection well network; oil and water wells are complemented accordingly, the injection and production relationship of single sand body in this layer is improved; complementation of well network are carried out, and the injection and production relationship of other layers are improved; complementary utilization of well pattern and treatment of inefficient wells are adopted in fault area and so on, good development result is achieved, and it provides reference for development of water-drive remaining oil in future.
