桥口复杂断块油藏高效开发模式探讨

桥口油田是典型的复杂断块油藏，油层多，非均质性强。由于强注强采，含水迅速上升，产量大幅度递减，开发效果变差。桥口油田进行了多年的研究和探索，并且形成了一套高效调整井设计、剩余油分布规律的研究以及层系转移等适合复杂断块油藏中高含水期的高效开发模式，这 一套模式是在同类油藏的开发上具有一定推广价值。

The Discussion on High Efficiency Production Mode in Qiaokou Complicated Block Oil Reservoir

Qiaokou Oilfield is a typical complicated block oilfield with multiplicate oil layers which is more heterogeneous,with the strong water injection and oil production,The water cut rise quickly and the oil production decrease greatly.Under the condition that well pattern has finalized the design and no new reserve can be plunged into. It is a serious problem faced to the oilfield production technologist how to use present well pattern to achieve stablizing production.With years study and reseach in this aspect,we find a suit of technology that include high efficiency of adjustment well design;The inspection,study,interpretation of remaining oil distributing regulation;single well plug,dividually water injection and increase water injection as leading remain oil potential tapping technology in complicated bolck oil reservoir.Appling this technology to the Qiaokou Oilfield,we gain good result of stablizing production.The technology has instructive significance and can be used for reference to other congener oil reservoirs.
