跃进二号东高点油田是一个长井段、高丰度的复杂断块油藏,断层复杂,储层非均质性强,经过16年的注水开发,油藏已经进入中高含水期,注采矛盾日益加大,水淹复杂,水驱储量动用程度逐年降低,剩余资源分布复杂;复杂断块油藏中高含水期稳油控水关键技术研究是该油藏现阶段开发的必要研究课题,本文探讨了如何提高水驱储量动用程度、降低含水上升速度、缓解油藏自然递减的几项关键技术。
Yuejin No. 2 Donggao Point Oilfield is a long well section and high abundance complex fault block reservoir with complicated faults and strong reservoir heterogeneity. After 16 years of waterflood development, the reservoir has entered the middle and high water cut period. Note The complexity of flooding and the degree of utilization of waterflooding reserves are decreasing year by year with complicated distribution of the remaining resources. The research on the key technologies of water diversion for stable oil control in complex faulted block reservoirs is a necessary research topic for the current development of this reservoir. This article explores several key techniques of how to increase the utilization of waterflooding reserves, reduce the rate of water cut-off, and ease the natural decline of oil reservoirs.
