摘要
受边水活跃的影响,强边水油藏开发后期会因层内非均质性的影响而导致水窜现象的发生,开发效果受到影响。为了进一步提高该类油藏采收率,在大港油田应用CDG驱油技术进行现场试验研究,设计方案实施后井组综合含水降低5.76%,阶段采出程度提高3.74%。
Due to the active edge water and inner heterogeneity of layer in strong edge water reservoir, the water breakthrough happens in development tail. The phenomenon affects the development effect of the reservoir. Dagang Oilfield does the Field Test Research through adopting the CDG flooding technology, in order to. enhance oil recov- ery, the implementation of scheme result to composite water cut of the well group decreases by 5.76% , recovery percent of reserves - in phase increases by 3.74%.
