由于胜利油田注水开发进入特高含水开发后期,如何提高水驱开发效果。笔者通过研究认为:1.建立细分韵律层地质模型是保证单元稳定开发的基础;2.对于处于特高含水期的反韵律油藏,对位于侧缘相带或岩性较差的非主力低压韵律层,单独部署一套井网;3.层间层内差异较大的反韵律油藏,在特高含水期,开展堵水调剖是可有效改善开发效果的措施。
As Shengli Oilfield waterflood development into the late development of ultra-high water-cut, how to improve the development of waterflooding effect. The author thinks that: 1. The establishment of sub-layer prosodic layer geological model is to ensure the stable development of unit basis; 2. For the anti-rhythm reservoir in the ultra-high water cut period, on the edge facies or poor lithology non-main force Low-pressure rhythm layer, a single well pattern is deployed. 3. Anti-rhythm reservoirs with large difference in interlayer layers can effectively improve the development effect during the ultra-high water cut period.
