摘　　要：为了进一步提高河 31断块的采收率 ,从精细油藏描述入手 ,开展了特高含水期剩余油分布规律及挖潜对策研究。应用定向斜井及侧钻井技术、水动力学方法等进行调整挖潜。经矿场实施后 ,水驱开发效果得到了明显的改善 ,采收率由 42 .2 %提高到 45 .98%。实践证明侧钻井、定向井、水动力学方法是复杂断块挖潜的有效方法。In order to enhancing oil recovery of He 31 fault block further, rules of distribution and measures for tapping potential of the remaining oil in extra high water cut period are studied started with fine reservoir description. Many techniques are applied to adjustment and tapping potential including directed drilling, sidetrack drilling technique and hydrodynamic methods. After field practice, the effect of waterflooding development is improved obviously, and recovery efficiency increased from 42.2% to 45.98%. It is proved that the above measures are effective on tapping the potential in the complex fault block reservoirs by field application.
