摘　　要：从精细油藏描述入手,开展了河31断块特高含水期剩余油分布规律及挖潜对策研究。在新认识指导下,确立了断块重建井网、细分层系开发的原则。开发中,应用定向斜井及侧钻井技术、水动力学方法进行调整挖潜。实施后,断块开发效果得到了明显的改善,采收率由42.2%提高到45.9%。此次调整的成功,对类似油藏高含水后期高效挖潜具有重要指导意义。The remaining oil distribution and exploiture countermeasure of the he 31 fault block in the stage with ultra-high water containing is studied by the fine description of reservoir. In the guide of new cognition, we establish the exploiture principle, which is well pattern＇s rebuilding and subdivisioning strata series. So all kind of measures are used including direction-inclined well technology, sidetracking well technology and water dynamics method. As a result, the oil recovery efficiency is improved from 42.2 % to 45,9%. The success of the adjustment gives major guide to develop other reservoirs in high water containing period.
