摘　　要：高含水期陆相复杂断块层状油藏剩余油分布复杂 ,油藏模拟难度大。马 11复杂断块油藏在油藏精细描述基础上 ,利用动静态综合分析研究与密网格大规模数值模拟研究相结合 ,提高了剩余油研究精度和可信度 ;在此基础上 ,针对油藏剩余油分布特点并结合当前经济技术条件 ,部署实施了以调整井、调剖、堵水、油水井大修为主的剩余油挖潜方案 ,油藏含水上升率大幅度下降、采油速度上升、采收率提高了。The oil remaining distribution is complicated in high water content ratio continental facies complex fault block oil reservoir, so the reservoir simulation is difficult. In this paper, the dynamical static data was obtained based on the reservoir detailed description of Ma 11, the result combined with thick gridding simulation to study the oil reaming distribution. Aimed at the reservoir oil remaining specialty and economic technology, put into effect the plan of the improvement the oil remaining production potential which consisted of the adjustment well, profile modification, water plugging, well major repair etc. Now, the reservoir water cut smart decline, oil recovery rate is climb and the recovery ratio improve 0.7 percent. The fact proved, this means improves the precision and reliability of oil remaining distribution study.
