摘　　要：针对濮城油田文 5 1块沙二下油藏特点 ,细分了流动单元 ,运用油藏精细描述技术研究了微构造和储层沉积微相 ,建立了油藏构造、砂体及储层物性三维模型。通过各种动态监测资料综合分析和密网络大规模精细数值模拟研究 ,搞清了剩余油分布状况。在此基础上提出并实施了油藏开发调整措施 ,使油井含水下降 ,产量增加 。According to the characteristic of the lower Sha 2 reservoir in Block 51, this paper subdivides the flow units. It uses reservoir fine geologic description technique to study the micro structure and reservoir sedimentary micro phase and construct a 3D model of reservoir structure, sand body and reservoir property. Through a comprehensive analysis on various dynamic monitoring data and a large amount of fine numerical simulation study of dense grid, it makes clear the residual oil distribution. Then it proposes and performs reservoir development adjustment measures to increase oil production and decrease water cut so as to improve oil recovery.
