摘　　要：濮城油田东区沙二段下亚段储层沉积微相主要有河道、河道间、前缘席状砂及远砂坝等类型.探讨了沉积微相对储层微观、层内、层间及平面非均质性控制作用,并在此基础上,以油藏动态资料为依据,分析了油层水淹情况、吸水和产液状况以及剩余油的分布状况.沉积微相控制储层的非均质性和油水运动规律;前缘席状砂、河道间及远砂坝等沉积区剩余油相对富集,是今后调整挖潜的主要对象.For lower Member Ⅱ of Shahejie Formation in the eastern Pucheng oilfield, the sedimentary microfacies are mainly characterized by various types of sandbody such as river channel, interchannel, frontal sheet and distal bar. The microfacies may control microscopic, interlayer, intralayer and areal heterogeneity of the reservoir, and its water flooding and absorption, fluid production and residual oil distribution can be analysed according to its performance data. It is clear that the reservoir heterogeneity and fluid movement are controlled by the microfacies, and the residual oil is relatively concentrated in frontal sheet, interchannel and distal bar sandbodies that could be the major targets of adjusting development and tapping production potential in the future.
