摘　　要：针对下二门油田某油组Ⅱ断块的具体情况,建立了三维地质模型和油藏数值模拟模型并进行模拟。充分考虑物性、构造和井网等主要影响因素,对聚驱后剩余油分布规律进行了定性和定量的研究。结果表明,虽然聚驱能在一定程度上减小物性对剩余油分布的控制,但是物性对聚驱后剩余油分布特征仍然存在明显的影响。聚驱后剩余油分布更加集中且剩余油富集区含油饱和度较高,呈条带状和片状分布。断层附近和砂岩尖灭部位是剩余油的主要富集区。In allusion to the condition of Fault Block II in an oil formation of Xia'ermen Oilfield,a 3D geological model and reservoir numerical simulation model were established for simulation.In consideration of the major effects of physical property,reservoir structure and well pattern,the remaining oil distribution law after polymer flooding was qualitatively and quantitatively studied.The result shows that polymer flooding can be used to reduce the control of physical property to the remaining oil distribution,but it still had an evident effect on the remaining oil distribution after polymer flooding.The remaining oil distribution is more concentrated.The oil saturation of the area of remaining oil enriched is higher and it is distributed in strip shape.The sandstone pinchout and the nearby are the areas of remaining oil enrichment.
