秦皇岛油田北区边底水油藏剩余油分析

Analysis on Residual Oil of Edge and Bottom Water Reservoir in Northern Qinhuangdao Oilfield

通过油藏数值模拟和室内岩心物理模拟实验,分析了层内剩余油和层间剩余油运移规律及富集区。研究表明,致密隔层对水运移有一定影响,隔层顶部是剩余油富集区域,受岩心渗透率差异的影响,层间干扰和隔层控制剩余油同时存在。

By means of reservoir numerical simulation and laboratory core physical simulation experiment, the remaining oil and interlayer residual oil migration rule and enrichment area in the layer were analyzed. The results show that the dense partition has a certain influence on the migration of water. The top of the partition is the remaining oil enrichment area, which is affected by the difference of cote permeability, and interlayer interference and the remaining oil were controlled by the partition.
