摘　　要：以东营凹陷梁家楼油田北区沙三中油藏为例 ,应用流动单元方法研究高含水油田剩余油的分布规律。在流动单元划分中选取了孔隙度、渗透率、粒度均值、泥质含量及流动层指数 5个参数 ,应用聚类分析方法 ,将储层划分为A、B、C 3类流动单元 ,优选出截断高斯模拟方法对流动单元进行了井间预测。研究表明 ,剩余油主要富集在正韵律储层中、上部的B、C类流动单元区 ;平面上 ,剩余油主要分布在物性相对差的B、C类流动单元区及以A、B类流动单元为主的断层附近的无井控制区域。用此方法预测的剩余油富集区与数值模拟结果吻合较好 ,应用效果分析表明 ,用流动单元方法研究剩余油分布是可行且有效的。The flow unit method was applied to study remaining oil distribution in the high water-containing oilfield by using the data of the Shahejie Formation in the Liangjialou Reservoir.The parameters such as porosity,permeability,mean value of the grain sizes,shaleness and flow index were selected to classify the flow units.By the use of the cluster analysis method,reservoir flow units were classified into three types of A,B and C.Then,the truncated Gaussian simulation method was optimized to predict the inter-well distribution of flow units.The result shows that the remaining oil was mainly distributed in flow units B and C of positive rhythm reservoir as well as flow units A and B without oil wells near the fault.The remaining oil distribution predicted using this method coincides well with the result of numerical simulation.Practical application shows that this method is feasible for predicting the distribution of remaining oil.
