摘　　要：河流相储层在我国储层中占有相当的比重,但由于其内部复杂的建筑结构,严重的非均质性对油田开发的影响越来越大,剩余油呈高度分散状态.利用测井曲线对储层内分布的薄夹层进行了识别,分析了不同类型河道储层内部夹层个数对剩余油分布的影响及其成因.结果表明:对于水平产状的夹层,夹层个数的增多有利于水驱更均匀,而对于倾斜产状的侧积泥质夹层,由于剩余油主要产于上部封闭、下部开放的角隅处,夹层个数对水驱效果的影响不大.Fluvial facies reservoir occupies large proportion of reservoir in our country, but because of its complicated architecture and serious non-homogeneous effect, the effect of the numbers of sandwiches in channel sand body on the distribution of remaining oil has been analyzed, and the cause of its formation discussed. As to level sandwiches, the growing number of sandwiches is in favor of uniformity of water flood. But to sloping sandwiches, because the remaining oil is in the Wedge-shaped corner, the number of sandwiches has less effect on the effect of water flood.
