摘　　要：双河油田Ⅳ1-3层系处于高含水、高采出程度和剩余油高度分散的“三高”开发期,但仍有相当数量的剩余油。储层沉积微相的特征与组合是决定砂体非均质性的主要因素,也是产生大量剩余油的根本原因。通过密井网资料对该层系进行精细解剖,建立储层沉积微相模式,与现井网结合确定剩余油分布类型和地区,指导高效井的部暑。经现场实施,取得了良好效果。Shuanghe oilfield FV1 - 3 layer still at the stage of high water cut, high collection degree and high distribu- tion of residual oil, there still remained certain amount of residual oil Characteristics and combination of reservoir sedimentary facies is the main factors to determine sand body heterogeneity and that is the main reason to produce a large amount of residual oil. According to close well pattern data, we have made fine explanation of this sequence and fest up reservoir sedimentary facies model, which determined distribution type and area of residual oil combining with existing well pattern and directed high effective well disposition. We have achieved good effect upon the execution of the work at site.
