综合运用岩心观察描述、测井相分析资料，剖析了双河油田扇三角洲前缘沉积微相类型，认为其主要发育水下分流河道、河口坝、前缘席状砂体、重力流砂体、水下溢岸砂体等微相砂体。不同微相砂体具有不同的几何规模、物性和平面分布特征，决定了其不同的产液、吸水能力及注水运动方向。因此研究沉积微相与油水运动规律的关系，对找准剩余油富集区，调整和部署注采井网有着重要的实际意义。

Using the data of core observation and electrofacies analysis synthesizely, this paper dissected the type of microfacies of fan delta front in Shuanghe Oilfield, and concluded that five microfacies are developed including distributary channel, mouth bar, front sheet sand, gravity flow sand and overbank sand. Different types of microfacies have different features of geometrical scale, physical characteristics and plane distribution, which determines the production, injection capacities and the direction of movement of in-jected fluids. So to study the relationship between sedimentary microfacies and oil-water movement will be significant for finding
remaining oil and modifying the flooding well patterns.
