储层的微相砂体类型、几何规模特征及分布规律是分析地下油水运动规律和调整注采关系的基础。利用密闭取心、密井网等资料,精细剖析了双河油田ⅧⅨ油组沉积微相及其分布(主要发育水下分流河道、河口坝、前缘席状砂体、前缘浊积体、水下溢岸砂体等5种微相砂体)。同时分析了各小层的砂体组合、前缘相位置、三维连通性、骨架砂体与非骨架砂体之间的相互关系,以小层为单位划分出4类相结构模式:透镜拼合型、透镜连接型、席状互层型、薄层孤立型。
The microfacies type, geometry scale and distribution rule of reservoir are the basis for analyzing the law of underground oil-water movement and adjusting the relationship between injection and production. The sedimentary microfacies and its distribution of Ⅷ Ⅸ oil group in Shuanghe Oilfield (mainly developed submarine distributary channel, estuarine dam, foreland sand body, foreland turbid body, Underwater sediment sand bodies and other five kinds of microfacies sand). At the same time, the relationship between the sand body assemblage, the front phase position, the three-dimensional connectivity, the correlation between the skeleton sand body and the non-framework sand body is analyzed. Four types of phase structure modes are divided into small layers: , Lens connection type, mat-like inter-layer type, thin-layer isolated type.
