摘　　要：以层次分析思想为指导,应用结构要素分析法,结合露头研究,解剖层内薄夹层并对砂体内部建筑结构进行详细研究,认为这样就可以预测性地描绘出胜利油区河流相单砂体的几何形态、连通性、以及储层非均质性,准确判断出砂体的成因类型,揭示了砂体内部建筑结构特征。进而适应高含水后期油田调整挖潜和三次采油的需要。According to the idea of analytical hierarchy process, using structure element analytical method combining outcrop studies, for anatomizing in-layer short lap, to study in detail Shengli oil field fluvial facies sand body internal building structure, the complete set reservoir bed can be divided in to single sand bed at highly asymmetrical longitudinal direction and described to microfacies and single sand body at flat. As a resuh, geometry, connectivity and reservoir heterogeneity of single sand body can be described predictably, genetic type be estimated accurately and character of sand body internal building structure be revealed , as well as, the study adapted the requirement of adjusting exploitation and tertiary oil recovery of later-high water-cut period oil field.
