Abstract: 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 result, 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.
