Abstract: Based on the plate of lithofacies, log factes and sedimentary factes, the fan-delta of the third member of the Shahejie Formation in Gaoshangpu oil field could be divided into 9 natural gamma curve shapes and assemblages (M), 8 rock types (N). This constitutes M/N type of log factes so as to demonstrate different kinds of sand bodies. The dipmeter data from two wells were used to distinguish channel sand body represented by large red mode, sand bar represented by large blue mode and distal sheet sand body of small blue or green mode through arrow plot of short correlation. The results sho that the stretch directions of sand bodies are coincident with that of paleocurrent,the water depth was less than 15 m during deposition.
