A great of subaqueous fan sand bodies developed in Shuangyang Formation in Moliqing Fault Depression, Yitong Basin. Based on core observation, thin section analysis and physical property statistics, it is indicated that the subaqueous fan reservoir belongs to low-porosity, ultra-low permeability and thin throat reservoir. The reservoir space types are mainly primary intergranular pore and secondary erosion pore. The rock types are mainly feldspathic litharenite and lithic arkose. The physical property of middle fan reservoir is better than outer fan. According to the reservoir evaluation result, it is shown that the favorable reservoir mainly distributed in the southwest of Kaoshan Sag and in the northeast of Jianshan bulge. The subaqueous fan sand bodies in these areas have good potentials for oil and gas exploration.
