Pore fluid is an important tool to study hydrocarbon accumulation. Through the analysis of geochemical properties of crude oil in Shawan Formation of Dushanzi anticline, it is proven that the hydrocarbon came from lacustrine shale. According to the subsurface water, in the vertical, the connectivity of the upper sandstone is better than that of the lower sandstone, and in the horizon, the distribution of sandstone is controlled by the sedimentary microfacies. The oil in Dushanzi came from Lower\|Middle Jurassic, and then reached Shawan Formation through Dushanzi reverse fault. The distribution of source rock and the development degree of reservoir are the main factors to control hydrocarbon accumulation. Lithologic hydrocarbon reservoirs may be found in the lower members of Shawan Formation.
