Abstract

Inspired by the development of shale gas and the decrease of natural gas price, the investors kicked off shale oil exploration and development. U. S. A has been obtained huge benefit from shale oil, and the shale oil resource potential is also huge in China. Based on the previous study on shale oil resource potential of basins in eastern China, the comparative study on geochemical characteristics of shale oil between U. S. A and China has been done. The research results indicate that the oil saturation index（OSI） can be used as an effective index for judging the shale oil intervals, combined with the carbonate mineral content, brittle mineral content and the interbed. The results also show that the OSI values of Jiyang Depression are similar with that of Monterey, Barnett and Eagle Ford shale. At present, the shale oil exploration of China should be aiming at the hybrid type.

Key words： pore evolution; quantitative simulation; Chang₈ oil reservoir set; Ansai area
