摘　　要：随着非常规油气资源勘探的日益发展及美国页岩气价格的下调,国内外掀起了页岩油勘探的热潮,美国已经取得了巨大经济效益,而我国同样也具有丰富的页岩油资源潜力。通过对我国东部湖相沉积页岩大量地球化学数据统计分析,并与美国页岩油已成功开发区块的地质、地球化学参数进行对比,综合认为采用OSI指标,并结合碳酸盐矿物、脆性矿物含量及薄夹层存在与否,作为初步判断页岩油发育层段的标志。结果表明,济阳坳陷沙三下亚段页岩OSI指标与Monterey,Barnett及Eagle Ford页岩的OSI指标较为接近,具有一定的页岩油、致密油潜力,建议当前国内勘探应瞄准混合型页岩油。Inspired by tile 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 tile 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.
