摘要
在对三塘湖盆地不同层系生油岩研究的基础上，重点分析了二叠系生油岩和侏罗系原油的地球化学特征，采用生物标志物多因素对比、甾萜化合物指纹对比、稳定碳同位素类型曲线对比等方法进行了油源对比。研究表明，侏罗系原油的组成特征与侏罗系生油岩抽提物的组成特征差别较大，两者无亲缘关系，而与二叠系生油岩抽提物化学组成比较接近，且有较好的对比关系。这说明侏罗系原油来源于二叠系的生油岩。
Oil and gas flow (or oil and gas shows) has been found in sandstone of Xishanyao formation of Middle Jurassic series at Santanghu Basin. In order to reveal the source of oil and gas, the geochemistry characteristics of Jurassic and Permian source rocks and Jurassic oil are analyzed. Oil to source correlation was made by the use of varied geochemistry methods, such as biomarker multi factor correlation, steroid and terpenoid finger print correlation, stable carbon isotope correlation etc. The Jurassic oil in Santanghu Basin mainly came from Permian source rocks.
