辽东湾地区烃源岩生物标志物特征与油源对比
Biomarker characteristics of source rocks and oil-source correlation in Liaodong Bay
摘要
Abstract
Using the parameters of source rocks and biomarker, the oil genetic types and distribution characteristics were divided and discussed by oil-source rock correlation based on effectively discriminating three source rocks. The results show that the three source rocks have different biomarker assemblages. The first member of Shahejie fonnation(Es, ) can be distinguished from other two source rocks by higher gammaeerane-C30 hopane ratio, higher ETR of (C28 +C29) / ( C28 + C29 +Ts ) and lower hopane-sterane ratio. The third member of Dongying formation ( Ed,) can be distinguished from the third member of Shahejie formation(Es3) by higher C19/C23, tricyclic terpane, higher C24 tetracyclic terpane-C26 tricyclic terpane ratio and lower 4-methyl sterane-CM sterane ratio. The differences on biomarker assemblages among the potential source rocks indicate that they had different parent material and formed in different sedimentary environment. Based on systematic oil-source correlation , two oil families derived from Es3 and Ed, source rock respectively, and the typeS of mixed oils derived from Es, and Es, source rock were identified. The mixed oil derived from Es, and Es, source rock is the most impotent oil genetic type, and occurs widely in sag and on uplift. Occurrence regions of Ed,-derived and Es,-derived oils are smaller and controlled by the thermal evolution condition of local source rocks.关键词
