| 摘 要： | 南堡凹陷油气资源丰富，古近系主要分布有沙三段、沙一段和东三段三套有效烃源岩。在层序地层学研究的基础上，应用有机地球化学、有机岩石学和沉积有机相等研究手段和方法对东三段、沙一段和沙三段不同层序和同一层序不同体系域中烃源岩特征进行综合研究。结果表明，南堡地区烃源岩非均质性特征明显，烃源岩生烃的层位主要分布于SQ9、SQ5~SQ8、SQ2和SQ1的湖扩展体系域和早期高位体系域，SQ2为优质烃源岩段。造成这种非均质性的主要原因是不同体系域的沉积特征，这影响着烃源岩有机质类型和保存条件。

| Abstract: | Nanpu Sag is rich in oil and gas and the main hydrocarbon source rocks of the Eogene are distributed within Es3,Es1 and Ed3 Formations. Based on the sequence stratigraphy study, the hydrocarbon-generating potential and distribution of source rocks in the Eogene sequence stratigraphic framework of Nanpu sag are discussed in this paper by the methods of organic petrology, geochemistry and organic facies. The results show that the heterogeneity of source rocks varies in different systems tracts. The hydrocarbon source rocks which were deposited in the early highstand systems tract and extent systems tract have the best hydrocarbon-generating potential in the SQ9, SQ5-SQ8, SQ2 and SQ1 of Eogene, because the characteristics of sedimentation in the different systems tracts affect the type and conservation of organic materials in source rocks. |
