摘　　要：综合运用有机岩石学、有机地球化学等方法,以井下暗色泥岩的分析资料为主,研究和分析了鄂尔多斯盆地西缘石沟驿地区下二叠统烃源岩的有机质生烃特征和沉积环境。研究结果表明:太原组、山西组暗色泥岩和煤为二叠系主要的烃源岩层系,有机质类型以Ⅲ型为主,早二叠系烃源岩已不同程度地进入成熟—高成熟阶段。Comprehensively applying the organic petrology method,organic geochemical method and other methods,and taking the analysis data of underground dark mudstone as main sources,this paper researches and analyzes the hydrocarbon-generating features and depositional environment of the organic matters contained in Lower Permian System in Shigouyi Area on the western margin of the Ordos Basin.The research results show that that the dark mud-stones and coals in Taiyuan and Shanxi Formations are main hydrocarbon source rocks,most of the organic matters are typeⅢ,and the hydrocarbon source rocks in Early Permian have come into the maturity to higher maturity stage to some extent.
