摘要: 准南前陆冲断带具有丰富的油气资源,但与资源评价关系密切的烃源岩研究不足。本文应用地球化学分析方法,对准南前陆冲断带的上二叠统、中下侏罗统、下白垩统和古近系等4套烃源岩的有机质丰度、有机质类型、热演化程度进行了系统分析和综合对比。结果表明,上二叠统烃源岩和中下侏罗统烃源岩为良好的烃源岩,古近系安集海河组其次,下白垩统烃源岩相对较差。

Abstract: Four successions of the source rocks including the Upper Permian,Middle-Lower Jurassic,Lower Cretaceous and Palaeogene strata are developed in the Huainan foreland thrust zone in which prospective oil and gas resources are hosted.The comparison of abundance,type and thermal evolution of the organic matter from the above-mentioned strata shows that the Upper Permian and Middle-Lower Jurassic strata are the best source rocks,followed by the Palaeogene Anjihaihe Formation.The Lower Cretaceous source rocks are less prospective.
