| 摘 要： | 随着非常规油气资源工业化勘探开发的快速发展,非常规油气地质学理论体系逐步建立,迫切需要创新构建非常规油气沉积学理论。通过简要概述非常规油气沉积学的基本内涵,提出“非常规油气沉积学”的概念,综述我国四川盆地页岩气、鄂尔多斯盆地致密油与页岩油等典型非常规油气层系沉积学研究进展,并展望非常规油气沉积学研究所面临的关键科学问题与挑战。研究指出非常规油气资源沉积富集与重大地质环境突变密切相关,是全球性或区域性构造与海（湖）平面升降、火山活动、气候突变、水体缺氧、生物灭绝与辐射、重力流等多种地质事件沉积耦合的结果。未来需要从地球系统科学出发,采用“非常规思想”,以地质事件分析思维深入开展非常规油气沉积学研究,为寻找非常规油气资源发挥重要作用。

| Abstract: | The theoretical framework of Unconventional Petroleum Geology has been gradually established along with the rapid progresses in exploration and development of unconventional petroleum resources. It is now imperative for innovative new insights into the unconventional petroleum sedimentology. Herein, the concept and scientific connotations of “Unconventional Petroleum Sedimentology” are proposed and briefly introduced. The research progresses are summarized for the sedimentology of typical unconventional petroleum resources in China, such as Wufeng-Longmaxi Shale gas in Sichuan Basin and tight oil and shale oil of Yanchang Formation in Ordos Basin. Further research themes and challenges of Unconventional Petroleum Sedimentology are discussed. Sedimentary enrichment of unconventional petroleum resources can be closely related with some critical environmental changes, which would be the result of coupling sedimentology from several geological events such as global or regional tectonic activities, sea (lake) level changes, volcanic eruptions, climate changes, anoxic bottom water, biotic mass extinctions and radiations, and gravity currents. For better understanding of Unconventional Petroleum Sedimentology in future, the Earth Systems Science view and “unconventional” insights should be applied to its research by analyzing geological events in details, which can play an important role in the discovery of new unconventional petroleum resources. |
