Abstract: The research of Whole Petroleum System (WPS) theory, emerging as a frontier field in the petroleum and natural gas geology at present, has attracted extensive attention from both the petroleum industry and academic community since its proposal. Expanding beyond the traditional concepts of petroleum systems, the research of WPS theory involves the geological regularities and resource development of unconventional oil and gas, representing an evolution and development of the petroleum system theory. This paper elucidates the fundamental principles of WPS theory, and summarizes the research progress during its development, including:(1) research advances and exploration practices of the Permian WPS in Junggar Basin; (2) the differential enrichment in the sequential distribution pattern of conventional and unconventional oil and gas, as well as the hydrocarbon accumulation and enrichment mechanism controlled by "source-reservoir coupling"; (3) hydrocarbon migration models in WPS; (4) analysis of WPS in sedimentary basins with the development of multiple sets of source rocks; (5) research and development of the new-generation basin modeling technology and genesis-based hydrocarbon resource appraisal methods on the basis of WPS theory.

摘要： 全油气系统理论自提出以来受到了石油工业界和学术界的广泛关注,是当前石油天然气地质学的前沿研究领域。全油气系统理论不仅涵盖了传统油气系统概念,还扩展到非常规油气的地质规律与资源开发,是含油气系统理论的发展。对全油气系统理论的基本原理进行了阐释,并总结了全油气系统理论在发展过程中的研究进展,包括:①准噶尔盆地二叠系全油气系统的研究进展与勘探实践；②常规油气—非常规油气序列分布规律中的差异富集现象与“源-储耦合”控制下的成藏富集机理；③全油气系统中的油气运移形式；④发育多套烃源岩的沉积盆地的全油气系统分析；⑤基于全油气系统理论的新一代盆地模拟技术及成因法油气资源评价方法的研发。
