摘　　要：含油气系统(PS)作为一种研究对象、研究思路和研究方法,是常规油气勘探评价的重要手段之一,但对非常规油气研究却有一定的局限性。为了探寻源内非常规油气勘探评价研究思路和方法,在回顾含油气系统概念发展历程的基础上,对比分析了烃源岩体系和非烃源岩体系油气特征和差异,形成了一套适合于源内滞留烃准连续—连续聚集型油气藏的研究思路和研究方法,提出了烃源岩层系含油气系统(SRPS)概念,论证了其研究思路、研究内容及基本内涵,总结了4项研究关键技术。研究成果丰富了源内非常规油气勘探评价理论体系,为源内非常规油气勘探评价提供了指导。Petroleum system(PS),as a research object,research idea and research method,is one of the important methods for conventional oil and gas exploration and evaluation,but it has some limitations on the unconventional oil and gas research.In order to explore the research ideas and methods of in-source unconventional oil and gas exploration and evaluation,on the basis of the review of the development history of petroleum system concept,the characteristics and differences of oil and gas in the hydrocarbon source-rock system and non-source-rock system are contrasted and analyzed,thus a set of the research ideas and methods suitable for the quasi-continuous and continuous accumulation of retained hydrocarbon inside source were established,and the concept of source rock-series petroleum system(SRPS)was proposed,the research ideas,contents and basic connotation of the SRPS were demonstrated,and four key technologies were finally summarized.For the in-source unconventional oil and gas exploration and evaluation,the research results not only enrich its theoretical system but also provide the guidance for it.
