摘要

随着油气勘探和研究工作的深入，发现油气藏的类型日益丰富，弄清不同类型油气聚集的概念内涵、外延和类属，是开展深入研究和应用的基础。详细讨论了岩性油气藏、地层油气藏的内涵和属类，及其与连续型油气聚集的区别，指出了源外的连续型油气聚集必须具备大面积非常规（致密）储层、广覆式优质烃源岩和“源—储”上下紧密叠置、无缝对接这3条充分必要条件，以及圈闭形成条件和渗流聚集方式2项鉴别标志（本质属性）。

Abstract

Understanding the concept including connotation and extension and category for different hydrocarbon accumulations is fundamental for further study and application,with the development of petroleum exploration and research work,and the increasingly enriched types of discovered reservoirs.In this paper,we discuss the concepts and category of lithological and stratigraphic accumulations,and the distinctions from continuous-type accumulation as well.We come up with three sufficient and necessary conditions for continuous hydrocarbon accumulation outside the source extent,that is,an unconventional (tight) reservoir,a wide-distributed high-quality source rock,and a configuration that the reservoir should overlap the source rock tightly and seamlessly.In addition,there are two identification markers,namely the essential attributes in terms of trap-forming conditions and percolation and accumulation mode.

Key words： Oil-gas reservoir; Petroleum accumulation in lithological trap; Petroleum accumulation in stratigraphic trap; Unconventional petroleum; Continuous petroleum accumulation; Connotation and extension of concepts; Identification marker; Essential attribute.
