摘　　要：辽河坳陷潜山勘探在经历了规模探索、研究、实践的基础上,提出了变质岩内幕油气藏的概念,建立了变质岩内幕油气成藏理论,有效指导了勘探工作,但是,随着勘探程度的不断深入,提出了许多需要进一步深化研究的内容。文中认为,在潜山以源-储双因素耦合为主导构成的有效运聚单元内,不同潜山受储层、输导条件影响,形成不同成藏特征的新生古储型油气藏。因此,需要对潜山类型进行划分,明确各种类型潜山油藏的分布特征,从而建立适用不同类型潜山的勘探思路。On the basis of large-scale exploration,research and practice,the concept of metamorphic rock has been summarized and put forward for the exploration of Liaohe buried hills.The theory of metamorphic rock interior hydrocarbon accumulation has been formed.Within the process of exploration,it has also been revealed that further research is necessary.In this paper,the idea has been presented that with the influence of reservoirs and transporting conditions for different buried bills ＂new source and old reservoir＂ type reservoirs with different accumulation characteristics have been formed in the effective transporting and accumulating units of buried hills,dominated by the source-reservoir double-factor coupling.Therefore,it is necessary to divide buried hills into different types and pinpoint distribution characteristics of various buried hill reservoirs so as to establish appropriate exploration methods for different types of buried hills.
