摘要: 从目前勘探现状来看,渤海湾(陆上)盆地属于油气勘探的成熟盆地,但资源量的研究表明,目前探明储量为85亿多吨,与总资源量190亿t相距甚远,探明程度仅为45%.以往的勘探工作集中于下第三系沙河街组地层.文中探讨了渤海湾盆地下第三系烃源岩的分布在纵向和横向上与油气成藏的联系,渤海湾盆地构造演化过程与油气成藏的关系,以及渤海湾盆地更深层次下古生界地层的烃源岩成藏的可能性,提出了“普查浅层,滚动中间(下第三系),探索深层”的勘探战略.

Abstract: From the current exploration situation,Bohai Bay Basin belongs to exploration muture basin.Till now,8. 579 billion tons has been proved in Bohai Bay Basin.But according to the analysis of resources estimation,overall amount of resource is about 19 billion tons.The proved rate is only 45%.Therefore,there is much work left to do. Now exploration is mainly focused on Shahejie Formation in Paleogene.This paper will discuss the relationship of Paleogene source rock with hydrocarbon trap,the relationship of tectonic evolution with hydrocarbon trap and the possibility of oil and gas trap in the deep source rock (including Paleozoic).The exploration strategy in Bohai Bay Basin should be "checking up any information in the upper layer(Neogene),progressive exploration and develop-ment of middle layer(Paleogene)and exploring the deep layer(Paleozoic)".

Key words: Bohai Bay Basin, source rock, oil and gas trap, exploration strategy
