| 摘 要： | 裂谷盆地是夭折的裂谷。在其所形成的伸展构造中蕴藏有丰富的石油及天然气。渤海湾盆地是典型的裂谷盆地,按其形成和发展可划分为五个阶段:即萌芽阶段;初成阶段;沉陷阶段;回返阶段及裂谷后沉陷阶段。这五个阶段的特征在深陷带地区表现最为明显,其中沉陷阶段和回返阶段对油气的形成及聚集关系最为密切。渤海湾盆地的构造演化、岩浆活动、断裂变动及油气的形成、运移、聚集等是一个有机整体不可分割的部分。它们有着内在联系及一定的规律性,对这方面进一步深入研究将会对油气勘探工作起着指导作用。

| Abstract: | A rift basin is a die young rift valley.There are rich oils and natural gases in its extensional structure.According to its formation and development,the Bohaigulf basin is a typical rift basin which can be divided into five stagesf: embryonic, initial, sinking,inversional and rift late sinking stages.The characteristics of the five stages are very clear in the deep depression belts,amony which the sinking stage and the inversional one are closely related to the formation and accumulation of oils and natural gases.In the Bohai gulf basin,the following respects-structural evolution,magmatic activities,faulting as well as the oil-gas formation,migration,accumulation etc.are an inseparable organic whole.They have internal relations and certain laws.The further investigation and study in this respect will play an important role in the exploration of oils and gases. |
