摘要: 巴什托构造主要形成于海西期,海西晚期时巴什托构造石炭-二叠系中有油气富集成藏、喜山期的快速沉降在巴什托构造古油气藏基础上形成了流体压力封闭箱,本文叙述了流体压力封存箱的发育特征、成因及油气意义.Abstract: Bashituo structure developed mainly in Hercynian period. Hydrocarbon enriched and oil(gas) accumulation formed in Carboniferous and Permian in Bashituo structure during late Hercynian. Rapid subsidence during Himalayan period resulted in a fluid pressure compartment on the basis of paleo -accumulation in Bashituo structure. This paper describes the development features and genesis of the fluid pressure compartment and its significance in oil and gas exploration.
