| 摘 要： | 川西坳陷西南端,在雅安周公山构造钻获玄武岩气藏以来,对玄武岩的研究引起石油地质工作者的极大重视。经实地踏勘及研究认为:玄武岩主要分布在三大古陆及其前缘,可分为海相喷发、陆上喷发和先海相后陆相的三类环境。据火山构造可分为火山岩的相划分则是溢流相、爆发相、火山颈相、火山沉积相和次火山岩相,中心式喷发及裂隙式喷发等,进而可识别出火山岩的相划分则是溢流相、爆发相、火山颈相、火山沉积相和次火山岩相等。从油气储集条件考量与火山颈相关的溢流相较为有利;若与烃源配置适当则可形成玄武岩油气藏。

| Abstract: | Preliminary study indicates that the Permian basalt at the southwestern end of the west Sichuan depression may be divided into marine,continental and marine-continental alternating eruptive facies or into overflow,explosive,neck,volcanic-sedimentary,and subvolcanic facies.The overflow facies related to the neck is favorable for petroleum reservoir. |
