摘要
平南地区构造样式与平湖构造带上其他以断块构造为主的区块存在明显的差异,不但断块构造不发育,其他类型的构造亦不发育。要在平南地区获得突破,目前只能寄希望于与火成岩有关的圈闭。综合地震资料和地质资料分析了平南地区火成岩体的时空分布特征,对与火成岩有关的圈闭作了比较详细的研究。认为该区与火成岩有关的圈闭主要是火成岩联合断层形成的,并且圈闭与排烃在时空上具有良好的配置关系,有利于形成规模较大的油气藏,这对缺少圈闭的平南地区的油气勘探具有重要的意义。
Pingnan area lacks faulted blocks and other structural stylers, which differs from other sections in Pinghustructural zone where faulted-blocks were rich. To make breakthrcugh in petroleum exploration in such an area,people pin their hopes on traps related to igneous rocks. This papcr studied the distribution of the igneous rocksand traps related to igneous rocks on seismic and geologic data. It was concluded that traps that were related toigneous rocks were formed by the combined action of faults and igneous rocks. The traps were well associatedwith the expulsion of hydrocarbon in time and space, which was favorable for the formation of large-scale hydro-carbon reservoir.
