摘要
火山岩是一种不多见的储集岩类型。本文根据岩心和薄片分析讨论了流状熔岩(即熔岩流)的岩相特征。并且指出在一典型的流状熔岩层中,顶部岩流自碎角砾状熔岩、上部和下部气孔状、杏仁状熔岩三个微相是有利储集层,而致密块状熔岩微相不能作为储层。
Volcanic rock is one of the reservoir rocks,difficult to discover.This paper discusses the litho-facies characteristics of lava (one group of volcanic rocks) from the observation of cores and sections.The study shows that in a classical lava bed the microfacies of the top self-breaking lava,the upper and lower vesicular and amygdaloidal lava are the favorable reservoir rocks for oil and gas.But the massive lava in the middle of the bed is nonporous and holds no fluid.
