摘　　要：三塘湖盆地火山岩孔隙结构极其复杂,多具非均质性强、构成多元化和分选差的特点,结合岩心观察等资料,提出了三塘湖地区火山岩孔隙结构类型的划分依据,进行了分类划分,且提出了在压力设置和针对火山岩排驱压力取值等方面的见解。Pore structure of volcanic rock in Santanghu basin is very complex, with characteristics of serious anisotropy, multiple constituents and poor gradations. Combined core observed data, classification criteria about types of pore structure of volcanic rock in Santanghu is raised, and its classifications are carried out. Based on t study and analysis for the various data, the opinions about pressure setting and the taken value of displacement pressure of volcanic rock are given.
