摘　　要：为识别徐家围子地区火山岩微相类型 ,研究火山岩储层的微观结构特征、储层类型及储层参数 ,以岩心资料、试气成果、测井资料为基础 ,对火山岩储层特征进行了深入研究。其结果 :本区火山岩储层可划分为流纹岩、安山岩两类 ;建立了不同类型储层的有效孔隙度计算方法和有效厚度划分标准。这一成果对本区火山岩气藏的勘探开发具有一定的指导作用。In order to identify microfacies of volcanics in Xujiaweizi area, volcanic reservoirs were studied in terms of micro structure, reservoir type and parameters based on data of coring, gas testing and logging. The result was that volcanics of this area could be divided into rhyolite and andesite; effective porosity calculation method and effective thickness division standard were established for different reservoirs. This achievement may guide the exploration and development of volcanic gas reservoirs in this area.
