根据汪家屯侏罗系火山岩储层的岩心资料、测井资料对其岩性、物性及测井响应特征做了较全面的分析，指出该区火山岩储层岩性按成因可划分为熔岩、火山碎屑岩和过渡岩；储层物性属低孔、低渗型，储集空间孔隙占总面孔率的９０％以上，裂缝不足５％，但对各种孔隙却起到连通作用；测井响应中的密度、自然伽马、自然能谱可将该区的安山岩、流纹岩和凝灰岩很好的区分开；利用电阻率成象、声波成象及倾角资料处理可识别裂缝；同时发现该区火山岩测井响应的密度值与孔隙度之间具有很好的相关性
According to the core data and log data of the Juji volcanic reservoir in Wangjiatun, the lithology, physical properties and logging response characteristics are comprehensively analyzed. It is pointed out that the lithology of volcanic reservoirs in this area can be divided into lava and volcano The reservoir properties belong to low porosity and low permeability. The pores in the reservoir space account for more than 90% of the total porosity and less than 5% of the fractures, but play a communicating role for various pores. In the well logging response The density, gamma ray and natural energy spectrum can distinguish the andesite, rhyolite and tuff in the area well. The resistivity imaging, acoustic imaging and dip data processing can be used to identify the cracks. At the same time, the volcanic rocks There is a good correlation between well log response density and porosity
