摘　　要：利用岩心、薄片、测井等资料,综合分析三塘湖盆地条山凸起二叠系条湖组火山岩储层特征及控制因素,研究结果表明:基性玄武岩是本区二叠系条湖组主要的火山岩储集岩类,储层以裂缝-孔隙型为主,储集空间以次生杏仁体溶孔、斑晶溶孔为主,次为残余气孔、基质晶间溶孔、残余构造缝和扩溶缝。储层物性主要受控于火山岩的岩性岩相、溶蚀和矿物充填作用、构造裂缝及古地貌形态4个因素。This paper deals with reservoir characteristics of volcanic rock reservoir and the main affecting factors of reser- voir physical property in P2t of Tiaoshan uplilt,Santanghu basin,based on observing of drilling cores and rock thin section andlogging.The results indicate that basalt are main reservoir rock types,fraetured-pore reservoir are the reservoir type, the types of pores include mainly amygdala solution pores,dissolution Pores in inset,and then residual air Pores,in-ter- crystal pores in matrix,residual seam,Karst seam.Physical properties of the reservoirs are mainly controlled by Volcanic rock lithology and lithofacies,dissolution and mineral filling,Structural fractures and paleogeomorphy.
