摘　　要：深层火山岩油气藏具有不同于沉积岩油气藏的特殊形成环境和自身的特殊风格与分布规律：高温高压环境；储集层性能好于碎屑岩储集层，且与火山岩厚度呈负相关；储集层的孔隙度、渗透率受埋藏深度的影响较小；油气藏主要受岩性因素控制，最有利的油气聚集带（区）位于火山岩向沉积岩的变薄尖灭带。深部火山岩油气藏的这种分布规律，对于寻找类似的油气藏是可以借鉴的。： Deep－buried volcanic reservoirs， which are different from sedimentary reservoirs， are characterized by special formation environment and distribution： with high temperature and high pressure． Volcanic reservoirs， which are inversely correlated with the thickness of volcanic rocks， have better reservoir properties than the clastic reservoirs， and the porosity and Permeability of reservoirs are less influenced by their buried depth． These reservoirs are predominantlycontrolled by lithological factors， with the most favorable hydrocarbon accumulation zone located in the thinning belt of volcanic rocks towards sedimentary rocks． Undoubtedly， such distribution peculiarity of deep－buried Volcanic reservoirs can contribute to the discovery of similar reservoirs．
