摘　　要：近年来,随着火山岩油气藏勘探开发取得突破性进展,火山岩储集层已经成为油气勘探的一个新领域。在调研了国内外火山岩油气藏储层研究成果的基础上,总结了火山岩储层的特殊性、储集空间类型及成因、储集空间的演化特征以及储集层类型。火山岩储层不具岩石类型的专属性,与沉积岩储层有着很大的差异。火山岩储集空间按成因可以分为原生孔隙、次生孔隙、原生裂缝、次生裂缝4大类,其形成与演化经历了原生形成阶段、风化淋滤阶段、浅埋成岩阶段、构造断裂阶段、深埋溶蚀阶段。最后指出了火山岩储层研究中仍然存在的一些问题,并且针对这些问题提出了今后的研究方向。In recent years,as the breaking through progress of the exploration and exploitation for volcanic rock reservoirs,the reservoirs have become new targets for exploration and exploitation.On the basis of studying the existing literatures on the reservoirs home and abroad,the particularity of the volcanic rock reservoirs,the types and the genesis of reservoir space,the evolution feature of the space and the types of reservoirs are summered.Volcanic rock reservoirs are not in some lithologies,there is huge difference between it and sedimentary rock reservoirs.The reservoir space of volcanic rock reservoirs can be grouped in to four types according to the genesis,i.e.,primary pore,second pore,primary fracture and secondary fracture,its formation and evolution underwent five stages,i.e.,primary formation stage,weathering leaching stage,shallow bury digenesis stage,tectonic faulting stage and deep bury dissolution stage.At last,it is pointed out that there still are some problems in volcanic rock reservoir research,and research approach in the future is presented aiming at the problems.
