摘　　要：本文在总结前人研究的基础上,结合胜利及辽河油田最新资料,提出了一种火山岩油气藏储层分类方案,共分为火山熔岩型、火山碎屑岩型和潜火山岩型3种类型。其中火山碎屑岩型又可分为正常火山碎屑岩型和火山碎屑沉积岩型两种亚类型;潜火山岩型分为隐爆角砾岩型和蚀变岩型两种亚类型。文中结合实例对各种类型储层的成因机制、空间展布特点以及储集性的变化特征进行了阐述和讨论。A classification of oil and gas reservoir beds of volcanic rocks is put forward on the basis of existing data and the latest materials in the Shengli and Liaohe Oil Fields. Reservoirs of volcanic rocks are mainly classified into three types-, lava reservoir, pyroclastic reservoir and sub-volcanic reservoir. The pyroclastic reservoirs can be further divided into two sub-types: the normal pyroclastic reservoir and the sedimentary pyroclastic reservoir; and the sub-volcanic reservoirs can be further divided into two sub-types: the breccia reservoir and the altered invasive reservoir. Some examples are discussed to illustrate the different reservoirs, and the characteristics of these reservoirs are summarized.
