摘　　要：准噶尔盆地西北缘石炭系-二叠系发现了一批火山岩油藏,成为油田勘探开发中不可忽视的目的层之一。利用大量岩心分析、开发动态、钻井、测井、试油等资料,对火山岩相及储层特征进行了研究,结果表明准噶尔盆地西北缘火山活动严格受断裂控制,火山岩沿断裂两侧分布,火山岩岩性受火山喷发方式和火山岩相的控制。火山岩储层的形成经历了长期演化,是在构造、风化、蚀变作用等多种因素的影响下,形成的以多种成因孔隙和裂缝为储集空间的复杂储集层。A number of volcanic-rock reservoirs were found in the Carboniferous-Permian system in the northwestern margin of Junggar Basin,they were one of the targets and assignable strata for oilfield exploration and development.By using a large number of data of core analysis,dynamic development data,well drilling,well logging and oil test data,the volcanic-rock facies and reservoir characteristics were studied.The results show that the volcanic activity is strictly controlled by faults in the northwest of Junggar Basin,volcanic rocks are distributed along the both sides of the faults and the lithology of volcanic rocks is controlled by the modes of volcanic eruption and volcanic facies.The formation of volcanic-rock reservoir has experienced a long-term evolution.Influenced by structure,weathering and erosion,the complex reservoirs with pores and cracks of the various causes of reservoir space are formed.
