摘　　要：为了解新疆哈拉哈塘-新垦地区二叠纪火山岩下伏的油气储层位置及构造形态,从野外地质资料及钻井资料出发,结合测井-地震剖面数据,对二叠纪火山岩喷发期次、火山岩相进行了详细研究。结果表明,研究二叠纪火山岩喷发分为3个期次,火山岩相类型分为四种:(1)空落相;(2)火山喷发沉积相(3)火山碎屑流相;(4)溢流相。能够对下伏油气储层位置及构造的圈定提供一定依据。To understand the Permian volcano rocks underlying oil and gas reservoir location and structure in Xinjiang Halahatang-Xinken area. Based on field geological data and drilling data, combined with log seismic profile data, the eruption stages and volcanic lithofacies of Permian volcanic rocks are studied in detail. The results show that the eruption of Permian volcanic rocks can be divided into three stages, volcanic facies types are divided into four types： （1） empty facies; （2） volcanic eruption sedimentary facies; （3） pyroclastic flow facies; （4） overflow facie. It can provide certain basis for delineating the location and structure of underlying reservoirs.
