摘　　要：准噶尔盆地中拐凸起石炭系火山岩历经近40年的油气勘探未发现规模油气藏,问题的关键是未能有效预测火山岩储层发育带。为此,融合多种技术,在地震资料精细处理解释的基础上,准确预测了该区火山岩储层发育范围;通过地震属性、相关分析刻画火山岩有利储层平面展布规模;利用地震相特征刻画火山岩各类型圈闭;结合地震反演技术,确定火山岩有利储层的纵向规模。在预测结果指导下完钻的探井在石炭系均获得了高产工业油流。In Zhongguai Uplift of west Junggar Basin,large scale of oil and gas reservoirs of Carboniferous volcano res-ervoir have not been found in nearly 40 years of oil and gas exploration.Therefore,based on the fine processing and inter-pretation of seismic data,combined with many technologies,it was accurately predicted the development range of volcano reservoir in this area.Using seismic attributions and correlation analysis,the plane distribution scale of the favorable volca-no reservoirs was characterized.Using the characteristics of the seismic facies,various kinds of volcano traps were por-trayed.Finally,the vertical scale of volcano reservoir was determined by using the seismic inversion technologies.The fore-cast results showed that the drilled wells have obtained good industrial oil flows in Carboniferous system.
