【摘要】：准噶尔盆地西泉地区石炭系火山岩油藏中的火山岩体单个规模较小,平面展布形态缺乏规律性,储层主控因素不明朗。在岩心观察、薄片鉴定基础上,结合测井、录井、分析化验及试油等资料,对西泉地区石炭系的岩性进行了统计,对储层物性的主控因素及其平面展布规律进行了分析。结果表明:西泉地区南部构造带岩性以安山岩、火山角砾岩、凝灰岩等为主,北部构造带岩性以凝灰岩、沉积岩、安山岩等为主。南部构造带的储层物性明显好于北部构造带,其控制因素主要有岩性和岩相、构造运动、风化淋滤作用等。南部构造带的火山角砾岩、凝灰岩等喷发岩相,北部构造带的安山岩等溢流相以及它们与构造高点、裂缝发育的叠合区是油气勘探的有利区带。
[Abstract]:The single scale of volcanic rock in Carboniferous volcanic rock reservoir in Xiquan area of Junggar Basin is relatively small the plane distribution pattern is lack of regularity and the main reservoir control factors are not clear. On the basis of core observation and thin section identification, combined with logging, analysis and testing data, the lithology of Carboniferous system in Xiquan area is statistically analyzed, and the main controlling factors of reservoir physical properties and their flat distribution law are analyzed. The results show that the lithology of the southern structural belt in Xiquan area is mainly composed of andesite volcanic breccia tuff and so on. The lithology of the northern tectonic belt is dominated by tuff sedimentary rock andesite and so on. The reservoir physical property of the southern structural belt is obviously better than that of the northern tectonic belt, and its controlling factors are mainly lithology and lithofacies, tectonic movement, weathering and leaching, etc. The volcanic breccia, tuff and other eruptive lithofacies in the southern tectonic belt, andesite overflow facies in the northern tectonic belt and their high points are favorable zones for oil and gas exploration.
