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 volcanic reservoirs of Carboniferous in Xiquan area of Junggar Basin are characterized by smallscale volcanic body, and the main controlling factors are not clear. On the basis of core observation and thin section identification, combined with logging, analysis and test data, a statistical analysis of the lithologies of Carboniferous in Xiquan area was carried out. The main controlling factors of reservoir physical properties and its distribution law were analyzed. The results show that the lithology in the southern structural belt is mainly composed of andesite, volcanic breccia and tuff, and mainly tuff, sedimentary rock and andesite in the northern structural belt. The reservoir properties in the southern structural belt are obviously better than that in the northern structural belt, of which the main controlling factors are lithology, lithofacies, tectonic movement and weathering leaching. The volcanic facies, such as volcanic breccia and tuff in the southern structural belt, the overflow facies of andesite in the northern structural belt, and their overlap zones with the structure highs and the fracture development, are favorable plays for hydrocarbon exploration.

Key words: lithofacies types, sedimentary model, tide, shelf sand ridge, Pinghu Formation, Xihu Depression
