摘　　要：准噶尔盆地西部隆起中拐凸起石炭系被断裂分割为不同断块油藏,具有不同的油水界面,均为受断裂控制的带底水的块状油藏。厚层状火山岩体,裂缝发育,双重介质,油水关系复杂;火山角砾岩及熔岩均可成为良好的火山岩储集体。钻探显示,整个中拐凸起石炭系普遍含油,古隆起高部位油气更为富集,是目前有利的勘探领域。结合火山岩岩性岩相展布特征,剖析了火山岩喷发模式及其分布规律及主控因素,提出了裂缝式火山喷发模式、其分布主要受控于火山口及古地貌。Zhongguai Uplift carboniferous in the western Junggar Basin was segmented by fault into different fault block reservoirs with different oil-water interfaces,which are all massive reservoirs with bottom water controlled by faults. In addition,the thick layered volcanic rock mass,the crack development,the dual medium,the complex oil-water relationship,the volcanic rock and the lava can all become good volcanic reservoir bodies. The drilling showed that the whole Zhongguai Uplift carboniferous system is generally oil- bearing,and the oil and gas in the high part of the paleo uplift is enriched,which is a favorable exploration area. With the combination of volcanic rock lithology and lithofacies distribution characteristics,it was analyzed on the volcanic eruption pattern,its distribution and main controlling factors. The fissure type volcanic eruption pattern was proposed,of which distribution was mainly controlled by the crater and paleo geomorphology.
