摘　　要：车排子地区位于准噶尔盆地西北缘南段,紧邻生烃凹陷,长期处于油气运移的有利指向区,该区石炭系火山岩非常发育。石炭系烃源岩无生烃能力,其油源主要来源于二叠系风城组和乌尔禾组;储层多发育在物性较好的火山角砾岩或玄武岩中,被致密的火山岩或泥岩所覆盖;车排子石炭系火山岩油气藏主要受断裂、岩相和不整合面的控制,表现为受构造控制的两期成藏,一期调整。Chepaizi Area was located in the south of northwestern margin of Junggar Basin,which was adjacent to the depression of hydrocarbon genesis,it was a beneficial area oil and gas migration for a long period,where Carboniferous volcanic rocks were well developed. Hydrocarbon genesis was not capable in the Carboniferous volcanic rocks,the oil and gas of volcanic reservoirs mainly came from Fengcheng Formation and Wuerhe Formation of Permian system. Reservoirs were mainly volcanic breccic or basalt with good physical properties,and it was covered by dense volcanic rocks or mudstones. The volcanic hydrocarbon reservoirs are controlled by fracture,lithofacies and unconformity. Hydrocarbon accumulation is controlled by twice accumulation and once adjustment of tectonic movement.
