摘　　要：准噶尔盆地三南-滴水泉凹陷在石炭纪处于持续凹陷沉积状态,地震地质解释研究认为,区内上石炭统发育了上火山岩序列、沉积岩层和下火山岩序列。沉积岩层内发育了良好的烃源岩,与下石炭统滴水泉组的烃源岩一起构成了石炭系天然气成藏的主力气源岩。通过对石炭系发育状况及结构、天然气成藏的生储盖条件、资源量估算和成藏模式分析,认为上、下序列火山岩层是良好的石油天然气储集层,位于三南-滴水泉凹陷及其周缘地区的石炭系火山岩层系,天然气资源量蕴藏巨大,具有良好的石油天然气勘探前景。Sannan-Dishuiquan sag in Junggar basin has been occurred in continental depressed and sedimentary status in Carbonifemous period. The seismic geologic interpretation shows that upper volcanies sequence, sedimenlary rock and lower volcatics seqtunee arm developed in Upper Carboniferous in this area. And good source rock developed in the sedimenlary rock consitules the major gas source rocks of Upper Carboniferous gas reservoir in this area together with Dishuiquan source rock of Lower Carboniferous.This paper presents the studies of the Carboniferous occurrence source-reservoir-cap rock conditions of gas reservoir, resource amount assessment and petroleum accumulation model. It is indit.ated thai the upper and lower sequences of volcanic rocks in lhe studied area are all good oilgas reservoirs. The Carboniferous volcanic rocks in Sannan-Dishuiquan sag and its adjacent areas are of good prospects for petroleum exploration, with massive gas resources, being as favorable targets for gas exploration in Junggar basin.
