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。

Abstract: Sannan-Dishuiquan sag in Junggar hasin has heen ocurred in continental depressed and sedimentary stalus in Carboniferous period. The seismie geologic interpretation shows thal upper voleanics sequence. sedimenlary rock and lower volranics sequenee ar developed in Upper Carboniferous in this area. And god! soure rork developed in the sedimentary rock ('onstituters the major gas sourve rocks of Upper Carloniferous gas reservoir in this area together with Dishuiquan source rock of Iower Carboniferuus. 'This paper presrents the studies of the Carboniferous ocurrence. source-reservoir-cap rock conditions of gas rservoir. resoure amnou ssessent and petroleum accunulation model. It is indiraterd that the upper and lower sequencrs of voleanir rocks in the slusdied arera are all gonxd oil-gas reservoirs. The Carboniferous voleanic rourks in Sannan-Dishuiquan sag and is adjacent areas are of gond prsperts for petroleum exploration. with massive gas resourees. being as favorable largets for gas exploration in Junggar basin.

Key words: Junggar basin, Carboniferous, stratum, volcanic rock, natural gas, petroleum accumulation model
