摘　　要：露头与室内资料显示,准噶尔盆地南缘米泉区块上二叠统与上三叠统烃源岩为好烃源岩,中下侏罗统烃源岩在凹陷中心总体可以达到中等好烃源岩级别。储集层整体上属低孔特低孔、低渗特低渗储集层,但侏罗系储集层物性相对较好,其次是三叠系储集层,再次是二叠系储集层。研究区存在3套有利的生储盖组合,成藏条件良好。与其他富油气区对比研究表明,米泉区块具有较大的油气勘探潜力。It is indicated by the outcrop and laboratory data that the source rocks in upper Permian and upper Triassic are good hydrocarbon source rocks in Miquan Block , and the source rocks in the middle and lower Jurassic are middle-good hydrocarbon source rocks in the central depression on the whole. The reservoir is a low and extra low porosity, low and extra low permeability reservoir, but the petrophysical property of the reservoir in Jurassic is relatively superior and the next is the reservoir of Triassic. There are three good source-reservoir-seal assemblages and the conditions of hydrocarbon accumulation are better in Miquan Block. The outcomes compared with other rich hydrocarbon regions indicate that Miquan Block is a favorable hydrocarbon exploration area.
