摘　　要：分析了鄂尔多斯盆地下古生界气藏的地质特征,指出下古生界大型工业气藏形成的关键在于三个"有利搭配",即封闭海域与宽阔坪台搭配造就了有利生储相带;剥蚀脊与沟槽搭配孕育了良好的储集空间和有效的地层-岩性遮挡;孔隙空间与裂隙网络搭配做到了储产兼备。在此基础上指出鄂尔多斯盆地下古气藏仍具有向东和向南滚动勘探开发的远景。Analyzed geologic character of the Lower Paleozoic carbonate reservoir in Ortos basin. Indicate wrought key of the reservoir consists in three advantaged groups , opposite close of a ocean and wide flat mesa together builded advantaged sedimentary facies of oil source and reservoir, denudation ridges and erosion flutes together to gestated advantaged interspace and shelter from stratum-lithology, a pore and a fracture together creates a reserves and a yield. Base on these indicated that, reservoir has foreground of exploration and exploitation to east and south.
