Luacustrine mudstone and sapropel coal in the middle Permian and the low Jurassic as well as cannel boghead in the middle and upper Triassic have abundant exinoid group and saprepel group, they have highest hydrocarbon-generating potentiality in the basin, while humic coal distributed in the middle and lower Jurassic has abundant vitrinite and inertrinite which has poor liquid hydrocarbon genera.

中二叠统和下侏罗统湖相泥岩和腐泥煤以及中上三叠统烛藻煤富含壳质组和腐泥组 ,生油潜能极高 ;下中侏罗统腐殖煤富含镜质组和惰质组 ,生液态烃能力较差。
