The natural gas resource is abundant in Qaidam Basin，including Tertiary oil-type gas in the west，Jurassic coal-type gas in the northern margin and Quaternary biogenetic gas，Neogenthermogenic gas and Carboniferous coal-type gas in the east of the Qaidam Basin.In recent years，Jurassic coaly gas in the northern margin of Qaidam Basin has achieved a breakthrough and great exploration potential.
Based on the analysis of natural gas geological conditions，summarizes the palaeo-uplift in the rich hydrocarbon sag area，extrinsic uplift-slope and late tectonic gas accumulation model，and evaluates the conventional natural gas resources in the northern margin of the basin with analogies and genetic methods，a total resource of 11 457.5×108m3.On this basis，combined with the current situation of exploration，the remaining resources and their distribution were clarified，and the amount of remaining natural gas geological resources was 10 671.28×108m3 is mainly distributed in the Eboliang-Gourd mountain block and eastern zone in front of Alkin Mountains.According to the research results，it is pointed out that the Eboliang -Lenghu tectonic belt，the eastern section of Alkin piedmont，and the Middle-Lower Jurassic depression-slope area are the favorable target areas for natural gas exploration in the northern margin of Qaidam Basin.
