Abstract：On the basis of researches on the hydrate accumulation conditions of permafrost, source rock and temperature-pressure of the hydrate-discovered Muli Sag, geological analogue methods were applied to analyzing the development and occurrence potential of natural gas hydrate in the Hala Lake Sag. The results show that the Hala Lake Sag and Muli Sag have the same permafrost thickness and consistent temperature-pressure conditions, which indicates that the Hala Lake Sag basically possesses the environmental conditions for the gas hydrate formation. With regard to sedimentary evolution, material composition of the permafrost and hydrocarbon gas preservation, they display notable differences. Formations in the Muli Sag are well developed, the permafrost layer is primarily sedimentary rock, and distinct geochemical anomalies were detected. However, a depositional hiatus occurred between the Carboniferous and Jurassic in the Hala Lake Sag, the Triassic petroleum system was destroyed, and the Quaternary sediments are the main materials of permafrost, with poor capping capacity. Deeply buried Permian source rocks could provide hydrocarbon gases for gas hydrate formation. It is inferred that the local uplift of the Hala Lake Sag is a favorable region for the formation of gas hydrate.
