Abstract: There are abundant natural gas resources in the Northeast Asia area.Its prospective gas resource is about 70 trillion cubic meters. This area is a new gas source region where different types of basins dominated with paleo-cratonic inherited basins and late island associated basins were developed. The North China,Tarim and Yangzi areas in China and Siberia in Russia belong to paleo-cratons,and Verhne-yanskoe and Kuqa depressions belong to the foreland basins or cratonic marginal depressions,and the Northeast Sakhalin and the East China Sea are the back-arc basins.The natural gas is distributed primarily in the craton-inherited basins and cratonic marginal depressions or foreland basins,accounting for 80% of the total prospective gas resource.The Tertiary basins associated with the Middle Cenozoic island arc located in the present continent shelf have the resource potential accounting for over 10% of the total.Although gas development in Northeast Asia is still in a low level, this area will become a new important gas resource base in the world. The gas demand in Northeast Asia also shows a strong tendency of increase.
