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.

摘要： 东北亚地区天然气资源丰富,具有远景资源量约70×10¹²m³.这里盆地类型众多,是世界上以古克拉通继承性盆地和晚期岛孤相关盆地为主的新含气区域.中国的华北、塔里木、扬子地区和俄国的西伯利亚属于古老克拉通;上扬斯克坳陷和库车坳陷则属于前陆盆地或克拉通边缘坳陷;东北萨哈林和东海为弧后盆地.天然气资源主要分布在克拉通及其边缘坳陷或前陆盆地中,约占资源潜力的0%.其次为与中新生代岛弧有关的位于现今大陆架的第三系盆地,资源潜力约占10%以上.目前东北亚天然气开发还处在比较低的水平,但它将是世界新的重要天然气资源地,该地区本身的天然气需求量也有强劲增长趋势.
