| 摘 要： | 中国是世界上第三大冻土国，在青藏高原和东北大兴安岭地区分布着大片的多年冻土区，并有较好的天然气水合物形成条件和找矿前景。20世纪90年代末就有部分科研人员开展了中国冻土区天然气水合物形成条件和分布预测的研究工作。2002年开始，中国地质调查局先后设立了5个地质调查项目，对中国冻土区开展了地质、地球物理、地球化学和遥感调查工作，并在祁连山冻土区成功地钻获了天然气水合物实物样品，取得了找矿工作的重大突破，使中国成为世界上既有陆地水合物也有海底水合物的少数几个国家之一。目前中国冻土区天然气水合物研究中仍存在着调查研究程度较低、技术装备落后、未开展试生产研究等问题。随着国家对天然气水合物重视程度的加强，中国冻土区天然气水合物的调查研究进程将会进一步加快，并有可能在不久的将来实现试生产。

| Abstract: | China is the third largest permafrost country in the world with 2.15×106 km2 permafrost zones, which are mainly located in the Tibetan Plateau of western China and the Da Hinggan Mountains in northeastern China, where there are fairly good formation conditions and prospects for gas hydrate. The formation conditions and potential of gas hydrate in China's permafrost have been studied since the end of the 1990s. Five projects have been implemented by China Geological Survey, in which geological, geophysical and geochemical investigation, drilling, and remote sensing survey have been performed since 2002. Gas hydrate was discovered in the Qilian Mountain permafrost in 2008, which makes China to be one of the few countries that possess both marine and permafrost gas hydrates. However, there are four problems to be solved, i.e., relatively low exploration level, backward key technique and equipment, low-level basic research and lack of trial production test. Progress of the exploration and research and production test of gas hydrate in permafrost zones will be surely accelerated in China because of the increasing attention and support from Chinese government. |
