摘　　要：天然气水合物是蕴藏于海洋大陆架及陆地永久冰土带的碳氢化合物,将来可能成为人类的重要能源之一。为此,阐述了天然气水合物的分布和形成机理,对比研究了天然气水合物的降压法、热采法、化学试剂法、水力压裂法等几种不同的开采方式,提出了尽快开展室外天然气水合物钻采方法研究以及我国南海和东海海区天然气水合物勘查研究工作的建议。Gas hydrate, a kind of hydrocarbon, can be found in both ocean continental shelf and terrestrial permafrost regions. It will possibly become one of the most important energy resources. In this paper, both distribution and formation mechanism of gas hydrate are illustrated; several different exploitation methods, such as depressurizing, thermal recovery, chemical reagent and hydraulic fracturing, are comparatively studied. A suggestion is also made that a field research on drilling and exploitation method for gas hydrate should be conducted as soon as possible and a survey of gas hydrate should be conducted in South China Sea and East China Sea.
