气体水合物是一种笼状的包含甲烷气分子的晶状化合物 ,最常见的晶体结构是４６个水分子包围８个甲烷分子。在特殊的热力学条件下 ,陆上永冻层之下和近海地区特别是水深５００ｍ以下的沉积层都能形成大量气体水合物。大洋钻探在深海环境的海底浅部已发现水合物。随着石油勘探向
Gas hydrate is a cage-like crystalline compound containing methane gas molecules. The most common crystal structure is 46 water molecules surrounding 8 methane molecules. Under special thermodynamic conditions, a large amount of gas hydrate is formed beneath the permafrost and offshore sediments, especially below 500 m depth. Ocean Drilling Hydrates have been found in the shallow seabed of the deep-sea environment. With the exploration of oil
