每种水合物都有特殊的温度-压力稳定场,一般存在某一标配压力(通常取水合物在0℃条件下存在的临界压力),可根据该压力估计存在特殊气体水合物所需的地质条件。在0℃条件下,纯甲烷水合物存在需要的临界压力约26MPa(相当于约260m的淡水柱,对于海水要减少约3.5％),而纯乙烷水合物存在需要的临界压力约5.2MPa(相当于约52m的淡水柱和约50m的海水柱)。温度高于
Each hydrate has a special temperature-pressure stability field, generally with a standard pressure (usually the critical pressure at which the hydrate is present at 0 ° C), from which pressure the amount of gas required for the presence of a particular gas hydrate Geological conditions. At 0 ° C, pure methane hydrate has a critical pressure of about 26 MPa (equivalent to a freshwater column of about 260 m and a reduction of about 3.5% for seawater), while pure ethane hydrate has a required critical pressure of about 5.2 MPa ( Equivalent to about 52m freshwater column and about 50m seawater column). Temperature is higher than
