It is ice-like, non-chemical cage-shaped crystal compound, composed of the gas and small water molecules on certain conditions （appropriate temperature, pressure, gas saturation, water salinity, pH, etc.）. It can be represented with M-r^H20, in which M stands for gas molecules of hydrate, and n is the number of water molecules. Small-molecule gases CH4, C2H6, C3H8, C4Hlo equivalent homologue, as well as CO2, N2, H2S, etc., can form a single hydrate or multi-component of gas hydrate. Perhaps the most important gas hydrate is natural gas hydrate, which contains more than 99% methane molecules. So the natural gas hydrate is usually called methane hydrate.展开更多
