Natural gas hydrate interpretation

Natural Gas Hydrate (abbreviated as Gas Hydrate), also known as clathrate, is under certain conditions (suitable temperature, pressure, gas saturation, water salinity, pH, etc.) An ice-like, non-stoichiometric, cage-shaped crystalline compound made up of water and natural gas that burns on fire. It can be expressed as M·nH 2 O. M represents a gas molecule in a hydrate, and n is a hydration index (that is, a number of water molecules). Components that make up natural gas such as CH 4 , C 2 H 6 , C 3 H 8 , C 4 H 10 equivalents, and CO 2 , N 2 , H 2 S, etc., can form single or multiple natural gas hydrates [1] . The main gas that forms natural gas hydrates is methane, and natural gas hydrates with a methane molecular content of more than 99% are often referred to as methane hydrates (Methane Hydrate).

Natural gas hydrates are widely distributed in nature on the slopes of the mainland, islands, uplifts of active and passive continental margins, polar continental shelves, and deep water environments of the oceans and some inland lakes. Under standard conditions, the decomposition of a unit volume of gas hydrate can produce up to 164 units of methane gas, which is an important potential future resource.
