Description

technical field

[0001] The invention belongs to the technical field of energy exploitation, and in particular relates to a real-time monitoring device for seabed deformation during hydrate exploitation. Background technique

[0002] Gas hydrate is a crystalline substance formed by natural gas and water under low temperature and high pressure. It looks like ice and is flammable. It is commonly known as "combustible ice". It exists widely in permafrost and seabeds. It is estimated that the carbon content in natural gas hydrate is twice the total carbon content of other fossil energy sources, and it is a potential energy resource.

[0003] At present, three main mining methods have been proposed, including depressurization mining method, heat injection mining method, and chemical inhibitor injection mining method. Among them, the mining conditions of seabed natural gas hydrate are harsh and the mining is more difficult. Submarine gas hydrate reservoirs have a certain bearing ...
