Description

technical field [0001] The invention relates to the technical fields of combustible ice mining and marine geological disaster simulation, in particular to an experimental device suitable for simulating seabed landslides caused by combustible ice mining. Background technique [0002] Combustible ice, also known as natural gas hydrate, is a new type of unconventional energy with great potential. Because of its large reserves, shallow burial, high energy density, wide distribution, and large scale, it is considered to be a strategic alternative energy source for oil and natural gas in the future. It is also of great significance to my country's energy security and economic development. The mining of combustible ice on the seabed is an important factor that induces some submarine landslides. The mechanism of action is that the pressure of the seabed deposition strata decreases or the temperature rises during the mining of combustible ice, which leads to the decomposition of combu...
