Description

technical field [0001] The invention relates to the field of marine natural gas hydrate exploitation, in particular to a marine natural gas hydrate exploitation simulation device. Background technique [0002] Natural gas hydrate is also called combustible ice because of its appearance of ice-like crystals. Natural gas hydrate has huge reserves in the world, and its combustion emissions are cleaner than those of oil and coal. The conditions formed under the conditions are relatively harsh. The environment requires high pressure, low temperature and water. At the same time, it also needs bacteria such as aerobic and anaerobic bacteria to decompose organic matter to form natural gas hydrates. Therefore, natural gas hydrates mostly exist in the soft muddy seabed. In the shallow layer, the distribution of natural gas hydrate deposits on the seabed is characterized by a wide area but a thin thickness. Therefore, the traditional shaft mining method has low mining efficiency, while...
