Description

technical field [0001] The invention belongs to the technical field of new energy, and relates to a multifunctional simulation experiment system of hydrate under the action of microorganisms. Background technique [0002] Natural gas hydrate is a solid crystalline compound formed by water and gas. Geological bodies in high-pressure and low-temperature environments such as deep sea and permafrost are suitable places for the formation and occurrence of hydrates. The reserves of natural gas hydrates exceed those of all conventional fossil fuels. In sum, it is considered to be the most important new type of clean and follow-up energy discovered in recent decades. The United States, Japan, India, and China have all carried out research on the formation and migration mechanism, occurrence characteristics, and mining methods of gas hydrates. [0003] The formation and decomposition of natural gas hydrate is a very complicated process, involving multiphase fluid flow, phase transit...
