Problems solved by technology
Before the hydrate slurry enters the pipeline, it must be kept flowable and not decomposed. However, the conditions for the gas hydrate powder to be stable and not decompose are low temperature and high pressure. Under low temperature conditions, the brine mixed with it will freeze, making it unable to flow. It is impossible to add natural gas hydrate powder into the tank under high pressure
Therefore, mixing natural gas hydrate powder with brine to form a flowable slurry has become a difficult problem in the experiment. There is no one in the prior art that can ensure that the gas hydrate is mixed with brine to form a flowable slurry without decomposing.

Description
technical field [0001] The invention relates to a mixing tank for natural gas hydrate experiments and a method for storing natural gas hydrates, in particular to a mixing tank for natural gas hydrate experiments and a method for storing natural gas hydrates in the field of natural gas hydrate experiments. Background technique [0002] Natural gas hydrate is a non-stoichiometric cage-like crystalline substance produced by water and natural gas under high pressure and low temperature environment. It is an unconventional energy source with high density and high calorific value. It is generally believed that natural gas hydrate will be the most promising energy source in the 21st century The replacement energy of natural gas hydrate, especially marine gas hydrate, has not been developed due to its large amount and has not been widely valued. In the process of solid-state fluidized production, the flow decomposition test of natural gas hydrate in the pipeline has become an importa...
