Title:
SUPERGRAVITY HYDRATE RESEARCH TEST SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2021/227384
Kind Code:
A1
Abstract:
A supergravity hydrate research test system and method, which can emulate a seafloor hydrate reservoir and geological environments above and below said reservoir, change the temperature-pressure environment of a natural gas hydrate reservoir by means of methods such as extraction well depressurization and heat injection, i.e. a hydrate phase equilibrium criterion, and after in situ decomposition of solid hydrates in the reservoir layer into natural gas and water, subsequently extract the natural gas by means of an extraction well, thereby researching the influence of a relevant factor on hydrate decomposition.
