Description

technical field [0001] The application belongs to the technical field of hydrate exploitation, and in particular relates to a multifunctional experimental system for natural gas hydrate in-situ simulation. Background technique [0002] Natural gas hydrate is considered to be one of the most potential emerging green energy sources in the 21st century. It has the characteristics of abundant reserves and clean use. Natural gas hydrate is formed and stored stably in a high-pressure, low-temperature environment. Due to its special cage-like molecular structure, 1 volume of combustible ice can release 160 volumes of methane at an equal pressure state, and its energy density is quite considerable. With more and more attention paid to natural gas hydrates, how to more effectively explore and exploit seabed natural gas hydrates has become a new topic. Nowadays, all countries are facing certain difficulties in the exploitation of natural gas hydrates, including secondary generation o...

Problems solved by technology

[0003] Due to the special nature of hydrate occurrence, it is extremely difficult to coring the sediments of the seabed hydrate reservoir under pressure, and the sample transfer process in the in-situ state needs to maintain high pressure and low temperature throughout the whole process until it reaches the laboratory equipment, and the cost is too high And it is difficult to have supporting facilities
