Abstract

The invention discloses a natural gas hydrate heat shock method mining simulation device under a supergravity condition. A hydraulic oil station is connected to a confluence plate through an oil pathcentrifuge rotation joint to be divided into two paths, wherein two paths are respectively connected to a high-pressure reactor through a supergravity hydraulic pressure control module and a supergravity heat shock module; a supergravity gas-liquid separation module is directly connected to the high-pressure reactor; a kettle body temperature control module is connected to the high-pressure reactor through a water bath passage centrifuge rotation joint; sensors in the high-pressure reactor, the supergravity hydraulic pressure control module, the supergravity heat shock module, the supergravitygas-liquid separation module and the kettle body temperature control module are all connected with a data collection box. According to the natural gas hydrate heat shock method mining simulation device, the cataclysm process of on-site natural gas hydrate heat injection mining can be truly simulated, and a scientific support is provided for a natural gas hydrate heat injection mining simulation experiment.

Description

technical field [0001] The invention relates to a high-gravity physical simulation experiment system in the field of geotechnical engineering, in particular to a natural gas hydrate heat-shock mining simulation device under high-gravity conditions. Background technique [0002] Natural gas hydrate is an ice-like clathrate crystalline compound formed by water molecules and hydrocarbon molecules under high pressure and low temperature, commonly known as "combustible ice". Under standard conditions, a unit volume of natural gas hydrate can release as much as 160 to 180 volumes of methane gas, and the combustion heat value per unit volume of natural gas hydrate is 10 times that of coal and 2 to 5 times that of traditional natural gas. It is rich in reserves and has huge resource potential, and is regarded as one of the alternative energy sources of oil and gas in the future by countries all over the world. [0003] Gas hydrates are generally distributed in the seabed or in perm...
