Supergravity simulation system for depressurization production of natural gas hydrates

Abstract

The invention discloses a supergravity simulation system for depressurization production of natural gas hydrates. A hydraulic oil station is connected with a flow converging plate by an oil-way centrifuge rotating joint and is then divided into two paths; the two paths are connected with a high-pressure reactor through a supergravity water pressure control module and a supergravity mining controlmodule respectively; a kettle body temperature control module is connected with the high-pressure reactor through a water-bath passage centrifuge rotating joint; the high-pressure reactor, the flow converging plate, a data acquisition box, the supergravity water pressure control module and the supergravity mining control module are all arranged on a supergravity centrifuge located in a supergravity centrifuge air-conditioning chamber; the hydraulic oil station, a computer and the kettle body temperature control module are arranged out of the supergravity centrifuge air-conditioning chamber; and sensors in the high-pressure reactor, the supergravity mining control module, the supergravity water pressure control module and the kettle body temperature control module are all connected with thedata acquisition box. The supergravity simulation system of the invention can truly simulate catastrophic process in mining of natural gas hydrates and provide scientific support for simulation experiments of natural gas hydrate mining.

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 high-gravity simulation system for natural gas hydrate decompression mining. Background technique [0002] Natural gas hydrate refers to clathrate crystalline compounds formed by natural gas and water under high pressure and low temperature. Its appearance is like ice and snow, and it is flammable when exposed to fire. It is commonly known as "combustible ice". The combustion calorific value of natural gas hydrate per unit volume is 10 times that of coal and 2 to 5 times that of traditional natural gas. It is rich in reserves and is regarded by countries all over the world as one of the alternative energy sources for future oil and gas. [0003] Gas hydrates are generally distributed in the seabed or in permafrost on land, and the high pressure and low temperature conditions make them in a stable solid hydrate stat...
