Title:
APPLICATION OF MICRO-INTERFACE STRENGTHENING SYSTEM IN MINING OF COMBUSTIBLE ICE
Document Type and Number:
WIPO Patent Application WO/2020/258701
Kind Code:
A1
Abstract:
Provided is an application of a micro-interface strengthening system in the mining of combustible ice. A method of applying the micro-interface strengthening system to the mining of combustible ice comprises: natural gas is introduced into a first inlet of the micro-interface strengthening system, brine heated by a heat exchanger is introduced into a second inlet, and the natural gas and the heated brine are mixed through the micro-interface strengthening system to obtain micro-bubble and/or micro-droplet emulsion; the obtained micro-bubble and/or micro-droplet emulsion is pumped into a first vertical shaft through a pump, wherein the upper end of the first vertical shaft is connected with the micro-interface strengthening system, and the lower end of the first vertical shaft extends into a combustible ice ore layer, the micro-bubble and/or micro-droplet emulsion melts the combustible ice ore layer into a gas-liquid mixture, the gas-liquid mixture is conveyed to a gas-liquid separation device through a second vertical shaft, and the natural gas is obtained from the separation of the gas-liquid separation device. The formed micro-bubble and/or micro-droplet emulsion is used to reduce the freezing point of the fluid in the molten combustible ice ore layer to make the fluid difficult to condense, thereby improving mining efficiency.
