The invention provides a device and method for measuring the decomposition rate of combustible ice. The device includes: a sample holder; a temperature regulation system connected to the sample holder through a temperature regulation pipeline; and the sample holder The driving pump connected through the temperature regulating pipeline; the sample holder is used to hold the combustible ice sample; the temperature regulating system can adjust the temperature of the fluid in the temperature regulating pipeline to a predetermined temperature; the driving pump is used to drive the pipeline fluid flow within. The method includes: acquiring the first transverse magnetization vector value; acquiring the second transverse magnetization vector and the time corresponding to the second transverse magnetization vector; recording the initial value when the second transverse magnetization vector does not change over time, and the The time corresponding to the initial value; determine the decomposition rate of the combustible ice sample according to the first transverse magnetization vector value, the initial value, and the time value. The invention can realize accurate measurement of the decomposition rate of combustible ice.
Description
technical field [0001] The present application relates to the technical field of combustible ice mining, in particular to a device and method for measuring the decomposition rate of combustible ice. Background technique [0002] Combustible ice is distributed in deep sea sediments or permafrost, and is a crystalline substance formed by natural gas and water under high pressure and low temperature conditions. Combustible ice is an important energy source used by countries all over the world. Therefore, the mining process of combustible ice is very important. [0003] In a mining method of combustible ice, the combustible ice is firstly taken out from the formation, and then the combustible ice is decomposed by phase change, and then the decomposition products of the combustible ice are collected and used as energy. The phase change decomposition of combustible ice means that the combustible ice is decomposed into alkane gas and water by solid phase change, and the alkane gas...
