The invention discloses a device and a method for measuring the gas-water two-phase relative content of combustible ice, wherein the device comprises a sample holder and a circulating temperature controller; the sample holder comprises a shell; a cooling liquid flowing cavity is formed in the shell. A closed sample cavity is formed in the cooling liquid flowing cavity, the surface of the sample cavity is sleeved with a hollow pipe, the hollow pipe is wound with a radio frequency coil, and cooling liquid enters the cooling liquid flowing cavity from the liquid inflow end of the cooling liquid flowing cavity and is discharged out of the cooling liquid flowing cavity from the liquid outflow end of the cooling liquid flowing cavity after passing through the hollow pipe; the circulating temperature controller comprises a temperature regulator and a circulating pump, the circulating pump is arranged on a pipeline between the temperature regulator and the sample holder, and the cooling liquidis injected into the pipeline. According to the embodiment of the invention, the circulating temperature controller is used for controlling the temperature of the combustible ice sample in the samplecavity, so that the accuracy of a measurement result is effectively improved on the basis of ensuring the integrity of the combustible ice sample.
Description
technical field [0001] The invention relates to the technical field of combustible ice mining, in particular to a device and method for measuring the relative content of gas and water phases of combustible ice. Background technique [0002] Combustible ice, as one of the important strategic energy sources in the world today, has attracted increasing attention. Generally, reservoirs rich in combustible ice occur in oceanic or polar regions. The importance of energy as a core resource and economic lifeline for competition among countries around the world is self-evident. How to promote the process of solving the technical problems of combustible ice mining is the current energy lifeline challenge for our country and even the world.
