[0036] Gas hydrate is a kind of enveloping crystal formed by the interaction of gas or volatile liquid with water. Natural gas hydrate needs to exist under high pressure and low temperature, so its thermophysical properties need to be measured in situ.
[0037] See figure 1 As shown, a device for in-situ measurement of the thermophysical properties of a sample includes a reactor 8 containing a sample 813 to be tested, a gas supply system that provides a gas source for the reactor 8, and a temperature control system that maintains the reaction temperature in the reactor 8, And the hydraulic transmission system connected to the reactor 8, and the measurement and control acquisition system connected to the reactor 8 and used to test the thermophysical properties of the sample. The bottom of the barrel 82 of the reactor 8 is provided with a background material 814 with a thermal conductivity lower than the measured sample 813. The measurement and control acquisition system includes a ...
