Description

technical field [0001] The invention relates to an experiment device, in particular to a simulation experiment device for the thermophysical characteristics of natural gas hydrate. Background technique [0002] The thermophysical properties of hydrates are important basic data in the exploration, development, storage and transportation of hydrates. Due to the high requirements for sample preservation, complex components and certain anisotropy, the research progress has been very slow. Obtaining the thermophysical property parameters of natural gas hydrate is mainly through two ways of field measurement and test laboratory synthesis of hydrate. The field measurement is to measure the hydrate samples or hydrate-containing sediments obtained in the ocean on board or in the laboratory. Because the field measurement is expensive and time-consuming, and the components of the hydrate samples extracted in the field are complex, it is not easy to measure. Therefore, very little work...
