Abstract: Accurate measurement of the hydrate thermal conductivity is a key to the development and application of hydrates storage air-conditioning technology. Limited to hydrate thermal properties and metastability characteristics, hydrates feature larger difficulties and errors in thermal conductivity measurement than conventional materials, therefore, traditional methods cannot be directly used in testing the hydrate thermal conductivity. In this paper, the basic principles, application and limitations of several test methods like the transient hot-wire method, the transient plane source, the steady-state plate method and the heat pulse probe technology are presented. Especially, the heat pulse probe-time domain reflectometry test method is introduced, which combines the heat pulse probe and transient plate heat source, and can be effective supplement to single measurement method available now. This method can provide more accurate results, and will be significant for the future development of hydrate storage technology and thermal conductivity measurement.
