| Abstract:Natural gas hydrate is a potential alternative energy source that is stable under the conditions of certain low temperatures and high pressures. In the gas hydrate drilling, cooling and temperature insulating technology is one of the key technologies. Low temperature can inhibit the decomposition natural gas hydrate, which is very important for hydrate samples obtaining. This paper summarizes the research status of submarine natural gas hydrate sampler in cooling and temperature insulating technology at the first, the thorough investigation and analysis are made. Then the cooling and temperature insulating technology of Japan PTCS sampler and the sampler technology in China are described in detail, the related technologies are analyzed and summarized. Finally, the development of the cooling and temperature insulating technology for the natural gas hydrate sampler is summarized and predicted. |
