  • In order to further improve gas hydrate drilling and sampling technology in the South China Sea, the requirements of the South China Sea sampling environment and gas hydrate characteristics of gas hydrate drilling and sampling technology were analyzed based on pre-development and field testing, which provided a detailed introduction to the sampling technology. Through an analysis of the difficulties encountered in developing sampling tools in key aspects such as tool size, low temperature insulation, sealing valve, sampling operation mode, etc., the countermeasures were studied according to the actual needs, by which a rope pressure-temperature-preserving sampling tool that suitable for gas hydrate sampling in the South China Sea was developed, along with recommendations having to do with the future research direction of gas hydrate drilling sampling technology. The result is a technical reference and a best practices guide for the further development and improvement of gas hydrate sampling technology in the South China Sea.
