| Abstract:As an efficient and clean energy resource, natural gas hydrate is widely distributed in ocean and permafrost. After exploration and development in recent years, abundant natural gas hydrate resources have been discovered in the South China Sea, and trial production has been carried out successfully. With the further acceleration of gas hydrate exploration and development, more and more researchers have paid attention to fidelity of the core sampler as an important tool for gas hydrate sampling. From the perspective of science popularization, this paper introduces the necessity of fidelity sampling of natural gas hydrate, the development process of foreign countries and the research achievements of China in recent years, so as to achieve the purpose of mutual exchange and mutual promotion, and finally promote the localized application of fidelity sampling technology. |
