| Abstract: | As a new kind of high efficiency and clean energy resource, natural gas hydrate has extensively attracted attentions all around the world. The device used for sampling the natural gas hydrate core must possess the properties of warm preservation and pressure preservation due to its instability. The developing situations at home and abroad for sampling of the natural gas hydrate, a new preliminary concept for sampling of the natural gas hydrate were introduced. The coring tool research project included in the ＂Key coring technology for natural hydrate＂ was described, a major project of national ＂863＂ plan. |
