| 摘 要： | 天然气水合物在一定温度压力条件下能以固体形式存在,但由于其特殊的热物理力学性质,难以像开采其它固体矿产资源的＂矿山＂型式来开发。在现有技术条件下,钻探技术是解决开采天然气水合物的技术、经济可行和避免可能由开采带来的环境问题的关键。鉴于通过钻探手段将天然气水合物在地下转化为可控的资源而后开采的现实,提出了采用化学浆液注入和降压相结合的开采模式。

| Abstract: | Gas hydrate can exist in certain temperature and pressure conditions as solid form,but because of its special thermal physical and mechanical properties,it is impossible to be developed with ＂mining＂ type like other solid mineral resources.Under the present condition,drilling technology is the key for the exploitation of gas hydrate;it is economically feasible and can avoid the environmental problems that might be brought by mining.Based on the situation that gas hydrate was converted to the controlled resource underground before mining,mining mode combining chemical grout injection with depression was proposed. |
