天然气水合物作为一种新型能源,已经逐渐引起人们的重视。赋存于海底沉积物中的天然气水合物虽然本身作为亚稳定胶结物对海底有建造作用,但是由于其对特定温度和压力条件的严格依赖,海底温压条件的改变会引起其分解,从而使海底沉积物失稳甚至导致海底滑坡。本研究系统介绍了近年来国内外针对天然气水合物合成、物理性质及对海底稳定性影响进行的相关研究,并对今后研究进行了展望。

Natural gas hydrate is a new kind of energy attracting more and more attention.Although natural gas hydrate existing in the bottom deposits is a kind of metastable cement,being helpful in the sea floor formation,the helpful action depends on the special and strict conditions of pressure and temperature.Once the equilibrium condition is broken,the natural gas hydrate will be dissociated,which can cause sedimental instability leading to submarine landslide.The paper is giving a brief overview on the recent progress in natural gas hydrate studies of its synthesis,physical properties and the effects of natural gas hydrate dissociation on the slope stability,and the prospect in the future is also discussed.
