天然气水合物的研究与开发现状

天然气水合物俗称可燃冰,又称笼形包合物,它是在一定条件下(合适的温度、压力、气体饱和度、水的盐度、pH值等)由水和天然气组成的类冰的、非化学计量的笼形结晶化合物.海底天然气水合物分布范围占海洋总面积的10%,是迄今为止海底最有价值、最具前景的能源,足够人类使用1000年.综合介绍了当前天然气水合物的研究与开发状况.从天然气水合物的存在环境、物理化学性质、钻探、开发、环境影响五个方面做了介绍.

Study and development on gas hydrate

Gas hydrate, usually called as combustible ice or cage inclusion complex, is non-stoichiometric cage crystal compound which is similar to ice. It is composed of water and gas and formed in the proper temperature, pressure, gas saturation, water salinity and pH. Submarine gas hydrates is the best valuable and promising energy source so far, which covers 10% sea area and is enough for human to use 1000 years. This paper reviewed the study and development on current gas hydrate and presented its existing surroundings, physiochemical properties, drilling and exploration, production and environmental impact.
