天然气水合物是近年来在全世界范围内发现的一种可替代性的新能源,它是以甲烷为主的可燃气体,在低温高压环境下和水形成一种外貌很像冰块的固体燃料,点火就可以燃烧,所以又叫“可燃冰”。难怪发现它以后,立刻就引起了全世界各国的高度重视。迄今为止,沿各大洲的大陆边缘(陆缘)地带的海里都有发现,此外,在北美洲沿北极海一带的长年永冻层里也大量发现。经过科学家的测试,一立方米的“可燃冰”能释放出164立方米的甲烷气体。而且矿层分布极为广泛,目 Gas hydrate is an alternative new energy discovered worldwide in recent years. It is a methane-based combustible gas that forms a solid fuel that looks much like ice in low temperature and high pressure environment , Ignition can burn, so called “combustible ice ”. No wonder when it was discovered, it immediately aroused the great attention of all countries in the world. So far, discoveries have taken place along the continents of continental margins (continental margins) and in North America along many permanent permafrost regions in the Arctic Sea. After a scientist’s test, one cubic meter of “combustible ice” can release 164 cubic meters of methane gas. And extremely wide distribution of ore, head
