天然气水合物的资源与环境意义

天然气水合物是在低温高压环境下由水分子和气体分子构成的结晶状特殊固体化和物,它主要分布于永久冻土带及浅海大陆架及深海平原沉积物中。天然气水合物的开发利用涉及两个方面的问题:①从资源方面考虑,天然气储量巨大,能够满足人类未来清洁能源的需求;②从环境方面考虑,甲烷的释放将引发全球气候变化和一系列的海洋地质灾害。因此,在开发利用天然气水合物之前,必须有超前的防范措施,以防止天然气水合物对环境造成的不良影响。

The Resourceful and Environmental Significance of Natural Gas Hydrates

Natural Gas Hydrate occurs at conditions of low temperature and high pressure, it is a special solid crystal compound composed of natural gas molecule and water molecule.It mainly distributes in long ice crust and shallow continent and deep oceanic sediment. The exploitation and application of Natural Gas Hydrate involve tow issues: consided from resource aspect, it contains a very large amount of gas resource and will provide us with sufficient clean energy in future; consided from environment aspect, the release of CH4 from Natural Gas Hydrate can cause the global climate change and ocean disaster. Before the exploitation and application of Natural Gas Hydrate, we must have foresight measures, avoide it's negtive influnce to the environment.
