天然气水合物资源潜力评价

作为一种新型能源的天然气水合物越来越引起人们的重视。研究表明，在永冻区水合物主要存在于地下130～2000m，海洋中的水合物主要存在于海底以下100～1100m，水合物矿层的厚度可从几厘米到30m左右。目前海相和极地永冻区水合物资源量估计约为20000万亿m^3。近些年来，很多国家包括日本、印度和美国投入大量的资金进行水合物资源的研究。虽然在有些基础性问题的研究上，如对已证实的含水合物地层中水合物聚集的资源量的估算等方面存在差异，但这些研究项目的开展可以帮助我们了解水合物储层的属性、开采体系的设计以及更为重要的开采成本及经济效益等关键性问题。

Assessment of Gas Hydrate Resource Potential

As a new energy type,gas hydrate is attracting more and more attention.Studies show that hydrate in the permafrost regions mainly exists at the depths of 130~2 000 m beneath the surface and marine hydrate is mainly present at the depths of 100~1 100 m beneath the seafloor,and the thickness of the hydrate zone can be several centimeter to about 30 m.Resources of hydrate in the permafrost and sea areas are estimated to be about 20 000 000 billion m~3.China should put more forces into the surveys of hydrate as Japan,India and US do and make hydrate serve the development of national economy.
