【摘要】 天然气水合物是由天然气和水在适宜条件下生成的一种类似于冰雪的白色晶体,是天然气资源的一种。它作为潜在的巨大能源和全球气候变化潜在的危机引起了人们的关注。天然气水合物对世界能源需求的贡献取决于开采技术和开采费用的大小,如果开采不当将会造成温室效应气体甲烷的排放和地层的坍塌,本文简要介绍了几种可能的开采方法和开采时应该注意的问题。最后,提出天然气水合物的资源开发利用应与环境保护协调发展。更多还原

【Abstract】 Natural gas hydrates are crystalline solids that form mixtures of water and light natural gases They are of considerable interest for their potential as an energy resource and for their potential role in global climate change From an energy resource point of view, the enormous amounts of methane hydrate under the ocean and beneath arctic permafrost represent an estimated 53% of all fossil fuel (coal, oil, natural gas) reserves on earth Contribution of natural gas hydrates to energy source depends on exploitation techniques and costs If exploitation techniques abused, would induce green-house gas CH4 released and ocean floor sunk Four techniques were introduced in brief and problems when exploiting we should pay attention to were raised At last, we concluded that the resource exploitation and ultil1zation of natural gas hydrate and environment protection should concordant develop更多还原
