关于加强青藏高原多年冻土区天然气水合物开发研究的建议

Strengthening Development and Research of Natural Gas Hydrates in Qinghai-Tibet Plateau Permafrost

天然气水合物具有污染小、储量大、分布广、能量密度高等独特的资源优势,被誉为未来的战略接替能源,引起了世界各国的高度重视。虽然我国已分别在南海和青藏高原多年冻土区钻获了天然气水合物实物样品,但与天然气水合物开发研究强国相比技术差距仍然很大。鉴于陆域天然气水合物比海域天然气水合物勘查成本低、开采安全系数高、开采对生态环境影响小,建议当前我国应选择青藏高原多年冻土区重点部署天然气水合物的开发,并采取制定国家规划、加大投入力度、建立研发基地等措施加强其开发研究。

Due to its little pollution,large reserves,wide distribution,high energy density,natural gas hydrate（NGH） has been known as a future strategic energy to succeed and attracted the world＇s high attention.Although NGH samples has been achieved in the South China Sea and Qinghai-Tibet Plateau permafrost,the technology gap of China remains large compared to the NGH dominant countries.In view of the lower cost,higher safety factor and smaller impact on the environment of exploiting NGH in land than in sea,this paper proposes China to firstly choose the Qinghai-Tibet Plateau permafrost to deploy the development of NGH,and to take some measures to strengthen its development research,such as making national plan,increasing investment,establishing RD base.
