摘　　要：天然气水合物广泛地分布于具有一定水深的海底与中高纬度陆地永久冻土带,蕴藏着巨大的资源潜力,使水合物的资源价值成为长期持续的研究热点。不仅如此,天然气水合物的形成还对纯水具有富集作用,而且不同气体形成水合物的温压条件也有差异,促进了天然气水合物利用技术研究的兴起。另一方面,天然气水合物的稳定性直接受温压等外部因素控制,相对易于形成与分解,从而使水合物防治、水合物对环境潜在影响成为水合物研究领域的重要研究内容。因此,天然气水合物研究涵盖了资源、防治、利用、环境4大主要方向。作者总结了天然气水合物的基本性质以及现阶段水合物研究领域的主要研究方向,分析了各研究方向的主要研究进展与研究趋势,对于今后天然气水合物研究具有一定启示意义。Gas hydrate is distributed widely in the ocean areas with certain depth of water and the permafrost zones in the middle and high latitudes,and has huge resource potential.The ability to enriching natural gas and pure water in gas hydrate formation,as well as the differences in the temperature and pressure conditions required for different gases to generate hydrate,promote the research of natural gas hydrate utilization technology.Meanwhile,the stability of gas hydrate is controlled directly by the external factors such as temperature and pressure,and is easy to form and decompose,so that the potential impact of hydrate on environment becomes a continuous issue in gas hydrate research field.Natural gas hydrate research covers mainly 4 directions at present,including resource potential,hydrate prevention,hydrate utilization and the potential impact on environment,showing vigorous research trends in various directions.Based on the present research situation,the authors summarize the basic characteristics and the main research directions of gas hydrate,and analyze the recent advances and the further trends of various gas hydrate research directions,which will provide certain implications for the further research of natural gas hydrate.
