摘　　要：天然气水合物是以甲烷为主的怪类气体与水分子组成的似冰状结晶化合物,主要分布在陆地永冻土带、大陆边缘的海洋底部以及深海海底平原。作为清洁、高效、大储量的新型能源,天然气水合物引起世界各国的高度重视,美国、日本、印度、韩国等国对天然气水合物调查研究和开发准备工作全力推进,近几年研究重点由资源调查逐渐转向开发利用。我国的天然气水合物研究也受到政府的高度重视和大力支持,现已成为热点研究课题。本文阐述各国天然气水合物最新研究进展,对促进我国天然气水合物的勘探开发具有重要意义。Natural gas hydrate is a clathrate compound formed by hydrocarbon gas(methane)and water,also known as flammable ice.It's mainly distributed in terrestrial permafrost,the bottom of ocean on continental margin and deep ocean plain.As a new,clean,efficient and abundant energy resource,countries around world give their attention to the natural gas hydrate.Such as the United States,Japan,Korea and India,they both actively promote preparatory work of gas hydrate investigation and development.In recent years,the research focuses on the development and utilization.Natural gas hydrate research in China has been highly valued and supported by the government,and has become a hot research topic now.The latest research progress of some countries is described in this paper,it's significance to research of gas hydrate exploration and development in our country.
