摘　　要：天然气水合物是一种由天然气分子与水分子组成的类冰固态化合物 ,其稳定带与下伏游离气体带之间有明显的物性差异 ,这给地球物理勘探提供了前提条件。文中分析了天然气水合物在国内外的研究现状 ,针对目前方法应用中存在的问题 ,探讨了提高天然气水合物地球物理勘探效果的举措 ,指出海底多波多分量AVO技术是一种较有意义的手段 ,总结出今后的发展趋势。Natural gas hydrate is a kind of chemical compound of solid state like ice, composed of natural gas molecules and water molecules, and its steady zone and underlying dissociative gas zone differ in physical property obviously, which provides the basis for the geophysical exploration. This paper analyses the present research situation of gas hydrates at home and abroad, discuses the measures to improve the effect of geophysical exploration of gas hydrates as to the existing problems, points out that the AVO technology is a kind of effective approach, and draws the outline of the development trend in the future.
