Abstract: Gas hydrate is a kind of potential huge energy. It is important to develop gas hydrate exploration and get its distribution and reservoir volume, which plays a critical role to develop Chinese gas hydrate industry. The international gas hydrate investigation and research have a tendency of multi-subject and multi-technology, but the exploration of gas hydrate in China is still at the stage of beginning. The international geological, geophysical and geochemical gas hydrate exploration technology were reviewed,especially gas hydrate research situation in China.

Key words: gas hydrate, geophysical exploration, geochemical exploration

摘要： 天然气水合物是一种潜在的巨大能源,发展天然气水合物勘探技术，准确确定天然气水合物的分布与蕴藏量，对我国天然气水合物产业的建立有至关重要的作用。目前，国际上天然气水合物调查研究已呈现多学科、多方法的发展趋势，而国内天然气水合物勘探刚刚起步。总结了国内外地质、地球物理、地球化学等天然气水合物勘探技术，并介绍了我国天然气水合物的研究现状。
