THE STATUS AND PROSPECTS OF RESEARCH AND EXPLOITATION OF NATURAL GAS HYDRATE IN THE WORLD

SHI Dou, ZHENG Junwei (The Scientific Information Center for Resources and Environment,CAS,Lanzhou,730000, China)  
Natural gas hydrates (occasionally called gas clathrates) are ice like crystalline substances containing hydrocarbon and non hydrocarbon gas. Gas hydrates were discovered firstly in laborary in 1810. Over a century later, in 1934 the observation of hydrates in pipelines caused them to be think with industrial problem. In 1965 the third era of hydrate research was entered as mankind determined the existence of reserves of hydrates in nature.This paper gave the current state and analysed the prospects of the research and development for natural gas hydrate in the world.Gas hydrate resource potential was evaluated for all over the world,too.At the last part,the policies were given which should be used in our country for natural gas hydyate research.
