摘    要:界定了天然气水合物的概念与基本特征,分析了国内外最新研究动态和深海调查成果。认为迄今为止全球天然气水合物含甲烷资源的定量评估可以分为1980年以前的“推测性”阶段。1980年至1995年的“底限值”阶段,和1995年以来的“确定性”阶段。目前,中国天然气水合物调查研究面临的最大难题是深海原位天然气水合物实物样品的保真采集,而技术瓶颈系深海天然气水合物保压保温取心钻具的研制和调查者对配套高技术调查船舶的拥有及航次的科学调配。

关 键 词:天然气水合物  研究  资源  世界

Abstract:The concept and basic features of natural gas hydrate are limited and the newest domestic and foreign research trends and deep sea survey results are analyzed in the paper. It is pointed out that, up to now, the quantitative evaluation of methane contained by natural gas hydrate in the world may be divided into three stages, i.e. the “inference” stage before 1980; the “cutoff” stage from 1980 to 1995 and “definiteness” stage since 1995; at present, the greatest difficulty faced by the natural gas hydrate investigation in China is the fidelity acquisition of the abyssal original place gas hydrate samples; and the key techniques are the development of core drill which can make the initial pressure and initial temperature in the hydrate be well preserved, and the possession of investigating ship assembled with high technology and the scientific allocation of the number of voyages.
