【摘要】 综述了三十多年来各国学者对全球天然气水合物资源量的研究进展,总体上可分为三个阶段:(1)20世纪70年代—80年代早期(1017～1018m3量级);(2)80年代晚期—90年代早期(1016m3量级)和(3)90年代晚期至今(1014～1015m3量级)。分析发现,最早的估算结果比现今的偏大2～3个数量级。随着人们对水合物认识的加深,在资源量评估方面会显得更加理性。更多还原

【Abstract】 Natural gas hydrate is considered to be the most important energy resource to replace petroleum in the 21 century. The potential total resources volume of gas hydrate in the past 30 years is integrated and evaluated, which could be divided into three periods: (1) 1970s-early 1980s (1017～1018m3); (2) late 1980s-early 1990s (1016m3); (3) late 1990s-present (1014～1015m3). The first measured potential volume of gas hydrate was about 102～103 higher than today’s. It is recognized that the measured potential volume of the gas hydrate may not so huge as we thought before but it still can’t be neglected.更多还原
