摘要

摘要: 南海北部陆坡区的台西南盆地是天然气水合物潜在分布区之一,水合物稳定带的研究对天然气水合物成矿与分布规律以及资源评价都具有重要意义,根据SO-177中德合作航次南海北部陆坡天然气水合物地质的调查资料,结合天然气水合物的相平衡条件和相应的压力-温度方程,计算了台西南盆地A区和B区的水合物稳定带厚度,并讨论了水合物稳定带厚度的分布特征。另外,对A区和B区天然气水合物中甲烷资源量进行了初步估算,估算结果为:A区甲烷资源含量为8.573 9×10¹¹~5.144 3×10¹² m³,B区甲烷资源含量为1.451 8×10¹²~8.711 1×10¹² m³,A区和B区甲烷资源总量约2.302 9×10¹²~13.854 4×10¹² m³。初步估算结果显示,台西南盆地天然气水合物甲烷资源量潜力巨大。

Abstract: The Taixi'nan Basin is one of the potential areas containing gas hydrate and located on the continental slope of South China Sea. The study of the hydrate stability zone (HSZ) is of great significance to the research of the deposition and distribution features of marine gas hydrate, and its resource assessment. Based on the gas hydrate data from SO-177 Sino-Germany cooperation cruise, we calculated the thickness of the gas hydrate stability zone in the areas of A and B in the Taixi'nan Basin. Furthermore, with the Geographic Information System (GIS) as a tool, we calculated the amount of methane contained in gas hydrate under normal condition.It is:8.573 9×10¹¹~5.144 3×10¹² m³ for area A, 1.451 8×10¹²~8.711 1×10¹² m³for area B, and 2.302 9×10¹²~13.854 4×10¹² m³ in total. The results show that there is great methane resource potential in the Taixi'nan basin.
