摘　　要：罗斯海位于南极洲太平洋侧,通过对罗斯海气源沉积条件、地质构造条件和温、压条件对罗斯海天然气水合物成藏条件进行综合分析,结果表明罗斯海具备良好的天然气水合物储藏条件和勘探前景。本文在温、压条件的基础上,利用热流数据定量计算了天然气水合物稳定带的厚度,并使用体积分方法初步估算了该区域的天然气水合物的资源前景量。计算结果表明,罗斯海区域的天然气资源量为3.6×1011 m3,具有可观的经济价值。The Ross Sea is located on the Pacific side of the Antarctica.Based on the analysis of sedimentary,structural and temperature-pressure conditions,it is proved that the Rose Sea has good conditions for the reservation and exploration prospects of gas hydrates.The heat flow data were used to calculate the thickness of the gas hydrate stability zone in this study.An integral method was conducted to estimate the amount of gas hydrate resources in this region.The results show that the amount of gas resources of the Ross Sea region is 3.6×1011 m3,which means considerable economic value.
