| 摘 要： | 从冲绳海槽的地质条件来看，该区有利于天然气水合物的稳定存在，从沉积厚度和沉积速率来看，位于冲绳海槽盆地西侧的陆架前缘坳陷最有利于有机质的保存和转化，可以为冲绳海槽水合物的形成提供充足气源。通过对冲绳海槽区域地质条件和地球化学异常的综合分析以及地震特殊处理资料的精细解释，认为冲绳海槽南段很可能更适宜水合物的形成和聚集，因而可能会有很好的远景。 |

| Abstract: | The average water depth more than 1 000 m is advantageous to keep gas hydrate stable in the Okinawa Trough. According to sedimentary thickness and sedimention rate, Lujiaqianyuan depression lying to the west of the Okinawa Trough is the most favorable to preservation and transformation of organic matter, so the depression could provide enough gas for gas hydrate to form. Through integrated consideration of regional geological conditions and geochemical anomalies as well as special processing and interpreting of seismic data, we think that the south part of the Okinawa Trough is probably more suitable to form and accumulate gas hydrate, therefore, the south part probably has good perspective. |
