摘　　要：南极南设得兰陆缘天然气水合物分布广泛,因其在资源、地质灾害及全球气候变化等方面具有重要作用,成为国内外研究的热点。为此,从天然气水合物储层的地震识别特征、水合物相关地质构造、水合物储层定量评价以及水合物与气候变化关系等方面对南设得兰陆缘水合物储层的地球物理研究工作进行了梳理和总结,获得了几点思考与认识,以期为今后天然气水合物勘探开发及气候变化研究提供一定的参考借鉴。最后对该区域水合物储层地球物理研究方向进行了展望,认为综合利用海底地震仪数据的纵横波信息开展水合物储层三维表征研究、深入研究天然气水合物对全球变暖的响应机制及其反馈作用等是未来重要的发展方向。Gas hydrates,widely distributed along the South Shetland margin(offshore Antarctic Peninsula),have become a hot research topic nationwide and worldwide due to their significant role in addressing resources,geohazards,and global climate change issues.This paper reviews and summarizes the geophysical research on gas hydrate reservoirs in the South Shetland margin from the aspects of seismic identification characteristics of gas hydrate reservoirs,geological structures related to gas hydrates,quantitative evaluation of gas hydrate re-servoirs,and the relationship between gas hydrates and climate change.Some ideas and understandings are ob-tained to provide useful references for future exploration and development of gas hydrates and research on cli-mate change.Finally,prospects for geophysical research on regional gas hydrate reservoirs are presented.It is proposed that comprehensively utilizing the longitudinal and transverse wave information of underwater OBS data for 3D characterization of gas hydrate reservoirs and further researching the response mechanism and feedback effects of gas hydrates on global warming are important development directions in the future.
