摘　　要：21世纪以来,地震勘探技术、岩石物理学理论和水合物研究的迅速发展使得水合物地震识别方法研究逐步深入,取得了前所未有的新进展.本文回顾了海洋水合物地震识别方法的研究历程,总结了水合物地震识别技术现状,认为纵、横波资料联合应用的弹性参数反演、基于黏弹介质的地震波吸收特征研究是海洋水合物地震识别技术的近期发展方向;水合物对岩石微观结构改变的作用机理及其最佳岩石物理模型和地震响应或属性特征研究是海洋水合物地震识别技术的未来宏观发展方向.Since Entering into 21 century,researches of seismic exploration techniques,seismic rock physics and marine gas hydrate have been developed rapidly,which has promoted the deepenning and great advancing of seismic identification approaches of marine gas hydrate. This paper,aiming at seismic identification approaches of marine gas hydrate, reviewed their developing process,summarized current status of their techniques used,and anticipated their future development directions. We pointed out that elastic parameters inversions using pressed wave and sheared wave integratedly are the short-term directions for marine gas hydrate seismic identification approaches research, as well as the attenuation theories and characteristics of gas hydrate-bearing sediments. In addition,the mechanism for gas hydrate to affect rock＇s microcosmic structures,the optimal rock physical model that could describ the mechanism, and the seismic responses or attributes＇ characteristics of the rock physical model are the longterm directions for them.
