In this paper,the seismic data of line(USGS95-1) in Blake Ridge are studied through wavelet multi-scale method to show that wavelet scales of seismic data from hydrate sediments are larger than the ones of the data from free gas layer.

• 以布莱克海台USGS95-1测线地震数据为例利用小波变换进行多尺度研究发现水合物层和游离气层表现出不同的尺度特征:水合物层表现出大尺度特征,而游离气层具有小尺度特征;
