LU Peng-fei1,YANG Chang-chun1,GUO Ai-hua2(1.Institute of Geology and Geophysics,Chinese Academy of Sciences,Beijing 10029,China;2.Department of geophysical exploration,Exploratory Development Institute,Jidong oil field,Tangshan 063004,China)  
Frequency-spectrum imaging technique based on frequency-spectrum decomposition is a special interpretation tool to reservoir characterizing,and is the key method in seismic attribute analysis.This technique has high resolution in space horizontal and is a tool in high resolution imaging and characterizing time depth of layers in reservoir with multi-scale information of 3-D seismic data.This technique has some advantages over some traditional methods of seismic attributes on defining the field of reservoir and computing layer depth,for example,the changes in time depth of layers are identified from the amplitude spectrum of seismic data and we can detect geological body with horizontal un-continue.Time-frequency analysis is the important method to this technique.The basic information about frequency-spectrum imaging and popular method in time-frequency analysis in present are firstly listed.Then,some new time-frequency analysis methods are simply introduced,such as generalized S transformation and modified matching pursuit.
