Application of spectral decomposition method in channel identifying at W area
谱分解技术在W区河道识别中的应用

With the development of the exploration and exploitation in oil field,the prediction of thin reservoir and identification the special geology body plays a more and more important role in lithologic traps,so does the spectral decomposition.In this area,normal method can not identify the reservoir effectively,but in this paper,with the WVD time-frequency spectral decomposition method,we can sculpt the channel deposit body well.
