Compared with the earlier wavelet transform and Fourier transform,generalized S transform is better in time-frequency locality,but is easier to lose low frequency information and to miss weaker reflections.Therefore,the method of sesmic high-resolution processing based on generalized S transform was improved and a new idea of processing was developed.Using this improved method based on generalized S transform,high frequency signals can be extracted and compensateed,and simultaneously low frequency signals are effectively maintained.This improved method was applied in LH11-1 oilfield,resulting in good effects.
