Abstract:As the velocity ratio is changing with time,the time matching from P-SV to PP time domain will distort seismic wavelet which includes waveform stretch and phase delay.To solve this problem,we propose an improved method for P-P and P-SV wave time matching.This method,based on Fourier's time stretch theory,can correct simultaneously wavelet amplitude and phase resulted from the different stretch value with the seismic travel time.The modeling data results of a well log data indicate that the method can correct simultaneously wavelet amplitude and phase.And the method is still stable when the data is noised.
