【Abstract】 On the basis of the analysis of the hypothesis in surface-consistent model,the conjugate gradient method is applied to decompose the seismic record in time domain in terms of the surface-consistent precondition and model. Application to real and typical seismic data for complex surface conditions shows that the effect of near-surface condition on seismic records can be effectively eliminated by means of the method presented here. For complex surface condition and low signal-to-noise area,this method has advantages such as faster,robust to noise.更多还原
