Abstract：According to surface consistent model and its realization condition,the paper use conjugate-gradient algorithm to do spectral decomposition processing in time-domain and analyze it by resolved surface-consistent components,which considered that it is more reasonable to use shot,receiver and offset components for computation of deconvolution factor to eliminate influence of surface condition on seismic records.After data processing by selecting seismic records in the areas where typical complicated surface condition is,the results show that adopting the method proposed by the paper can effectively correct influence of complicated surface condition nn seismic reflection amplitude.The method has advantages of fast processing speed,strong anti-noise ability and ercellent applied results in seismic data processing in the areas of more complicated surface condition and poor signal-to-noise ratio.
