Abstract:
P-SV wave statics is the “bottle neck” in land multi-wave exploration. Till now, there is not an effective method to solve this problem. Aiming at the actual situation in Daqing area, we proposed the combined statics method for P-SV wave. The model method based on three-component uphole data was used in combination with the modified common receiving point (CRP) stacking gather coherent method. Of the two methods, the model method can effectively solve statics problem for P-SV wave with long wavelength and the modified CRP stacking gather coherent method can solve the statics problem for P-SV wave with middle and short wavelength. The combination of the two methods can almost solve the statics problem for P-SV wave, remove the pseudo-structure caused by statics, increase the continuity of event, and obtain good seismic profiles of P-SV wave. So, the method can be widely popularized at flat area.
