Study on P and S wave separation method in cross-well seismic and its application
Online published: 2013-09-26
Three-component seismic acquisition technology used in VSP and cross-well seismic can record wealthy seismic wave field. The P and S wave couple together, which becomes the difficulty and emphasis of data processing. Through analyzing borehole seismic acquisition system, combined with polarity relation of P and S wave in different components, we can associate polarity of P and S wave with apparent velocity and direction of seismic wave reaching the geophone array. According to this relation, we obtained the distribution relation of P and S wave in τ- p domain based on the linear Radon transform （LRT）. Considering the convergence of LRT, we designed a polarization filteringmethod using the high-resolution Radon transform, and then accomplished the separation of P and S wave. The processing of
simulated data of theoretical model and practical cross-well model separated P and S wave field successfully, which is useful for independent imaging of P and Swave.
