英文摘要The separation of P- and S-wavefields from multi-component seismic data is very important, which has a direct impact on the follow-up data processing. In isotropic media, P-wavefield is curl-free and S-wavefield is divergence-free, so the P- and S-wavefields can be separated by taking the divergence and curl in frequency-wavenumber domain. However, only when the surface P velocity and S velocity are known, the P- and S-waves will be separated. In the paper, a method of estimating surface P velocity and S velocity is developed, which can obtain the surface velocities, even if they are unknown. A method for correcting phase and amplitude ratio of P-wave and S-wave is also presented, which solves the problem that the phase and amplitude ratios of P-wave and S-wave are changed after taking the divergence and curl.
