利用地震瑞利波速度反演求取P-SV波横波静校正量

 在多波多分量地震勘探中，P-SV波横波静校正量的求取至今仍然十分困难。本文借鉴Muyzert的方法原理，提出利用陆上P-SV波地震资料中的瑞利波频散信息反演浅层横波速度结构，进而求取P-SV波的横波静校正量。但是在实施反演之前要对P-SV波资料先做高程静校正和纵波静校正。文中详细列出求取横波静校正量的流程。通过实际二维P-SV波地震资料试验表明，利用地震瑞利波的频散信息可有效地反演浅层横波速度结构，并可预测P-SV波横波静校正量的长波长趋势。

Using velocity inversion of seismic Rayleigh wave to compute S-wave statics of P-SV wave

In multi-wave and multi-component seismic exploration, it has been very difficult to compute S-wave statics of P-SV wave up-to-now. Aid by the principle of Muyzert approach, the paper presented using dispersion information of Rayleigh wave in land seismic P-SV wave data to invert shallow S-wave velocity structure, and then compute S-wave statics of P-SV wave. The paper listed in detail the flow chart computing S-wave statics. It is shown by the test of practical 2-D seismic P-SV wave data that using the dispersion information of seismic Rayleigh wave can effectively invert the S-wave shallow velocity structure and predict the long wavelength trend of S-wave statics of P-SV wave.
