Abstract

Abstract

The comprehensive isotropic velocity field will affect the dynamic correction effect of the wide azimuth seismic gathers, and then affect the residual static correction effect, the azimuth anisotropy correction effect and the stacking effect. In the processing of wide azimuth seismic data, the NMO (Normal Move Out) velocity changes with the change of azimuth. The multi-directional velocity field obtained by the multidirectional velocity analysis can effectively improve the quality of gathers after NMO correction, eliminate the adverse effects of isotropic velocity field on the residual static correction and azimuthal anisotropy correction in OVT (Offset Vector Title) domain seismic data processing, and improve the flatness of gathers after NMO correction and the imaging accuracy of low order faults. The method proves to be effective in seismic data processing of CY-DZ exploration area in Nanyang sag.
