Abstract

Seismic imaging of the high-steep structural zone in southern Biyang Depression is difficult.In order to improve imaging accuracy,in this paper,the authors studied and applied tomographic static correction technology of undulating surface in the piedmont zone,employed prestack multi-domain noise suppression technology based on low-frequency fault surface waves protection,velocity modeling technology of high-steep structure in the piedmont zone and reverse-time migration technology of undulating surface,and thus improved the seismic imaging accuracy of complex structures in the high-steep structure zone in this area.As a result,large boundary fault zone characterization is more accurate,and the stratigraphic contact relation and structure imaging are clear.

Key words： high-steep structural zone piedmont zone static correction signal-to-noise ratio reverse-time migration
