Abstract：As one of difficult seismic-geological conditions, the alternating sand-mudstone and limestone outcrop areas is a tight problem for mountain seismic exploration. We present in this paper a method of tomo static corrections for dramatic variations of topography, surface lithology and structure. To improve the signal to noise ratio of limestone outcrop areas, we propose some new idea for noise removal. For strongly anisotropy of alternating sand-mudstone and limestone outcrop areas, we jointly use an anisotropic velocity analysis, optimized trace stacking, and residual static correction. Therefore imaging is much improved. Highly accurate velocity model based on quality trace gathers will provide a good foundation for prestack depth migration.
