The Processing Method Of Wide-angle Seismic Reflection Data And Inversion Of The Crustal Structure

Seismic reflection was one of important methods of investigating deep crustal structure , which was applied from oil-gas and mining in the inner earth. Due to the improvement of seismic prospect equipments and application of new collecting methods, seismic collection was developed from the initial some hundreds to several thousands traces, and even up to ten thousands traces in the last ten years, which caused the expanding application for the wide-angle seismic exploration. Nowadays, wide-angle seismic prospect has a significant effect on imaging of geologic targets in deep crust.To study geologic targets by the common technologies of seismic exploration, reflections of seismic data collected usually were interfered by multi-order reflections and refractions. Therefore, correct imagings could not be got with their low signal-to-noise ratios. However, it may be overcome by wide-angle seismic prospect. Because the partition between one-order valid reflections and interferential signals in far angle stacks by wide-angle seismic prospect was realized, so, the...
