Abstract
The research in the zones of no or weak record and investigation of lithosphere mainly uses wide-angle reflection and refraction seismic. In order to improve the processing quality of large offset seismic datasets, we can use some unique processing methods, such as non-hyperbolic NMO and corridor stack, etc. This paper mainly discussed some key techniques in wide\|angle reflection and refraction seismic and some existing problems based on the introducion of the progress of wide-angle seismic.
