Abstract: The tomographic inverse technique for near-surface model is a model to be used for inversing various media velocity from subsurface and near-surface by means of seismic first arrival time and seismic ray-tracing method in order to obtain subsurface seismic velocity and corresponding depth information at geophone spots as required and develop corresponding surface structural models. According to these, we can get static correction values of shot point and acceptance point so that eliminates influence from static corrections and improve resolution of seismic reflecting wave for gaining high quality of seismic profiles.

Key words: first arrival, tomographic inverse, static correction, seismic ray tracing, bow tie
