Due to the violent surface fluctuation and the lateral variation of the low velocity layer,the static correction is the key and difficult part of seismic data processing in such areas.The method of tomographic static correction is widely used in the field of seismic data processing by using the travel time and path of the first arrival wave to build the medium velocity structure,which is not restricted by vertical and horizontal changes of the near surface structure and the surface.This paper gives a brief description of the technology of man-machine interaction and automatic tomography,and describes the realization process of the two technologies.Combined with the actual data of the northern Ordos area,the authors carried out a comparative study of the application effect about seven indicators,i.e.,the first arrival wave picking,inversion model,the static correction,the residual static of reflected wave,the profile,the closed error and the long-wavelength static correction.The differences between the two technologies are explained, which provides the basis for selecting the practical and efficient static correction technologies for seismic data processing.
