Abstract: In theory, the present tomographic static correction technique can be used to deal with the inversion of surface structure model under any complex surface condition. Because of the influences of field acquisition geometry design, initial model, equation solutions and smoothing factor, etc, the precision of tomographic inversion model and static correction still fails to meet the need of seismic imaging of such a complicated exploration area. Aiming at the problems of lower high?frequency precision, border effect and cross?point closure existed in application of tomography to complex surface area, this paper describes a series of methods applied in actual data processing, based on the surface structure characteristics in Fujin basin, and the distinctive effect indicates that the imaging quality of seismic data processing has been further improved, and the technique may be popularized for application to the other similar complex exploration areas
