In the mountains, the Gobi Desert complex areas such as seismic exploration, seismic static correction data processing technology is the key. Surface elevation in these complex areas changes, changes in the surface rocks are very sharp, low-velocity layer thickness variation, shooting and receiving conditions and complex near-surface conditions caused by rapid change, vertical and horizontal. In this paper, according to the geological characteristics of Northern edge of Junggar Basin, which is complex. Use chromatography to solve the near-surface model which contain both the advantage of the first as the preliminary wave and the flexibility of rotating wave inversion. Solve the problem of long-wavelength static correction better and improve quality and increase signal to noise ratio when use chromatography statics.
