The surface and underground structure of the plateau are complex and changeable, and the static correction problem is distinct. Through years of exploration, the authors gradually formed a series of static correction technologies for plateau salty surface construction: the initial model of complex surface; extremely low SNR standard layer static correction technology; high steep structure comprehensive static correction technology; static correction, surface gun domain iterative detection of saline desert flow; the original surface refraction static correction technology. This series of static correction technologies can effectively solve the problem of static correction in the Western Plateau under the condition of saline land surface. It has played an active role in improving the signal-to-noise ratio and the image quality of the surface seismic data.
