| Abstract: | In order to cope with complicated surface condition in Kumutake desert in theDunhuang basin, we derive surface-layer structure data from minor refraction data,first break times of normal seismic records and elevation corrections. Three staticsmethods (minor refraction modeling, extended generalized reciprocal and firstbreak inflection plus continuous refraction velocity inversion ) were tested widely.Theoretical data analysis and real data processing result show that the third methodis a desirable static correction method in the desert area. The method has been usedto achieve the static correction of 1300 km seismic data in the area, bringing goodeffect. |
