Abstract: This paper presents the surface gholst reflection waves from VSP data in Tazhong desert area with varied relief and analyzes processing approach for deleting multi-ghost relection wave in full attenuation based on the characteristic of such a wave formed by surface structure in process of seismic prospecting or shot in Tazhong area. The study suggests that using VSP processing result integated with well logs can calibrate and recognize the full multi-ghost reflection waves of seismic profile, thus providing proper data volume for geologic researches in this area.

Key words: VSP data, ghost reflection, multi-wave, composite traces
