摘要： 通过研究表层结构产生虚反射波的机理,在表层起伏变化较大的塔中大沙漠地区垂直地震剖面资料中得到表层虚反射波。据塔中地区地震勘探激发因表层结构产生的地表虚反射波特征,分析消除衰减全程多次虚反射的处理方法。利用垂直地震剖面处理成果结合测井资料,标定识别地震剖面存在的全程虚反射多次波,为地质研究提供准确的数据体。

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
