摘　　要：本文从分析VSP子波的基本特征入手,探讨了VSP子波反褶积的处理方法,指出了VSP子波反褶积处理参数的选择方法。利用VSP下行子波提取算子对VSP下行波、上行波和井旁地面地震剖面作反褶积均见到了较满意的效果。Starling from analyzing the basic characteristic of VSP wavelet, the processing technique for VSP wavelet deconvolution was examined. The technique for parameter election in data processing was given. By extracting the operator from the downgoing wavelet and using it to the deconvolution for upgoing and downgoing waves as well as the data obtained from the seismic profile passing though the well,satisfactory results could therefore be obtained.
