Analysis of wave-field abnormality of big offset VSP data (in Chinese)

Bigger offset results in wider VSP image extent and better VSP application. However, there follow two disadvantages, some wavefield abnormality of raw VSP data and increased stretching distortion in VSP-CDP transformation. The casual relation between big offset and VSP first-arrival abnormality or wave group interference is analyzed using the VSP data from well NU34. Suggestions on avoiding wave-field abnormality and designing optimum VSP offset are made by the authors of this paper.
