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.
