Abstract：AVO phenomenon relating to petrophysical parameters can be seen in both compressional wave and shear wave. Basic AVO analysis of P-SV and SH waves has been done in the procedure which is similar to that for compressional wave AVO analysis, namely.starting from a series of allowable reduction of the Zoeppritz's e-quations to get some formulae which have geological and seismic attributions. Research result leads to the conclusion that the seismic property of SH wave can be derived from P-SV wave, and that slightly-revised AVO analysis software for compressional wave can also be applied to AVO analysis of shear wave. A series of modeling computation says that AVO analysis for shear wave is very potential.
