Abstract:
Aiming to this problem that the feature of anisotropy is prominent and extensive for cross-hole seismic wave field and the conventional modelling method based on isotropy theory cant meet the needs of high accuracy and resolution imaging for cross-hole seismic data anymore, this paper theoretically analyzes the wave characteristic in VTI medium and presents a modelling method for VTI medium. Using the model established by this method, the modelling result of synthetic cross-hole seismic recorded by finite difference method is well coincident with the real cross-hole seismic records in both kinematical and dynamical characteristic, which proves the availability of this method.
