Abstract：The paper presented a method of seismic-attenuated cross-hole tomographic imaging.Firstly, Using multi-scaled wavelet decomposition; then, using finite-difference algorithm of eikonal equation to compute the cross-hole seismic travel times and make inversion of cross-hole velocity structure;finally, using adjacent traces ratio method to eliminate the influence of source on imaging results, finishing the amplitude-attenuated imaging of common-shot gather records.The computation of cross-hole data, synthesized by high-order staggering finite-difference algorithm of viscous-acoustic equation of cavern-bearing layered model, showed that the precision of first breaks travel-time computed by the method is coincident with that by finite-difference of eikonal equation;the wavefield snapshots not only precisely describe the feature of seismic wavefronts in both forward and backward travel directions, but also quantitatively describe the energy transformation in a process of seismic wave propagation;the amplitude-attenuated tomographic imaging sections can accurately describe the size and position of caverns in model.
