摘要

In the presented paper the results of the analysis of the influence of seismogeologicalmodel parameters as well as inversion parameters on the effectiveness of attenuation variations imag-ing by means of amplitude tomography based on the variations of centroidal frequency of signalspectrum in the seismic well to well measurements have been described. In the considerations the ho-mogeneous models with the zones of higher and lower values of velocity and attenuation as well asgradient media were taken into consideration. In the analysis of the effectiveness the centroidal fre-quencies of the signals observed in the receiver points and traveltimes generated for assumed modelswere used. The main attention was paid to the effect of starting velocity field on the results oftomographic inversion.
