Propagation of seismic waves in inelastic thin-layer media

Abstract

We obtained complex interference characteristics of reflection and refraction through the pack of absorbing layers of elastic P- and S-waves as functions of incident angle and frequency. The algorithm proposed is realized in the program of modeling allowing both to estimate frequency and phase characteristics of reflection and propagation of P- and S-waves for the given number of absorbing layers in the pack and to construct corresponding synthetic seismograms. The example of applying the program developed for the quantitative estimation of possible AVO-effect in the productive interval of the section of Varavenskaya area is given.
