Abstract
ACOUSTIC PSEUDO-IMPEDENCE LOGS FOR VARIOUS MODELS OF SEISMIC STRUCTURE OF ROCK BUILDUPS
Summary
The factors, limiting an usage of "sejslog" method and effecting considerably on quality and credibility of calculated pseudo-impedence logs were discussed here. The phenomena of limited frequency band of entered signal was regarded in synthetic seismograms, using signals of broad and narrow amplitude spectrum. The pseudo- impedence logs were calculated for models of various types of seismic structure of rock buildups. The results were illustrated on figures, where such features as: curve ρ • v (estimated on model parameters), synthetic seismogram, pseudo-impedence logs as well as curve of reflection coefficients were drown separately for any regarded structural model.
