Фильтрация сембланса при обработке записей волнового акустического каротажа

Ахметсафина Р. З., Ахметсафин Р. Д.

Semblance or slowness time coherence is a measure of the coherence of energy distribution be-tween recorded signals at antenna array receivers of acoustic wave logging probe in the coordinates "the reduced time of the wave path from the middle of the antenna array” — “interval time". Several semblance filtering methods are proposed to allow for elimination of the effect of aliasing and to separate the wave packet components.
