Abstract: Problems of interpretation of spectra acoustic signals, registered by multi-element well-bore probes, are considered. Basing on M.A. Bio theory of acoustic waves propagation in saturated porous media, the authors propose an algorithm of calculation to determine physical and mechanic parameters of rocks. The results of pretesting using production data are presented. The presented approach can be adapted for a wide range of tasks of ultrasonic measurements of porous media parameters.
