FIELD: mining.
SUBSTANCE: logging device is placed into a shaft of a well drilled via a porous medium, which is filled with a well fluid, pressure p(I) of an acoustic wave is measured in the well shaft near the border between the porous medium and the well shaft, at the same time the acoustic wave has frequency close to resonant frequency of the system, comprising a well shaft and a porous medium, permeability is calculated on the basis of pressure, and the user is provided with permeability data in the form of output data.
EFFECT: higher accuracy of measurement of rocks permeability.
