Abstract

On the basis of theoretical model of low-frequency acoustic vibrations effect on the oil-saturated porous reservoir, it Is shown, that at acoustic waves propagation in biphase fluid saturated porous hydrophilic media the existence of the additional damping mechanism, connected with a resonance absorption of a wave energy by a capillary-trapped part of residual oil. Is possible. The size of additional absorption factor depends on a wave frequency, reservoir parameters and a current reservoir oil-saturation in absorption zone. It is shown, that it is possible to determine the distribution of residual reserves on the area of an Investigated site and to specify a stage of its development, using system - a source in one well - receivers in the next wells.
