INFLUENCE OF VIBROWAVE ACTION ON THE CHARACTER OF PRESSURE DISTRIBUTION IN A PERMEABILITY-INHOMOGENEOUS BED

Based on theoretical investigations, the infl uence of different kinds of generator-produced elastic waves on the character of change in the bottomhole pressure has been studied with account for the bed deformability. An analytical expression has been obtained allowing one to determine the dynamics and depth of elastic wave propagation in the bed with account for the bed collector deformation. It is shown that the degree of attenuation of elastic waves in deformable collectors increases considerably as against undeformable ones.
