Abstract
Studies of propagation and diffraction of waves in the medium with wells are an urgent task in geophysics and geology. The present work is devoted to studying a cylindrical reinforced well with a liquid located in a viscoelastic medium. It is shown that the wave field observed in the well can be represented by a combination of different waves (hydro waves, water), differing in characteristic dispersion, spectrum behavior, and field distribution along the radius of the well. Dispersion curves of phase and group velocities are calculated for media with different viscoelastic parameters. It is found that at cutoff frequencies, transverse waves have abnormally low attenuation. It is revealed that at low phase velocities (hydro waves), with increasing wavelength, the real and imaginary parts of the phase velocity monotonically increase.
