Nonlinear deformation-wave processes in the vibrational oil geotechnologies

The paper explains a number of phenomena that are observed in the surface vibrational treatment of oil and gas reservoirs based on the thriving theory of pendulum waves, e.g., a ring-shape response of a productive stratum and a time lag in the response, seismic luminescence and its spectrum, etc. The authors give data on velocity groups of pendulum waves in stressed block hierarchy of rock masses and substantiate the choice of the wave velocity group to be generated by the powerful surface vibro-sources designed at the Institute of Mining. The theoretical and phenomenological formulas given in the paper are of assistance in the development and improvement of the surface vibrational technologies for the enhancement of oil and gas recovery.
