- Аннотация: The implications of the Poisson ratio of a heterogeneity for the microseismic image of the latter reconstructed by the microseismic sounding method are studied in the numerical experiments. In particular, the cases are considered with anomalous effective Poisson ratios, which may probably occur if the microseismic waves propagate through fractured zones where the crack opening is commensurate with or larger than the characteristic amplitude of the vibrations. Based on the numerical simulations, the nonlinear distortions in the microseismic sounding method, which arise due to the perturbation of the microseismic (probing) signal by introducing the heterogeneities, are estimated.
