- Аннотация: The work is devoted to creation of an anisotropic petro-elastic model (APEM) for detailed study of unconventional shale reservoirs (for example, the Bazhenov formation of Western Siberia, Russia) by seismic methods. The developed APEM, based on the theory of effective media, has allowed to obtain information on the distribution of elastic properties, the microstructure of pore space, and to calculate the Thomsen anisotropy parameters of the studied sediments. Based on the results obtained a petrophysical substantiation of the perspective intervals delineation using a cross-plot acoustic impedance - Vp/Vs ratio was carried out. The AVO analysis performed on the model and real data showed the influence of VTI-anisotropy on AVO-responses for the target interval. The calculated anisotropy parameters should be taken into account when seismic amplitude inversion is performed to obtain a more accurate estimates of the elastic properties and increase the reliability of the seismic forecast.
