FIELD: geophysics.
SUBSTANCE: invention relates to geophysics and may be used in seismic data processing. Method of anisotropy parameters determination is proposed, which includes providing information on slowness of longitudinal and transverse waves in a homogeneous, anisotropic formation in the inclined well with inclination angle of more than 40 degrees and less than 90 degrees, as specified by transversal isotropy with vertical axis of symmetry (VTI), providing the relationship between normal and tangential compliance, and, on the basis of these data and relationship making a model for calculating parameters of anisotropy (for example, α0, ε, δ), which characterize uniform, anisotropic formation (for example, along the well at an angle of 90 degrees). Various other devices, systems, methods, etc. are also disclosed in this application.
EFFECT: technical result is improved accuracy of obtained data.
