FIELD: geophysics.SUBSTANCE: invention relates to geophysics and can be used during seismic data processing. Disclosed is a method for deep profiles of geologic environment q-factor by seismograms (92) of equal distances of seismic data of reflected waves by performing migration (40), ray tracing (100), location (96, 98) of lifting angles from the common depth point to the surface, drawing up (110) a nuclear matrix. Method also includes depth-time conversion, correction (80) for influence of seismic pulse stretching, approximation of the source amplitude spectrum, calculation (90) of centroid frequency shift and optimisation (120) bound by box restrictions.EFFECT: technical result is increased accuracy and reliability of obtained data.11 cl, 18 dwg |
