2the second step: Preparation for kinematic processingDetermining the kinematic parameters of the waves Kinematic parameters of the reflected waves are determined by calculating the horizontal stacking velocity spectra using a special local operator DHS. This can greatly improve the quality of the spectra (and thus determine the value and reliabilityVTransform). With highspeed analysis of network profiles, carrying it in layers in the system tallies time horizons, we have linked to the square root model and the corresponding agreed at the whole area of work, the effective parameters of the reflected wavest0 andVTransform. This technology allows for several advantages, in particular, in determining the kinematic parameters of the waves in the complex areas of interference, using the result of solving the inverse problem on the horizon. This allows the use of a priori geological information at the earliest and most critical stages of processing.
