Abstract
A method for determining the angular parameters( angles of incidence and azimuths of incidence) of seismic boundaries using standard 3D seismic survey materials is described. This makes it possible to more effectively analyze the history of sedimentation in the studied geological strata. The solution of this problem is carried out for the General calculation points (CMP) selected on the research area. It is assumed that the nature of changes in the depth of the values of the effective propagation velocity of elastic waves is known from the observation profile. Under these conditions, based on the use of a set of source routes of seismograms of common excitation points, you can select special collections of seismic routes that are United by a common reflection point for them at seismic boundaries.
