Summary:
The technology for determining the angular parameters of the reflecting boundaries by the data of the CDP 3D for the purpose of subsequently taking this information into account when constructing a seismic image of the geological environment and forming arrays of new attributes of seismic wave fields. The basis of this technology is the original way of asymmetrical formation of seismograms of the new type. After the introduction of special kinematic corrections to these seismograms, it becomes possible to determine the values of azimuths and the slope angles of the boundaries as a function of the depth or time of reflection on the basis of an adjustable directional analysis of the residual wave field.
