The Model of Oblique-Layered Media - the Reserve on the Way to Enhance the Reliability of Two-Dimensional Seismic Images

Provides a method of processing multifold coverage data based on the use of models with inclined reflective border. It uses the notion of local fragment of the reflecting boundary in the studied section.

Discusses the line of centers of these sites - the-line points of reflection, as centers of accumulation transferred in the seismic amplitudes. Discusses in detail a set of traces collected on the principle of the community of their common points. We present the necessary formulas to obtain the coordinates of the reflection point for the selected set of seismic traces. The results of constructive interference of amplitudes they characterize the reflective properties of the geological section in the area of environmental protection and represent the migrated image of part of the environment.

This method allows of obtaining depth and time-migrated seismic images of the section on the results of standard seismic works by the method of multifold coverage CDP-2D. In the process of constructing seismic images of geological environment under difficult conditions, the proposed method allows you to more objectively consider the various possible angles of tilt of the reflecting boundaries in depth and profile of the study.
