Бондарев В.И., Крылатков С.М., Курашов И.А.
In the previously proposed method of analysis of the wave field [3] was used transformation of source seismic traces to specially selected patch of observing area - Wide Bin, with subsequent accumulation. This technology allows to increase stacking fold of seismic data, and to conduct an effective separation of the observed field at the mirror and diffraction components. In the obtaining of mirror or diffraction seismic images of geological environment requires information about values of effective seismic velocities. It turned out that the determination of these velocities can be performed by the proposed method. The paper describes the algorithm of the velocity analysis, the obtained results compared with values of velocities, that determined by the standard CMP method of velocity analysis. Results indicates, that based on the proposed velocity analysis is possible to obtain seismic images of studied geological environment.
