FIELD: the invention refers to seismic prospecting and may be used at prospecting oil and gas deposits.
SUBSTANCE: the invention includes multiple execution along the factors of a common point of reception , a common point of excitation, a common middle ( depth) point and a common removal of two-dimensional filtrations in F-K and F-X fields in a high frequency ( more than 90-100 cycles per second) band of a database (seismograph of a common point of excitation, a common point of reception, a common middle ( depth) point and a common removal of two-dimensional filtrations) of wideband dynamic time cuts with maximum weakening of seismic noise and all axles of coherence connected with nonhorizontal boundaries. In the mode all left subhorizontal boundaries are intensified for accurate apportionment and special position of chosen boundaries is determined according to totality of all time cuts on the square.
EFFECT: increases informative functions of the mode.
