FIELD: the invention refers to seismic prospecting precisely to modes of carrying seismic prospecting works with application of non-explosive surface sources. ^ SUBSTANCE: the mode includes separation of a geological cut on depth floors, computation for each floor and location on the terrain of a system of reception of seismic signals distinguishing between themselves with a pitch of receiving channels, excitation of waves by sources, reception and registration of the wave field. New in it is that according to the results of computation a system of reception of seismic signals is picked up. The system is tuned on the depth floor rendering the outmost distorting influence on the wave field of the depth floors lying below and the receiving channels in this system and the sources are located on the terrain with an identical pitch. At that the excitation of waves is made at least by two seances . In one of them the excitation of waves is made by all sources simultaneously and in the other seance the excitation of waves is made successively with each source. ^ EFFECT: increases efficiency and accuracy of prospecting works. |
