FIELD: geophysics.
SUBSTANCE: invention relates to geophysics and can be used in seismic surveys. Describing is method for seismic prospecting. Method uses plurality of groups of vibrators for seismic exploration using low-frequency and high-frequency vibrators in each group of vibrators. Multiple groups of vibrators continuously send low-frequency sweep signals by means of low-frequency vibrators. During sending of low-frequency sweep signals vibrators emit high-frequency signals in staggered order between groups of vibrators to increase range of seismic survey.
EFFECT: technical result is improved accuracy of obtained data.
