VIBRATION SEISMIC SURVEY METHOD Russian patent published in 2019 - IPC G01V1/28 G01V1/00 G01V1/02 

FIELD: geophysics.

SUBSTANCE: invention relates to geophysics and can be used for prospecting and exploration of mineral deposits. Disclosed is a method of vibration seismic survey, which includes excitation and recording of continuous signals, as well as subsequent cross-correlation of records with continuous reference signal (sweep signal). After correction of the reference signal using amplitude and phase spectra of signals recorded on the reactive mass and the support plate, oscillations are excited repeatedly. Method is characterized by that oscillations are repeatedly excited by sweep signal, said signal is converted to filtered signal by passing it through reverse filter formed by amplitude and phase spectra of signals recorded on reactive mass and support plate. Excitation of the filtered signal enables higher resolution of seismic records owing to elimination of distortions caused by excitation conditions. Besides, registration of oscillations on the support plate allows judging, on the basis of their spectra to the spectrum of the reference electric signal, the change in the excitation conditions when the position of the vibrating source is changed during the works and the stiffness of the rocks lying under the support plate is quantified.

EFFECT: high resolution of the method and additional information on physical properties of rocks located in the upper part of the section.
