METHOD FOR VIBRATING SEISMIC EXPLORATION Russian patent published in 2022 - IPC G01V1/00 G01V1/02 G01V1/28 

FIELD: vibration seismic exploration.

SUBSTANCE: method for vibration seismic exploration is based on the excitation and registration of vibrational seismic vibrations and includes the correction of the excited signals by increasing the relative intensity of the waves of exploration interest. It is proposed to preliminarily select a train of incident waves from the entire wave field by observing in a borehole on a longitudinal vertical profile and then use it as a reference signal for cross-correlation or deconvolution of VSP seismic records. The use of a train of incident waves allows, with cross-correlation with it or with deconvolution using this train as a reference signal, to suppress multiple reflected waves contained in the wave seismic field. Upward waves identified after cross-correlation or deconvolution will contain only single reflections, so the amplitude-phase correction of the sweep signal based on these waves will be more reasonable and reliable. Under the same type of seismogeological conditions of the area studied by the vibroseismic survey, the signal corrected by the proposed method will be entered as a user signal into the control systems of the vibrosource and will be applied in the development of the entire area of ​​the region. To introduce the method into production, it is proposed to use existing technical means designed for adaptive vibrational seismic.

EFFECT: improving the quality of vibration seismic data, providing a higher reliability of geological results.
