METHOD FOR VIBRATION SEISMIC SURVEY Russian patent published in 2015 - IPC G01V1/00 G01V1/36 

FIELD: physics.

SUBSTANCE: method for vibration seismic survey is based on exciting and detecting seismic vibrations and includes correcting excited signals by varying the relative intensity of the spectrum component for waves of interest. The invention proposes further detection of vibrations in at least one well at a depth greater than the depth of the sharpest acoustic interface located at each area in the region of investigation, characterised by a homogeneous structure of the upper part of the section. The invention proposes to use a vibration record, obtained from a seismic detector within the medium after correcting the excited vibrations by analysing the spectrum of said vibration record, as a reference signal for converting vibration records recorded by surface seismic detectors or well seismic detectors into a pulse form.

EFFECT: high quality of vibration seismic survey data.
