BOREHOLE SEISMIC SOURCE Russian patent published in 2021 - IPC G01V1/135 

FIELD: vibroseismic technology.

SUBSTANCE: invention relates to vibroseismic technology and can be used to increase reservoir recovery of oil and gas fields by generating and transmitting seismic vibrations to oil-containing reservoirs, as well as for seismic exploration of the earth interior. A borehole seismic source is claimed, in which each of the power devices is made in the form of an elastic chamber with an oil-filled cavity located in the body of the power device. Moreover, the elastic chamber is connected along the outer surface with orthogonally movable wedges and punches, on which there are pads mounted in the holes of the housing with the possibility of radial movement. Moreover, the plunger is connected to an elastic chamber, and the device is equipped with a converter with an elastic diaphragm designed to separate oil-filled cavities connected by pipes from the elastic chambers of the upper and lower power devices.

EFFECT: creation of a device that allows the compatibility of the operation of a borehole seismic source with the technology of oil reservoir flooding.
