BOREHOLE SEISMIC VIBRATOR Russian patent published in 2023 - IPC G01V1/153 G01V1/40 

FIELD: vibroseismic equipment.

SUBSTANCE: used to enhance oil recovery of oil fields by borehole vibration impact on oil reservoirs. A borehole seismic source placed in a casing pipe, containing a housing with at least one power element, with orthogonally movable wedges, punches with overlays, elastic chambers connected by nozzles with an oil-filled cavity of the pressure transducer, feeding an electric cable. In this case, the body is made in the form of at least two sliding longitudinal sectors of the hollow cylinder, with opposite edges fixed on the plates coaxially mounted punches located in the same vertical plane with the longitudinal axis of the power elements. At the same time, at least one unbalance vibrator is rigidly mounted on the inner surface of each sector of the hollow cylinder, on its longitudinal axis.

EFFECT: creation of a seismic source of a reliable design that increases the flow rate of the well by increasing the area of impact on oil-bearing formations and directing vibration pulses perpendicular to the longitudinal axis of the casing in a circular range, with full transmission of mechanical energy power.
