DOWNHOLE SOURCE OF PLASMA-PULSE ACTION Russian patent published in 2016 - IPC G01V1/00 

FIELD: oil and gas industry.

SUBSTANCE: borehole pulse plasma source comprises a housing accommodating control unit, energy storage unit and plasma emitter, device for supply of metal conductor mounted on a separate base and including means of drawing metal conductor, motion transmission means and reel with metal conductor wound thereon. Device for supply of metal conductor is located in sealed housing and is configured for rigid connection with plasma emitter, means of drawing metal conductor is made in form of movable and fixed modules with U-shaped slots in which there are through recesses to accommodate guide plates, and at ends of protrusions there are lugs for attachment of axes therein, on which there are sharpened cams with torsion springs enabling swinging of cams on axis. Guide plates can move vertically and can be fixed in a preset position in through recesses of movable and fixed modules, and at ends of guide plates there are grooves for direction of metal conductor.

EFFECT: higher reliability of well source of plasma-pulse action.
