FIELD : oil and gas industry.
SUBSTANCE : device comprises at least one matched pair of coupled magnets of opposite polarity from rare-earth metals. Each magnet has radially internal and external bent surfaces passing along the axis in longitudinal direction and ending in transverse direction to form a pair of flat surfaces coupling the specified bent surfaces. Each magnet is diametrically charged and has internal and external bent surfaces of identical polarity, and a pair of flat surfaces of identical polarity, but opposite to the polarity of bent surfaces. A pair of magnets is coupled by means of matching of flat surfaces. At the same time the magnets form a hollow cylinder. A fluid leaks inside or outside the cylinder. The device additionally comprises a system of well operation with a sucker-rod pump, having pump rods moving in a discharge pipeline for leakage of the fluid that surrounds at least one pair of coupled magnets.
EFFECT : higher efficiency of impact at the fluid, simplified design.
