FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil production. The device includes the lengthy protector made as the long-length stout cylinder with the installed inside core rod which has the output from protector at the side of its contact with the bottomhole equipment. The core rod has the supplemental output from the protector, opposite to the first output. The supplemental output is lengthy, bent towards the bottomhole equipment, placed lengthwise the protector and the bottomhole equipment to its upper part.
