PROTECTOLISER FOR PROTECTION OF POWER EXTENSION CABLE IN WELL

摘要

FIELD: oil and gas industry.SUBSTANCE: invention is referred to the oil and gas industry and may be used for the protection of the power cable for a pump from mechanical damage in the process of the tubing hanger trip with the installation of an electric centrifugal pump in vertical, directional and horizontal wells. The invention claims a protectoliser consisting of a two-component case and a detachable tool joint with fastening elements. The case consists of an articulated case with a cable duct and a bracket. The protectoliser case and the bracket are interconnected by a swing bolt and an adjusting screw screwed into the case and connected to the bracket by an axle. The adjusting screw may be regulated axially due to screwing in/out into/from the case when the diameter of the pump neck changes. The protectoliser case in the cable duct is equipped with a compensating spring support for the regulation of the slot size for the power cable. The detachable tool joint is made as a hinged bolt and a nut with a spring lock to prevent uncontrolled turning off.EFFECT: improving the reliability of the protectoliser fixation at the pump neck; improved universality of the protector.2 cl, 5 dwg
