FIELD: oil and gas industry.
SUBSTANCE: invention may be used for protection of the pump power cable from mechanical damage in the process of tubing string TBG hanger trip with installation of the electric centrifugal pump in vertical, directional and horizontal wells. The multi-purpose protectolizer for protection of the power extension cable in the well contains the two-piece housing, the detachable locking connection with the fastening elements. And the case consists of the hinged articulated case and fastener, in addition, the protectolizer case and fastener are connected together by the hinged bolt and the adjusting screw, screwed into the case and connected to the fastener by means of the axis. The adjusting screw has the ability to be regulated axially due to screwing into/out the case, when diameter of the pump neck changes. The detachable tool joint is made as the hinged bolt and the hold-down nut with the lock washer to prevent the uncontrolled screwing. In the upper part of the case there is the open longitudinal groove on one side, into which the electric cable is layed, fixed in the groove by the clamping bar with the screw. In addition, in the upper part of the case there are made the transverse double grooves to position the studs and nuts of the submersible motor (SEM) housing in it.
EFFECT: increase of the protectolizer reliability at the UCN and SEM flanges and increase of the device versatility.
