Duplex cable protector with rubber

Abstract

The invention discloses a duplex cable protector with rubber; the protector comprises an upper protector shell connected to two ends of a lower protector shell, the lower protector shell comprises clamping parts symmetrically arranged at two ends of a connecting part, abdicating plates are arranged on two sides of the connecting part, coupling clamping grooves are formed in the middles of the abdicating plates, and tubing couplings are mounted at the coupling clamping grooves. A plurality of first folding claws are arranged at the two ends of the clamping parts, a lower shell rubber sheet is arranged on the inner side of each clamping part, a cable groove and a pipeline groove are formed in the inner side of the lower shell rubber sheet, lower shell hinges are arranged on the two edges of each clamping part, and the lower shell hinges are connected with the upper protector shell. The upper protector shell comprises upper shell hinges arranged on the two edges of an arc-shaped plate; a plurality of second folding claws are arranged at two ends of the arc-shaped plate, upper shell rubber is arranged inside the arc-shaped plate, and a plurality of pipeline grooves and a plurality of mounting holes are formed inside the upper shell rubber. The rubber is arranged on the inner sides of the upper protector shell and the lower protector shell, so that the cable and the pipeline are effectively prevented from being affected by vibration, the clamping force is effectively prevented from being reduced, and the oil pipe and the cable are prevented from being abraded.

Description

technical field [0001] The invention relates to the field of oil drilling, in particular to a double-connected cable protector with rubber. Background technique [0002] In the process of oil extraction, the electrical equipment used must go deep into the oil production layer, the depth is generally hundreds or even thousands of meters, and the cable needs to be lowered to the same depth with the electrical equipment. During use, it is usually necessary to use a cable protector to protect the cable It is fixed on the oil pipeline for protection. In oil wells produced with submersible pumps, the cables that power the electric pumps and the hydraulic control lines for data acquisition are all lowered into the wells with the electric pumps outside the tubing. Since the running depth of electric submersible pumps is generally relatively long, that is, the length of cables and hydraulic control pipelines in the well is also relatively long, so it is necessary to protect the cabl...

Problems solved by technology

At present, the commonly used cable protectors for electric pumps are mainly divided into double protectors for the coupling part of the oil pipe and single protectors for the oil pipe body. If the structure of the cable protector body is simple and the method of use is single, it cannot meet At present, there is a demand for the use of the cable protector body for oil wells. In addition, the cable protector bodies for oil wells in the prior art are mostly independent structures due to their own design features.

[0004] In the prior art, the cable protector will loosen after vibration, which will affect the degree of clamping of the cable by the cable protector. While ensuring the degree of clamping, the clamping force may be too large. At the same time, due to The structural characteristics of the cable protector, when the cable protector slides along the cable, it will hang and pull the cable, causing it to be damaged. On the other hand, according to international and domestic standards, the outer diameter of the oil pipe is allowed to have an error of 3mm. Because the rigidity is sufficient but the elasticity is not enough, the clamping effect of the same specification tubing with different actual diameters is different, some can be clamped, and some can not be clamped, and the clamping effect on the cable may not be good.

Therefore, the existing cable protector cannot move within a certain range up and down the coupling, and it is difficult to effectively realize the clamping position if there is a slight error in production.
