Description

Technical Field

[0001] The utility model embodiment relates to the technical field of cable protectors, and in particular to a downhole oil pipe coupling cable protector. Background Art

[0002] In oil well operations, the power cable, control pipeline and chemical injection pipeline of the submersible pump are connected to the power supply of the working surface and the submersible pump at the bottom of the well through the wellhead along the oil production pipe. In order to prevent the cables and pipelines from being broken due to excessive gravity concentrated at a certain point, it is necessary to use a tubing coupling cable protector to protect the power cable; for example, as shown in the downhole test cable protector through the working barrel with Chinese patent application number CN202020868890.9, special couplings are installed above and below the working barrel for axial and angular positioning of the protector; the protector is divided into upper and lower sections, which are processed and stored separately, which not only fixes the protector axially, but also ensures that the protector will not rotate and affect the safety of the cable.

[0003] However, since the centralizer separates the oil pipe from the inner wall of the casing to achieve the straightening of the oil pipe and thus prevent the cable pipeline from being squeezed, rubbed and damaged, the centralizers on the market do not have the function of fixing and protecting the power cables and pipelines at the same time and have poor impact resistance; therefore, in actual operation, the power cables and pipelines are very easy to be damaged and worn, causing serious danger.
