Abstract

The invention relates to an externally-attached optical fiber oil-submerged pump cable, which comprises a cable body, and is characterized in that the cable body comprises wire cores and an optical fiber; each wire core comprises a copper conductor, and a polyimide film insulating layer and an ethylene propylene diene monomer insulating layer are sequentially arranged outside the copper conductor.A wrapping F4 film isolation layer and a colored nylon cloth cushion layer are sequentially arranged outside the ethylene propylene diene monomer insulating layer; the plurality of wire cores form acable; a nitrile rubber inner sheath layer and a first outer protective layer are sequentially arranged on the outer side of the cable. The optical fiber is provided with a steel pipe sheath; and a second outer protective layer is arranged outside the first outer protective layer and the optical fiber provided with the steel pipe sheath. According to the externally-attached optical fiber oil-submerged pump cable, the first outer protective layer and the second outer protective layer are steel tape armors, the optical fiber with the steel pipe sheath is placed between the double protective layers, and the externally-attached structure enables the processing technology to be simpler and more convenient; occupied oil extraction pipe space is reduced, an optical fiber control signal line and an oil-submerged pump cable can be successfully laid at the same time through one-time operation, laying time is shortened, the operation cost is reduced, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to a submersible oil pump cable, in particular to a submersible oil pump cable with an external optical fiber. Background technique [0002] The use occasions and requirements of submersible pump cables are different, and the use characteristics and requirements of submersible pump cables are also different. Because the space in the pipe of the oil production well is limited, the maximum reasonable use of the space in the production pipe is the new development direction of the submersible pump cable. Ordinary submersible pump cables have the following technical problems: the function is relatively single, and can only transmit electric energy; the structure is simple, the resistance to external mechanical After being damaged by external force, vibration, etc., the service life will be shortened. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention provides an exte...
