Abstract
The utility model relates to a cable, and especially relates to a buffer type electric submersible pump power cable which is capable of resisting 204 DEG C. The technical scheme is that the buffer type electric submersible pump power cable includes conductors, insulating layers arranged on the surfaces of the conductors, thermosetting resin linings, lead sheathes, and a steel belt interlocking armor layer; the insulating layer combines an FHF film sintered insulating layer and an FEP extruded insulating layer; the thermosetting resin lining is arranged between the insulating layer and a single core lead sheath. A plurality of conducting insulating wire cores is arranged in parallel, and the outside of the conducting insulating wire cores is provided with the interlocking steel belt armor layer. The beneficial effects are that: after the structure improvement, the buffer type electric submersible pump power cable can work normally when the well temperature is more than 180 DEG C, and the service lifetime and the performance can reach to the using requirements; the insulation performance of the cable in use is guaranteed via the combined insulation mode, and the duel protection of the cable is realized through arranging the linings, so the problem that a conventional material is easy to break by a mechanical damage caused by the substandard temperature resistance level can be solved.
Description
Technical field
The utility model relates to a kind of cable, 204 ℃ of electric submersible pump power cables of particularly a kind of buffer-type heatproof.
Background technology
Prior electric oil-immersed pump power cable is realized the insulation property of cable with the film sintered combining form that adds above several kinds of insulating material of PP, EPDM, FEP, PFA or FHF; With the butyronitrile poly (vinyl chloride) blend; Acrylonitrile-butadiene rubber, different materials such as EPDM rubber, lead are as sheath.Be lower than 120 when spending at downhole temperature, adopt above insulation form can also satisfy instructions for use, reach 180 when spending, then need normal phase working temperature to reach the insulating sleeve material of phase 204 degree in the well temperature.But FEP, PFA are during as insulation and sheath material, and processing thickness is too thin, and the poor-performing of anti-mechanical-physical damage influences the useful life and the performance of cable greatly.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, provides a kind of buffer-type heatproof 204 ℃ of electric submersible pump power cables, and it can normally be used when the well temperature is spent greater than 180, and useful life and performance can both satisfy instructions for use.
Its technical scheme is: comprise the insulating barrier of conductor, conductive surface, thermosetting resin lining, lead sheath and steel band lock armo layer; Described insulating barrier adopts the film sintered insulating barrier of FHF, the combination of FEP extruded insulation layer, and between insulating barrier and single core lead sheath, adds one deck thermosetting resin lining, and many conduction insulated wire cores are arranged in parallel, and adds union lock steel-tape armouring layer.
Above-mentioned single core lead sheath is provided with wrapped oil resistant layer outward.
The beneficial effect of the utility model is: structure can normally use it through improvement when the well temperature is spent greater than 180, and useful life and performance can both satisfy instructions for use; Guarantee cable insulation property in use through the combined insulation form, adopt the form that adds lining to realize the duplicate protection to cable, solved the conventional material temperature resistant grade and do not reached requirement, exotic material runs into the problem that mechanical damage punctures easily.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: the film sintered insulating barrier of conductor 1, FHF 2, FEP extruded insulation layer 3, thermosetting resin lining 4, lead sheath 5, wrapped oil resistant layer 6, steel band lock armo layer 7.
Embodiment
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model comprises the insulating barrier of conductor 1, conductive surface, thermosetting resin lining 4, lead sheath 5 and steel band lock armo layer 7; Described insulating barrier adopts the film sintered insulating barrier of FHF 2,3 combination of FEP extruded insulation layer; And between insulating barrier and single core lead sheath 5, add one deck thermosetting resin lining 4; Many conduction insulated wire cores are arranged in parallel; Add union lock steel-tape armouring layer 7, be provided with wrapped oil resistant layer 6 outside above-mentioned single core lead sheath 5.
During making, adopting single real core copper free wire is conductor, and the wrapped sintering of FHF film is as the ground floor insulating barrier, and FHF is film sintered, FEP extrudes continuous production, as complete insulating barrier; Continuous vulcanization mode processing thermosetting resin squeezes plumbous form continuously and adds lead sheath as lining, the wrapped wrapped oil resistant layer of fabric strip that adds of PTFE film, and three conduction insulated wire cores are arranged in parallel, processing interlocking steel-tape armouring layer.
The insulation form that this cable is selected for use is that FHF is film sintered, FEP extrudes combined insulation; And the adhesivity that carries through the FHF film is one with two kinds of materials bondings; The normal phase working temperature of these two kinds of materials is all more than 204 degree; Process one deck thermosetting resin then and do this lining, adopt lead to make sheath.Guarantee cable insulation property in use through the combined insulation form, adopt the form that adds lining to realize the duplicate protection to cable, solved the conventional material temperature resistant grade and do not reached requirement, exotic material runs into the problem that mechanical damage punctures easily.
The utility model is simple and reasonable, adopts conventional processing method to manufacture, and serviceability is good.Conductor adopts anaerobic electrician circular copper wire, and the transmission performance of cable is stable, and combined insulation is adopted in insulation, and bonding firmly has good insulation performance performance and sealing property between conductor and the combined insulation.Processing buffer lining between lead sheath and insulating barrier guarantees that cable insulating barrier when running into external force does not sustain damage.Sheath employing oil resistance, the metallic lead that thermal conductivity is stable, the insulation property of assurance cable and oil resistant, decay resistance can normally use cable under high-temperature severe environment.
