Abstract
The utility model relates to a double-sheath round cable for an electrical submersible pump. Round cable has the defects that: as a lapping outer insulating layer has poor oil corrosion-resistant function and can not prevent gas pickling, the ageing of the insulating layer of the cable is accelerated due to corrosion in use, and the cable can not be recycled after losing effectiveness, therefore, resource waste is great, and the production cost for oil extraction is increased. For the double-sheath round cable, the insulating layer (2) of a conductor (1) is externally wrapped with a sheath layer (3) which is a wire core in an extrusion way; three wire cores are arranged in a triangular form and then wrapped by a rubber sheath (4), and an armor layer (5) is arranged outside the rubber sheath (4); and the sheath layer (3) is made of fluoroplastics. The double-sheath round cable has the benefits of being simple in structure, practical in function, high in reliability and prolonged in service life, and preventing the insulating layer of the cable from being corroded by underground environment.
Description
Affiliated technical field
The utility model relates to a kind of petroleum recovering machinery equipment oil-immersed pump unit cable, especially relates to the circular submersible electric pump cable of a kind of pair of sheath.
Background technology
Submersible electric pump is widely used in field of petroleum exploitation, and submersible electric pump cable is to be the matching used power cable of oil-immersed pump unit, and the lower end links to each other with jump lead, and the upper end is connected with the Ground Control cabinet, is laid in the oil well.Submersible electric pump cable requires the corrosion resistance of cable good, good airproof performance because operational environment is more abominable, guarantees that well liquid can not infiltrate in the insulating barrier; Heat resisting and pressure resisting is good, the long-term operate as normal of energy under down-hole high temperature and pressure; Higher mechanical strength is arranged, in case in the process of removing, damage.
Existing submersible electric pump cable circle cable is made up of conductor, insulating barrier, restrictive coating and armouring tape, as disclosed Chinese utility model patent on June 4th, 2008 " electric submersible pump electric power circle cable " (publication number CN201069677), this cable comprises conductor, inner insulating layer, external insulation layer, sheath and armour; Conductor is outside equipped with inner insulating layer, the arranged outside of inner insulating layer has external insulation layer, and conductor, inner insulating layer are formed an independently signal transmission core, and three identical signal transmission cores are coated by sheath, outside at sheath is provided with armour, and the outer surface of armour is continuous semicircular arc.
External insulation layer in the submersible electric pump cable circle cable all adopts wrapped mode.Contain hydrogen sulfide (H in the part oil well at present
2S), carbon dioxide (CO
2) wait sour corrosion gas or have corrosive liquids such as bittern water, though adopt the cable of wrapped external insulation layer can effectively stop the infiltration of solid molecule, but be difficult to the erosion of opposing down-hole oil and gas environments, corrosive gas in the oil well and small-molecule substance can penetrate rubber sheath insulating barrier is corroded, cause insulating performance of cable to reduce, even lost efficacy in advance, and can't recycle behind the cable failure, greatly waste resource, increase the oil recovery production cost.
The utility model content
For the wrapped external insulation layer that overcomes the existence of existing circle cable prevents that oils erosion function is poor, and can not prevent gas pickling, cause the cable insulating barrier accelerated ageing that is corroded in use, and can't recycle behind the cable failure, greatly waste resource, increase the deficiency of oil recovery production cost, the utility model provides a kind of pair of sheath circular submersible electric pump cable.
The technical scheme that its technical problem that solves the utility model adopts is: the circular submersible electric pump cable of two sheaths, comprise conductor, insulating barrier, restrictive coating, rubber sheath and armour, it is the single line core that conductor outer wrapping insulating barrier, the insulating barrier of conductor are extruded with restrictive coating outward; Three core triangularities are arranged the back by the rubber sheath coating, and rubber sheath is outside equipped with armour; The material of restrictive coating is fluoroplastics.
The beneficial effects of the utility model are, and are simple in structure, function is practical, reliability is high, prolong useful life, guarantees that cable insulation is not corroded by subsurface environment.
Description of drawings
Fig. 1 is the circular submersible electric pump cable structural representations of the two sheaths of the utility model.
Among the figure: 1. conductor, 2. insulating barrier, 3. restrictive coating, 4. rubber sheath layer, 5. anti-armour.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to accompanying drawing.The circular submersible electric pump cable of the two sheaths of the utility model comprises conductor 1, insulating barrier 2, restrictive coating, armour 5, conductor 1 outer wrapping insulating barrier 2, and the insulating barrier 2 outer restrictive coatings 3 that are extruded with are the single line core; Three core triangularities are arranged the back by rubber sheath 4 coatings, and rubber sheath 4 is outside equipped with armour 5; The material of restrictive coating 3 is fluoroplastics.
The utility model adopts the duplex sheath structure that insulating barrier is protected; the fluoroplastics restrictive coating that extrudes at insulating barrier has splendid anticorrosion and impermeabilisation effect; can effectively avoid the corrosion of downhole corrosion gas and small-molecule substance to cable insulation; because fluoroplastics itself belong to insulating material, can further improve the electrical property of cable simultaneously.
Claims (2)
1. the circular submersible electric pump cable of two sheaths comprises conductor, insulating barrier, restrictive coating, armour, and conductor outer wrapping insulating barrier is characterized in that: extruding outside the insulating barrier (2) of described conductor (1) and being wrapped with restrictive coating (3) is the single line core; Three core triangularities are arranged the back by rubber sheath (4) coating, and rubber sheath (4) is outside equipped with armour (5).
2. according to the circular submersible electric pump cable of described pair of sheath of claim 1, it is characterized in that: the material of described restrictive coating (3) is fluoroplastics.
