Abstract
A high-temperature-resistant submersible pump cable is provided to overcome the defect that cables in the prior art are not applicable to oil production of high-temperature oil wells. The cable comprises conductors, insulating layers, backing layers, sheath layers and an armor layer. Each conductor is coated by one of the insulating layers, one of the backing layers and one of the sheath layers successively from inside to outside to form a core; three cores are wrapped in the armor layer; and the sheath layers are thin-wall steel pipes. The beneficial effects are that the structure is simple, functions are practical, the reliability is high, and the cable satisfies the needs of high-temperature oil wells.
Description
Technical field
The utility model relates to a kind of submersible electric pump cable, especially relates to a kind of high temperature resistant submersible pump cable.
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 lower end is connected with jump lead, and upper end is connected with ground control cubicle, is laid in oil well.Along with the change of well recovery mode, the temperature at unit place can reach 260 DEG C, and existing cable cannot meet the oil recovery demand of high temperature resistant 260 DEG C.
Utility model content
The deficiency that can not adapt to high-temperature oil well oil recovery production existing in order to overcome existing cable, the utility model provides a kind of high temperature resistant submersible pump cable.
The utility model solves the technical scheme that its technical problem adopts: high temperature resistant submersible pump cable comprises conductor, insulating barrier, restrictive coating, armour, conductor outer wrapping insulating barrier, the insulating barrier of conductor is enclosed with laying outward successively, restrictive coating is single line core; Three cores are wrapped with armour, and restrictive coating is thin-wall steel tube.
The beneficial effects of the utility model are, simple in structure, practical function, reliability be high, meet the demand of high-temperature oil well to cable.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model high temperature resistant submersible pump cable.
In figure: 1. conductor, 2. insulating barrier, 3. laying, 4. restrictive coating, 5. armour.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.But those skilled in the art should know, the utility model patent is not limited to listed embodiment, as long as spirit according to the invention all should be included in the protection range of the utility model patent.
Referring to accompanying drawing 1.The utility model high temperature resistant submersible pump cable, comprises conductor 1, insulating barrier 2, laying 3, restrictive coating 4, armour 5, and conductor 1 is outer, and to be enclosed with successively insulating barrier 2, laying 3, restrictive coating 4 be single line core; Three cores are wrapped with armour 5 and form high temperature-resistant cable.Restrictive coating 4 adopts thin-wall steel tube, improve high temperature resistant, the high pressure resistant oil gas of cable and resistance toly collide with, performance and the compactness thereof such as resistance to compression.
The utility model high temperature resistant submersible pump cable, after the wrapped sintering supplementary insulation of conductor 1, extrude insulating barrier 2, carry out the coiling of laying 3 in insulating barrier 2 outsides, outside laying 3, complete the processing of thin-wall steel tube sheath 4, completed the making of a cable core.Then three cores are completed on armoring machine to the processing and fabricating of armour 5.Adopt thin-wall steel tube sheath can greatly improve high temperature resistant, the high pressure resistant oil gas performance of cable, improve performance and the compactness thereof such as it resistance toly collides with, resistance to compression, improve cable useful life and the adaptive capacity to subsurface environment.
It should be noted that above-described embodiment is example and unrestricted the utility model patent, those skilled in the art can design a lot of alternate embodiments and not depart from the claim scope of this patent.
