Abstract
The utility model provides an anti-collision submersible pump cable aiming at overcoming the defects that as the existing submersible pump cable adopts a single-layer sheath for protection, a metal lead sheath layer can be cracked by slight collision, an insulating layer is exposed in the severe environment in a well and is quick to age and fail, the cable has short service life and the oil extraction production cost can be increased. In the anti-collision submersible pump cable, the insulating layer (2) of a conductor (1) is externally wrapped with a metal sheath (3), a rubber sheath (4) and an oil-resisting pad layer (5) in sequence so as to form a wire core; and three wire cores are externally wrapped by an internal sheath layer (6) and an external sheath layer (7) in sequence from inside to outside. The anti-collision submersible pump cable has the benefits that a dual-layer steel strip is used for sheath so that the anti-collision performance of the cable can be improved greatly; the insulating layer is protected in a multiple way; and the anti-collision submersible pump cable has the characteristics of simple structure, high reliability and long service, and being functional and practical, and effectively reduces the oil extraction production cost.
Description
Affiliated technical field
The utility model relates to a kind of petroleum recovering machinery equipment oil-immersed pump unit cable, especially relates to a kind of anti-submersible electric pump cable that collides with.
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, can be under down-hole high temperature and pressure long-term operate as normal; Higher mechanical strength is arranged, in case in the process of removing, damage.
At present, submersible electric pump cable has two kinds of round cable and flat cables, no matter be circle cable or flat cable, all form by 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; The arranged outside of conductor has 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.
Along with the continuous progress of oil exploitation technology, the extensive use of directional well, inclined shaft, horizontal well, the probability that submersible electric pump cable collides with in the process in operation, weares and teares significantly improves.Existing submersible electric pump cable only adopts the individual layer armouring to protect, the armour mechanical strength is low, insulating barrier often is subjected to major injury owing to collide with, even slightly collide with metallic lead is ftractureed, make insulating layer exposing in the adverse circumstances of down-hole and quick aging, inefficacy, shorten the useful life of cable greatly, increase the oil recovery production cost.
The utility model content
Adopt the individual layer armouring to protect in order to overcome existing submersible electric pump cable, slightly collide with and to make metallic lead armour cracking, insulating layer exposing is in the adverse circumstances of down-hole and quick aging, inefficacy, cable is short useful life, increase the deficiency of oil recovery production cost, the utility model provides a kind of anti-submersible electric pump cable that collides with.
The technical scheme that its technical problem that solves the utility model adopts is: it is the single line core that the insulating barrier of the anti-submersible electric pump cable conductor that collides with is coated with metallic sheath, rubber sheath, oil resistant bed course outward successively; Three cores coat inner armor layer, armoured layer outward from the inside to the outside; Metallic sheath is a lead sheath; The fluorine plastic film of oil resistant bed course for twining.
The beneficial effects of the utility model are, adopt the clad steel band to carry out armouring, promoted the anti-performance of colliding with of cable greatly, and insulating barrier is subjected to multiple-protection, have characteristics simple in structure, that function is practical, reliability is high, the life-span is long, effectively reduce the oil recovery production cost.
Description of drawings
Fig. 1 is the anti-submersible electric pump cable structural representation that collides with of the utility model.
Among the figure: 1. conductor, 2. insulating barrier, 3. metallic sheath, 4. rubber sheath, 5. oil resistant bed course, 6. inner armor layer, 7. armoured layer.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to accompanying drawing 1.The anti-submersible electric pump cable that collides with of the utility model comprises conductor 1, insulating barrier 2, restrictive coating, armour, conductor 1 outsourcing insulating layer coating 2, and the insulating barrier 2 of conductor 1 is outer to be coated with metallic sheath 3, rubber sheath 4, oil resistant bed course 5 successively and to be the single line core; Three cores coat inner armor layer 6, armoured layer 7 outward from the inside to the outside; Metal sheath layer 3 wherein is a lead sheath; The fluorine plastic film of oil resistant bed course 5 for twining.Three cores in the inner armor layer 6 discharging side by side are flat cable.
The anti-submersible electric pump cable extruded rubber insulating barrier 2 behind conductor 1 surface coating that collides with of the utility model, carrying out lead system metallic sheath 3 in rubber insulation 2 outsides extrudes, metallic sheath 3 skins carry out extruding formation rubber sheath 4 with elastomeric material after the surface treatment, the rubber sheath 4 outer fluorine plastic films that twine are as oil resistant bed course 5, promptly finished the making of a cable core, then three cores have been finished successively the processing and fabricating of inner armor layer 6, armoured layer 7 on armoring machine.Adopt rubber sheath to extrude, can effectively protect lead sheath; Double armor can greatly promote cable machinery intensity, promotes the anti-ability of colliding with of cable greatly, effectively prolongs the useful life of cable.
The anti-submersible electric pump cable that collides with of the utility model protects at the outer rubber sheath that adopts of lead sheath, adopt the clad steel band to carry out armouring, promoted the anti-performance of colliding with of cable greatly, and insulating barrier is subjected to multiple-protection, have characteristics simple in structure, that function is practical, reliability is high, the life-span is long, effectively reduce the oil recovery production cost.
