Description
Technical field
A kind of enhanced electric cable of submersible pump is the utility model is related to, suitable for the technical field of oil well engineering.
Background technology
Electric cable of submersible pump is mainly used in oil-immersed pump, and the working environment of oil-immersed pump is usually the underground activities in several kms.
Condition of work is severe in oil well, often in the very strong environment of the corrosivity such as high temperature, high pressure, and oily.Electric cable of submersible pump
Intensity, durability, the anti-corrosive properties needed are especially strong.Electric cable of submersible pump of the prior art faces following technical problem：
1st, intensity deficiency.Because the length of electric cable of submersible pump is longer, and certain load is born, therefore use process
In, the easy phenomenon being broken.Therefore, in the prior art typically by setting armor or coiled tubing in the outside of cable
To solve.
2nd, durability and anti-corrosive properties are poor.Conventional oil-immersed pump outermost layer sets common plastic sheath, and oil-immersed pump goes into the well one
As require continuous work really long days, the damage of cable can be found during maintenance every time, splitting used cable often can be with
It was found that sheath damage causes liquid to enter inside cable, in high temperature environments, it is swelled polypropylene insulation layer, after swelling
Insulating barrier softens, dielectric strength reduces, and causes copper cash core shift to cause local cable to puncture.
For example, Chinese patent application 201610312692.2 discloses a kind of electric cable of submersible pump for hanging installation, including
Multiple conducting wires, packed layer, restrictive coating, armor, each wire is by the conductor positioned at middle part, the insulating barrier being coated on outside conductor
With the wrapped oil resistant bed course composition outside insulating barrier；The multiple conducting wires twist together, and pass through filling between multiple conducting wires
Thing is filled, and filler cladding multiple conducting wires form packed layer, and restrictive coating is coated on the outside of packed layer, and armor is coated on
The outside of restrictive coating.
Chinese patent application 201521065012.9 discloses a kind of double armor electric cable of submersible pump, and copper conductor is surrounded by
One layer of close insulating barrier, one layer of close restrictive coating is surrounded by insulating barrier, it is resistance in one layer of the surrounding cladding of restrictive coating
Lubricating pad layer, the core of 3 this structures is then made into first layer steel-tape armouring side by side, made again in the outside of first layer steel-tape armouring
Make second layer steel-tape armouring.
Chinese patent application 201410098616.7 discloses a kind of circular submersible pump cable, including a supporting-core, more
Root wire, polytetrafluoroethylene (PTFE) lapping layer, anti-oil reservoir, restrictive coating and armor；Each wire include positioned at middle part conductor and
The insulating barrier being coated on outside conductor, polytetrafluoroethylene (PTFE) lapping layer is coated outside the cable core, outside polytetrafluoroethylene (PTFE) lapping layer
Portion coats anti-oil reservoir, and restrictive coating is coated outside anti-oil reservoir, armor is coated outside restrictive coating.
Above-mentioned three kinds of electric cable of submersible pump in outside by the way of armor is set, although disclosure satisfy that the need of intensity
Ask, but because armor is generally metal material, so easily corroded by underground corrosion medium especially hydrogen sulfide, and
Manufacturing cost is also add, use is also inconvenient.
Chinese patent 201210283869.2 discloses a kind of stranded conductor longitudinal direction pressure-resistant seal electric cable of submersible pump, including sets
The stranded conductor of center portion position in the cable is put, in addition to is wrapped in the insulating barrier outside stranded conductor, described stranded conductor bag
The center conductor and perimeter conductors twisted together is included, semi-conductive rubber is provided between described center conductor and perimeter conductors
Filling.The patent substituted for the ointment class filler in traditional cable using semi-conductive rubber, solve ointment at normal temperatures by
Solid-state is changed into the possibility of liquid.The deadweight of cable is required to be undertaken by conductor itself in the program, therefore its bearing capacity is very
It is limited, easily it is broken, the length of unit cable can not possibly be too big；Be additionally, since conductor outer wrap is commonly to insulate
Layer, its decay resistance is poor, and along with the needs of carrying, the thickness of required insulating barrier is very big, substantially cable radius
1/3rd.The insulating barrier of so big thickness make it that the effective working volume of cable is largely taken, and causes the waste of volume,
Therefore general applicability is not strong.
Therefore, need in the prior art it is a kind of can not only meet the requirement of large bearing capacity, but also disclosure satisfy that anti-corruption
The electric cable of submersible pump of corrosion requirement.
