Abstract
Provided is an electric submersible pump cable allowing wellhead drug adding. The object of the utility model is to overcome defects of field worker increase, work efficiency reduction, and unsafety factor increase in construction process caused by separation of a drug adding device, which is used for exploiting high toughening oil, high pour-point oil and high wax oil, in the prior art, and a electric submersible pump. The Electric submersible pump cable comprises conductors, insulation layers, oil resistant layers, a sheath layer and an armored layer, wherein each conductor is wrapped by an insulation layer and an oil resistant layer to form a wire core, and three wire cores are wrapped by the sheath layer to form a cable core; the cable core is arranged side by side with a drug adding pipe, and the cable core and the drug adding pipe are wrapped by the armored layer; if the cable core is a flat cable, the drug adding pipe and the cable core will be arranged in a linear manner, and if the cable core is a round cable, the drug adding pipe and the cable core will be arranged in a parallel manner. The electric submersible pump cable has beneficial effects of being simple in structure, being practical in function, being high in reliability, being capable of reducing field operators, and having a drug adding function for an oil well, as well as a function of supplying power for the electric submersible pump.
Description
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 submersible electric pump cable that can well head medicine-adding.
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 increasing of oil well produced liquid, increasing of water content, the scale problems on oil well and stratum is outstanding, when the crude oil of oil well is high viscosity heavy oil, high solidifying oil, high wax deposition oil, have a strong impact on the normal production of submersible electric pump, cause oil well output to reduce, production flow line or equipment stop up, pump detection period shortens, and oil recovery production cost increases.
At present, conventionally adopt in well and add the method for chemical agent to solve high viscosity heavy oil, high solidifying oil, the difficult problem of high wax deposition oil exploitation.The chemicals dosing plant of existing submersible electric pump abandoned wells is and the uncorrelated self-contained unit of submersible electric pump, in using at the scene, need to provide stand-alone service, causes field operation personnel to increase, and operating efficiency reduces, and the unsafe factor in construction operation process increases.
Utility model content
Separated with submersible electric pump in order to overcome in existing high viscosity heavy oil, high solidifying oil, the exploitation of high wax deposition oil chemicals dosing plant, field operation personnel are increased, operating efficiency reduces, the deficiency that in construction operation process, unsafe factor increases, the utility model provides a kind of submersible electric pump cable that can well head medicine-adding.
The utility model solves the technical scheme that its technical problem adopts: submersible electric pump cable that can well head medicine-adding, comprise conductor, insulating barrier, oil resistant layer, restrictive coating, armour, conductor is coated with insulating barrier outward successively, oil resistant layer is single line core, three cores are coated as cable core by restrictive coating, after cable core and chemical feed pipe are arranged side by side, with steel band, in its outside, are coated armour.When cable core is flat cable, chemical feed pipe and cable core word order are coated armour; When cable core is circle cable, chemical feed pipe and cable core be coated armour side by side.Chemical feed pipe is stainless steel metal tubing.
The beneficial effects of the utility model are, simple in structure, practical function, reliability be high, reduce site operation personnel, when providing electric power for submersible electric pump, has the function of oil well dosing.

Fig. 1 is the flat cable structural representation of the submersible electric pump cable that the utility model can well head medicine-adding.
Fig. 2 is the round construction of cable schematic diagram of the submersible electric pump cable that the utility model can well head medicine-adding.
In figure: 1. cable core, 2. chemical feed pipe, 3. armour, 4. sheath, 5. core.
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 invention is not restricted to listed embodiment, as long as spirit according to the invention all should be included in protection scope of the present invention.
Referring to accompanying drawing.The utility model can well head medicine-adding submersible electric pump cable, comprise conductor, insulating barrier, oil resistant layer, restrictive coating, armour, conductor is coated with insulating barrier outward successively, oil resistant layer is single line core 5, three cores 5 are coated as cable core 1 by restrictive coating 4, after cable core 1 is arranged side by side with chemical feed pipe 2, with steel band, in its outside, are coated armour 3.Chemical feed pipe 2 is selected stainless steel metal tubing conventionally.
When cable core 1 is flat cable, chemical feed pipe 2 is coated armour 3(referring to accompanying drawing 1 with cable core 1 word order).When cable core 1 is circle cable, chemical feed pipe 2 is coated armour 3(referring to accompanying drawing 2 side by side with cable core 1).
The utility model can well head medicine-adding submersible electric pump cable both can provide electric energy for Electric Submersible Pump Unit, can to assigned address in oil well, inject chemical agent by chemical feed pipe again, can reduce operating personnel, increase work efficiency, increase the fail safe in construction operation process.
It should be noted that above-described embodiment is example and unrestricted the utility model, those skilled in the art can design a lot of alternate embodiments and not depart from the claim scope of this patent.
