  • This invention relates to electrical cable, and particularly to electrical cable utilized to deliver electrical energy to submersible motors adapted for use in high temperature, high pressure oil wells.
  • Submersible pumps used in oil, mineral and water wells normally include a prime mover in the form of an electric motor directly coupled to the pump and disposed deep within the well. It is necessary to provide an electrical connection between the motor and a source of electrical energy at the surface as by the use of an electrical conducting cable which extends between the source of electrical energy and the motor.
  • the motors operate at relatively high power levels, in some case exceeding 200 horsepower.
  • the motors used are of the threephase type and the associated cable includes three separate electrical conductors.
  • the electrical cable must have adequate current carrying capability and must be of sufficient dielectric strength to prevent electrical losses even under the adverse environmental conditions usually found within the well.
  • the environmental conditions of the well vary generally depending upon geographical location. In some cases the well fluid is highly corrosive and in many instances well temperatures exceed 275F. Most oil well fluids include brines containing dissolved H S gas, carbonates and salts, and large volumes of oil.
  • the fluid pressure in wells may be quite high and in many instances exceeds 4,000 psig. Additionally, the wells are quite deep, averaging 8,000 to 10,000 feet.
  • the electrical cable must possess sufficient physical strength to allow insertion of the motor and cable to these depths and the outer'surface of the cable must resist the abrasion associated with insertion. Since the cable is normally wound upon storage or transportion reels, it must possess the additional property of flexibility, so that it will resist physical damage caused by reelmg. I
  • Typical cable construction presently being utilized includes three conductors of copper separately insulated are helically wound to form a single unit.
  • the conductors are insulated with a material of high dielectric strength such as polyethylene or polypropylene.
  • the helically wound and insulated conductors are sheathed in an extruded jacket of nitrile rubber surrounding the insulated conductors.
  • jacketed cable is covered with an outer armor in the form of a continuous wrapped band of metallic material. This band is lapped as it is wound.
  • the armor provides abrasion resistance.
  • the armor is formed of steel or bronze; however, in many special applications, such as wells which are excessively corrosive, stainless steel or exotic metals such as monel metal must be used.
  • Polyethylene has also been employed to a limited extent as the outer armor, but it has been found that the same does not stand up under severely high temperatures.
  • Rupture of the armor due to swell of the jacket is another example of deformation which occurs in such an environment.
  • Rupture of the total construction also occurs during retraction of the cable from the well as a result of the depressurization of fluids which have permeated the cable.
  • the present invention relates to an improved multicomponent electrical cable for submersible motors adapted for use in high temperature, high pressure oil wells.
  • a cable constructed according to this invention comprises an outer armor of metal, an inner jacket of epichlorohydrin rubber, and high temperature, synthetic, organic insulators surrounding the electrical conductors.
  • the insulators are useful in high temperature, high presure oil wells.
  • One of these insulators is a high temperature, high molecular weight, extrudable thermoplastic fluorocarbon polymer, which is an excellent electrical insulator at elevated temperatures when unaffected by oil and brine. While the thermoplastic fluorocarbon is suitable for use in high temperature and pressure oil wells, it is very expensive and, accordingly, a very thin insulation layer is employed.
  • thermosetting elastomer rubber such as ethylene-propylene copolymers and terpolymers, having the required heat resistance and electrical properties necessary for use as commercially manufactured oil well cable insulation.
  • the epichlorohydrin rubber used for the jacket is compounded for the minimum of oil and water permeability and swell.
  • the epichlorohydrin rubber jacket is oil and water insensitive and impermeable providing a barrier which protects the insulators from any loss of dielectric strength and electrical protection to the conductors. Furthermore, the insulators, being temperature insensitive, will not deform and change electrical insulation thickness.
  • the impermeability of the jacketing further insures that there be no permeating fluids to plasticize or soften the insulators and thus reduce their insensitivity to temperature deformation.
  • FIGS. 1 and 2 of the drawings there is shown a multi-component electrical conducting cable for a submersible motor designed for use in high temperature, high pressure oil wells which is illustrative of the principles of the present invention.
  • FIG. 1 shows a cable section which includes conductors 11, a resilient jacket 13 and an outer armor 15.
  • Each conductor 11 is illustrated as being formed of stranded wire 17 helically wound to prevent separation of strands. These separate strands may be tinned to minimize chemical interaction between the conductor and the insulating material. Solid conductors may be used without departing from the spirit of the invention.
  • each conductor includes seven strands.
  • the number of conductors, the diameter of the conductor and number of wires is, of course, dependent upon the load carrying capabilities required for a particular cable application. It should additionally be noted that any suitable conducting material may be used, such as, for example, copper, alumi num.
  • Each woundset of wire strands forms a single conductor and is separately insulated by an insulation layer 19.
  • the conductor insulation 19 is formed of a high temperature, organic, synthetic material of high dielectricstrength. High temperature, high molecular weight, extrudable fluorocarbon polymers have been found to be satisfactory for this purpose.
  • the thickness of the layer 19 may have a different relationship to the dimensions of the other elements of the cable than what is inferred by the drawing. However, the drawing illustrates the various elements which make up the cable without reference to actual dimensions.
  • a preferred embodiment of a high temperature, high molecular weight, extrudable fluorocarbon polymer is a 1:1 copolymer of ethylene and chlorotrifluoroethylene insulating material, commercially available under the trade name HALAR from Allied'Chemical Co. This material has a formula (CH Cl-l CF CFCl),
  • the extrudable ethylenechlorotrifluoroethylene copolymer is particularly suited for use in cable constructions intended for applications to oil well environments. Despite the fact of being a thermoplastic and therefore capable of melting and flowing under high temperature and pressures, it retains physical strength at elevated temperatures and dielectric strength at temperatures as high at 410F.
  • the resistance of the ethylene-chlorotrifluoroethylene copolymer to high temperature and high pressure fluid environments can also be improved by irradiation and by sheathing in an oil-and-brine resistant jacket.
  • the comparative properties of irradiated and unirradiated films of the ethylene-chlorotrifluoroethylene copolymer are:
  • compositions as DuPonts commercial PFA polymers Teflon 9704 and Teflon 9705, the known FEP polymeric materials, and the commercially available FEP/PE copolymers, such as Duponts Tefzel products and other extrudable fluorocarbon polymers and copolymers which possess the necessary extrusion characteristics are considered to be equivalent materials for this particular purpose, and therefore within the scope of the present invention.
  • thermoplastics are exceptionally qualified for oil well cables in view of their extrudability and resistance to a very high temperature and high pressure fluid environment, they are very expensive and, accordingly, in use must be necessarily restricted to a required minimum quantity to provide economical manufacture of the cables. Therefore, a further protective layer is necessarily present.
  • a layer of an insulating material having the needed heat resistant and electrical properties such as ethylene propylene copolymers and terpolymers, which is suitable for oil well cable insulation is employed to cover the thermoplastic insulation layer 19 as the conductor insulation 21.
  • An example of a suitable class of such an insulating material is heat-stablized ethylene-propylene copolymer rubber, including ethylene-propylene terpolymer rubber.
  • ethylene-propylene copolymer rubber including ethylene-propylene terpolymer rubber.
  • One example of such materials is found described in US. Pat. No. 2,933,480.
  • the flexible jacketing material resist oil and brine under the bottom hole conditions and that the wire insulation be protected to avoid permeation of gases and fluids which would cause rupture on depressurization and to avoid permeation by oil to plasticize or by water to reduce electrical resistance.
  • the wound conductor unit is thus disposed within the jacket 13 which is comprised of a high molecular weight epichlorohydrin rubber compounded for the minimum of oil and water permeability and swell.
  • This jacket may be extruded about the wound conductors and preferably is formed to fill interstices 23 between adjacent conductors.
