Abstract
The utility model relates to a hollow dermal-collecting electric heating oil pumping rod cable of an oil pumping machine. The hollow dermal-collecting electric heating oil pumping rod cable of an oil pumping machine is characterized in that the center of the hollow dermal-collecting electric heating oil pumping rod cable of an oil pumping machine is provided with a reinforcing core which is composed of a plurality of steel wires. A conducting wire layer which is composed of a plurality of copper wires is arranged outside the reinforcing core. An insulating layer is tightly coated outside the conducting wire layer. An outer armor steel wire protective layer which is composed of a plurality of steel wires is arranged outside the insulating layer. The hollow dermal-collecting electric heating oil pumping rod cable of an oil pumping machine has the advantages that the pull resistance and the abrasion resistance of the hollow dermal-collecting electric heating oil pumping rod cable of an oil pumping machine are enhanced, the working period of an electric heating rod and the service life of the hollow dermal-collecting electric heating oil pumping rod cable of an oil pumping machine can be extended, and an oil exploitation rate is enhanced.
Description
The utility model belongs to heating cable, the hollow collection skin of particularly a kind of oil pumper electric heating rod cable.
The hollow collection skin of present existing oil pumper electric heating rod adopts butyronitrile or rubber and plastic jacketed cable, utilizes kelvin effect, and crude oil in the well is heated dilution, has improved the high coefficient of mining that coagulates viscous crude.But it is generally all gradient that weak point is oil well, has multiple-tubing string to be connected, and butyronitrile or rubber and plastic sheath tension anti-wear performance are poor, very easily cause the damage to sheath, thereby influence the useful life and the oil producing operation of cable.Because the length of whole cable is all more than 1000 meters, the sheath deadweight is bigger, very easily causes the accumulation of sheath and insulation after being heated, and makes strain relief clamp in oil pipe, is difficult to propose or can not carry outside the well, influences normally carrying out of oil extraction operation.
The purpose of this utility model provides the hollow collection skin of a kind of oil pumper electric heating rod cable, overcomes above-mentioned shortcoming and defect, and pull resistance is provided, and eliminates the packing phenomenon of well inner sheath.
The purpose of this utility model is achieved in that
The hollow collection skin of a kind of oil pumper electric heating rod cable is characterized in that: the strengthening core that the center of cable is made up of the steel wire of multiply; strengthening core is outward the conductor layer that stranded copper wire is formed; outer hard-pressed bale one layer insulating of conductor layer, the outer steel wire protective layer that insulating barrier is made up of steel wire strand outward.
Strengthening core forms by the steel wire of multiply is stranded; Conductor layer is to form by stranded copper wire is stranded.
Between outer steel wire protective layer and the insulating barrier one deck bonding agent can be arranged.
The bed course that one deck glass tape coiled also can be arranged between outer steel wire protective layer and the insulating barrier.
The outer steel wire protective layer outward also can be all or is scribbled one deck bonding agent with interval.
More than the also available iron wire of the steel wire of Shi Yonging replaces.
The utility model has the advantages that: the pull resistance of cable and resistance to wear are strengthened, can prolong the work period of heating sucker rod and the useful life of cable, improve the oil exploitation rate.
Below in conjunction with description of drawings:
Fig. 1 is the hollow collection skin of an oil pumper electric heating rod cable schematic diagram
Fig. 2 is the hollow collection skin of an oil pumper electric heating rod cable cutaway view
Cable is that external diameter is the round cable of 16mm; the stranded strengthening core that forms 4 of steel wire that the center of cable is is 1.0mm by 7 strands of diameters; strengthening core be outward by 30 strands of diameters be the 1.03mm copper wire by with the concentric reverse conductor layer 3 that bilayer is stranded in the outer rim of strengthening core that is of strengthening core; conductor layer is outward that hard-pressed bale one layer thickness is the polypropylene insulating barrier 2 of 1.84mm, and insulating barrier is outward to be the outer armour iron wire protective layer 1 that single-layer stranding forms in the insulating barrier outer rim by 30 strands of diameters for the 1.20mm galvanized wire.
Between outer armour iron wire protective layer and the insulating barrier one deck bonding agent is arranged all.
Also can scribble one deck bonding agent with interval between outer armour iron wire protective layer and the insulating barrier.
The bed course that one deck glass tape coiled also can be arranged between outer armour iron wire protective layer and the insulating barrier.
Outer armour iron wire protective layer all scribbles one deck bonding agent outward.
Outer armour iron wire protective layer also can scribble one deck bonding agent outward with interval.
