Abstract
The utility model relates to a special power cable for high-intensity bearing oil well pumps, which mainly solves the problems of low bearing capability and poor corrosion-resistant performance of power cables in current oil well pumps. The utility model is characterized in that modified polypropylene insulating layers(2) are arranged on the outside of three cable cores(1) which are arrayed in a shape of a star and arranged in a half-shield covering tape(4) with circular cross section, non-metal material filling(5) is in the gap between the modified polypropylene insulating layers(2) and the half-shield covering tape(4), an armoured layer(6) is winded around the outside of the half-shield covering tape(4), and a sheath layer(3) is arranged on the outside of the armoured layer(6) and made of polymeric materials which can resist oil, abrasion, corrosion and low temperature. The utility model has the characteristics of high bearing capability, good corrosion-resistant performance and long service life.
Description
Technical field:
The utility model relates to the used a kind of private cable of oil well pump electric power transfer in the oil recovery field, oil field, especially high strength carrying oil well pump special electric power cable.
Background technology:
In oil recovery field, oil field, the lifting of crude oil is to realize that by the oil well pump that is installed in the down-hole supply of electric power of oil well pump is carried by three-core cable, and this three-core cable bearing capacity is low, is easy to be broken when underground work, causes damage to production.In oil recovery process, cable is in the extraction liquid, the corrosion-resistant of cable, contain former Oil, Water, Gas, acid, alkali, polymer etc. in the extraction liquid, these materials can wear out to the external insulation layer of cable, the armour corrosion, and the replacement cycle is shortened, and influence ordinary production.
The utility model content:
In order to overcome the low deficiency that reaches corrosion-resistant of existing oil well pump power cable bearing capacity, the utility model provides a kind of high strength carrying oil well pump special electric power cable, and this high strength carrying oil well pump special electric power cable has the characteristics of bearing capacity height, good corrosion resistance and long service life.
The technical solution of the utility model is: this high strength carrying oil well pump special electric power cable comprises cable core, cable core has the modified polypropene insulating barrier outward, cable core is 3 and is the arrangement of " star " shape, it is that circular half screen covers in the band that cable core places the cross section, insulating barrier and half screen cover in the space of band the nonmetallic materials obturator, half screen covers band and is wound with armour outward, and armour has the restrictive coating of oil resistant, wear-resisting, corrosion-resistant, low temperature resistant macromolecular material outward.
Above-mentioned cable core is a copper conductor material; Armour is positive and negative two-layer winding; Restrictive coating is the PVC material; Armour is a high carbon alloy high strength steel wire material.
The utlity model has following beneficial effect: owing to take such scheme, armour that bigger tensile strength is arranged, can not broken when underground work, the outer modified polypropene insulating barrier of cable core has corrosion resistance preferably, long service life.
Description of drawings:
Accompanying drawing 1 is a structure cross-sectional view of the present utility model.
1-cable core among the figure, the 2-insulating barrier, the 3-restrictive coating, the 4-half screen covers band, 5-obturator, 6-armour.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this high strength carrying oil well pump special electric power cable comprises cable core 1, and cable core 1 can effectively reduce the D.C. resistance of cable core 1 for copper conductor material is made, and reduces electric energy loss on the way, improves electrical efficiency.Modified polypropene insulating barrier 2 is arranged outside the cable core 1, can prevent the corrosion to insulating barrier 2 such as down-hole Oil, Water, Gas, acid, alkali, polymer, cable core 1 is 3 and is the arrangement of " star " shape, it is that circular half screen covers in the band 4 that cable core 1 places the cross section, insulating barrier 2 and half screen cover in the space of band 4 nonmetallic materials obturator 5, because obturator 5 is arranged, can guarantee the compact rounding of the construction of cable, half screen covers band 4 can effectively avoid armour 6 damage to insulating barrier 2 in cables manufacturing process and use.Half screen covers and is wound with positive and negative two-layer armour 6 outside the band 4, armour 6 adopts the high carbon alloy high-tensile steel wires to make, armour 6 is outer to be with the restrictive coating 3 of oil resistant, wear-resisting, corrosion-resistant, low temperature resistant macromolecular material, restrictive coating 3 is selected the PVC material for use, restrictive coating 3 can intercept down-hole Oil, Water, Gas, acid, alkali, polymer etc. and directly contact with armour 6, increases the useful life of cable.
During actual the use, because armour 6 has bigger tensile strength, can not broken when underground work, cable core 1 outer modified polypropene insulating barrier 2 has corrosion resistance preferably, long service life.Because restrictive coating 3 is a kind of macromolecular materials, its wear resistance is relatively poor, can grind leakage when frequently removing in oil pipe, does not generally add sheath 3 in experimental stage, installs restrictive coating 3 after downhole pump is working properly again additional.
