Further, the copper stranded wires are copper wires, tinned copper wires or silver-plated copper wires.
The skeleton is PE material, guarantees that the cable still can resume the original state after crooked, improves cable stability, reliability.
The reinforcing pipe is made of carbon fiber, is light in weight, high in strength, good in fatigue resistance and corrosion-resistant, and increases the bearing capacity of the cable.
The composite material armor layer is a core rod armor formed by compounding resin with the temperature resistance of more than 250 ℃ and fiber with the strength grade of more than 2000MPa, so that the breaking force and corrosion resistance of the cable are improved.
The outer armor layer is formed by armor with special-shaped steel wires, wherein the cross section of the special-shaped steel wires is in a sector ring shape, Z-shaped shape or can be combined into a circular ring shape, and the outer surface of the special-shaped steel wires is in a pure circle shape.
Waterproof sealant is filled between the inner armor layer and the composite material armor layer and between the composite material armor layer and the outer armor layer, so that no gap exists between layers of the cable, the inside of the cable is prevented from being corroded and polluted, and underground high-pressure fluid can be prevented from overflowing to the well surface along the cable gaps.
The beneficial effects of the invention are as follows: the invention relates to a load-bearing test photoelectric composite strong cable special for sealing bailing, which is mainly used for a low-yield liquid bailing well in the later period of oilfield development, and has the functions of permanent online measurement of the distributed temperature and pressure of a whole well, paraffin removal, blocking removal and the like of a shaft besides being used as a load-bearing dynamic sealing connection of a flexible reciprocating bailing cylinder for long-term use instead of an original steel wire rope.
