[0002] In the oil exploration, production logging, water well testing and adjustment, pumping and perforating industries, load detection cables are key equipment that undertake the important task of transmitting power, signals and data. However, in actual application, due to the complex and changeable working environment, load detection cables often face various challenges, among which the wellhead overflow problem is particularly prominent.

[0003] The prior art discloses a closed anti-overflow load detection cable with a publication number of CN104681166B, comprising a copper stranded wire, the outer ring of the copper stranded wire is provided with an insulating layer, the outer ring of the insulating layer is provided with an inner armor layer, the outer ring of the inner armor layer is provided with an outer armor layer; the inner armor layer is composed of a steel wire with a circular cross section and a sealant layer, a plurality of circular steel wires are provided on the outside of the insulating layer, the gaps between adjacent circular steel wires are filled with the sealant layer, and the sealant layer and the circular steel wire together form a closed structure with a circular cross section; the outer armor layer is provided with a steel wire ring with a fan-shaped cross section, and the outer armor layer also forms a closed structure with a circular cross section after the plurality of fan-shaped steel wires are provided. The cable provided in the present application improves the sealing and reliability of the cable while improving the carrying capacity of the cable by designing a new inner and outer armor layer structure.

[0004] The above-mentioned closed load-bearing detection cable adopts fan-shaped steel wire through the outer armor layer, which greatly reduces the gap between the armored steel wires. Sealant is coated between the inner and outer armor layers to form a closed structure for the inner and outer armor layers. However, the cross-section of the steel wire in the outer armor layer of the above-mentioned detection cable is not a special shape, and the cross-sectional area is also small. The strength and anti-buffering ability of the outer armor layer are weak, and it is easy to be damaged and affect normal use. The effect during use is not good, and this needs to be improved.
