Embodiment Construction

[0031] Accompanying drawing is a kind of specific embodiment of the present invention.

[0032] A WMF series sealed load-bearing detection cable, including a copper stranded wire 1, the outer layer of the copper stranded wire 1 is wrapped with an insulating layer 2, and the outer twisted ring of the insulating layer 2 is covered with an inner armor layer 3, and the inner armor layer The outer stranded ring of layer 3 is covered with an outer armor layer 5;

[0033] The inner armor layer 3 is composed of steel wires with a circular cross-section and a sealant layer 4. A plurality of circular steel wires are twisted and looped on the outside of the insulating layer 2, and the gaps between adjacent circular steel wires are covered with sealant. The layer 4 is poured and filled, and the sealant layer 4 and the circular steel wire together form a closed structure with a circular cross section;

[0034] The outer armor layer 5 is formed by twisted rings with circular and dumbbell-s...

Abstract

The invention relates to a WMF series sealed load-bearing detecting cable. The WMF series sealed load-bearing detecting cable comprises a copper stranded wire, the outer layer ring of the copper stranded wire is coated with an insulation layer, the outer ring of the insulation layer is sleeved with an inner armor layer, and the outer ring of the inner armor layer is sleeved with an outer armor layer; the inner armor layer is commonly formed by round steel wires and a sealant layer, the round steel wires sleeve the outer portion of the insulation layer, gaps between the adjacent round steel wires are filled with the sealant layer, the sealant layer and the round steel wires commonly form a sealed structure having a circular cross section; the outer armor layer is formed by sleeving steel wires having round and dumbbell-shaped cross sections, and after the steel wires having round and dumbbell-shaped cross sections are sleeved, the outer armor layer forms a sealed structure having a circular cross section. The cable designs novel inner and outer armor layer structures to improve the sealing and the reliability of the cable while improve the cable bearing.

Description

technical field [0001] The invention relates to the field of cables, in particular to a WMF series sealed load-bearing detection cable. Background technique [0002] With the rapid development of wireline logging technology and the advent of new logging instruments, the production technology of load-bearing detection cables used in conjunction with it is becoming more and more perfect. , Logging, perforating, coring and other operations of gas wells; it can also be used in marine surveys, rivers, harbors, water conservancy, hydrological surveys, coal field geological exploration, geothermal logging, etc. [0003] Among the above-mentioned cables, there are deep well cables, ultra-deep well cables and extra-ultra-deep well cables. The load-bearing capacity, anti-overflow performance, convenience of installation and use, and signal transmission capacity of the cable all play a decisive role in the quality of the cable. [0004] However, the inner and outer armor layers of tr...
