Abstract

The invention relates to an anti-overflow sealed bearing loading and detecting cable which comprises a copper stranded wire, wherein the outer layer of the copper stranded wire is annularly sleeved by an insulating layer, the insulating layer is annularly sleeved by an inner armor layer, and the inner armor layer is annularly sleeved by an outer armor layer; the inner armor layer is composed of steel wires with a circular section and sealant layers, and the outer part of the insulating layer is annularly sleeved by a plurality of circular steel wires; gaps between the adjacent circular steel wires are filled with the sealant layers, and the sealant layers and the circular steel wires constitute the sealed structure with the circular section together; the outer armor layer is formed by annularly sleeving the steel wires with a fan-shaped section, and the outer armor layer also forms a sealed structure with a circular section after a plurality of fan-shaped steel wires are annularly sleeved. The cable provided by the invention has the novel inner and outer armor layer structures, so that the bearing capacity of the cable is improved, while the sealing performance and the reliability of the cable are improved.

Description

technical field [0001] The invention relates to the field of cables, in particular to an anti-overflow airtight 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...
