Abstract

The invention belongs to the technical field of load-bearing detection cable, in particular to a low armored resistance bearing detection cable, which includes one or more sets of centrally located copper strands, the outer ring of the copper strand is covered with an insulating layer, The outer stranded ring of the insulating layer is sheathed with an inner steel wire armor layer, the inner steelwire armor layer is surrounded by a group of steel wires with circular cross-section and micro-steel pipe cables into a sealed circular ring, the inner steel wire armor layer is sheathed with an outer steel wire armor layer, and the outer steel wire armor layer is surrounded by a group of steel wires with fan-trapezoid cross-section into a sealed circular ring. The invention has the beneficial effects that the low armor resistance bearing detection cable of the invention is ingenious in structure design, smooth and wear-resistant in surface, and is suitable for popularizing and using.

Description

technical field [0001] The invention belongs to the technical field of load-bearing detection cables, in particular to a load-bearing detection cable with low armor resistance. 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. When the single-core cable is going downhole, because the armor layer is needed as a current loop, the problem of high resistance of the armor layer greatly hinders the instrument going into the well. Contents of the invention [0003] In order to solve the above problems and make up for the shortcomings of the traditional technolo...
