Abstract

The composite load-bearing detection cable of the invention is characterized in that the composite load-bearing detection cable comprises a plurality of single-core cables twisted together, and the outer ring of the single-core cables is twisted with an inner steel wire armored layer. The inner steel wire armor layer is surrounded by a group of steel wires with circular cross-section and hollow steel tubes arranged in a sealed circular ring, the outer stranded ring of 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 steel wires with fan-shaped cross-section to form a sealed circular ring. The invention has the advantages of simple structure, convenient use, durability, good flexibility, portability, reasonable structure design, smooth surface and wear resistance, and is suitable for popularization and use. The central steel pipe and the steel pipe distributed in the inner armor layer of the invention play the roles of chemical reagent injection, cable cooling and optical fiber layout. The steel wires forming the outer steel wire armor layer are fan-trapezoidal, which greatly reduces the gap between the armor wires.

Description

technical field [0001] The invention relates to the field of load-bearing detection cables, in particular to a composite type 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. The cable only plays the role of transmitting signals in the logging process, and cannot achieve the purpose of diversification of functions, which limits the use of load-bearing detection cables. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a composite load-bearing detection cab...
