The invention relates to the technical field of load bearing detection cables, and discloses an all-phase demodulation distributed optical fiber sensing load bearing detection cable which comprises an outer steel wire armor layer. According to the all-phase demodulation distributed optical fiber sensing load bearing detection cable, the outer steel wire armor layer is installed on the outer side of an anti-corrosion layer, an inner steel wire armoring layer is installed on the inner side of the anti-corrosion layer, one third of the inner wall of the outer steel wire armor layer is embedded into the anti-corrosion layer, the outer steel wire armoring layer is limited, and the appearance of the cable is stable; the outer steel wire armor layer is formed by winding four complete steel wires on the surface of the anti-corrosion layer, and the winding mode enables the outer steel wire armor layer to be more stable; in addition, the resistant steel wire is installed in the center of the cable, the cable can be effectively prevented from being stretched or even snapped, the purpose of preventing the wire from shrinking is achieved. And the source of the whole cable is fastened through a fastening ring at the source, so that the inner core of the cable cannot slip off in the stretching and extending process.
Description
technical field [0001] The invention relates to the technical field of load-bearing detection cables, in particular to an all-phase demodulation distributed optical fiber sensing load-bearing detection cable. Background technique [0002] Load-bearing detection cables are suitable for oil mine detection cables that bear mechanical loads for electrical measurement. This type of cable is used for well logging, perforation, coring and other operations of various oil and gas wells; it can also be used for marine surveys, rivers, harbors, water conservancy, etc. , hydrological survey, coal field geological exploration, geothermal logging, etc., as the connection line for the measurement of the heavy-duty instrument, the existing load-bearing detection cable is used for a long time, and the long-distance construction and stretching, the internal wire is prone to shrinkage, resulting in The wire is retracted into the armor layer, and when the load-bearing detection cable is subject...
