Accompanying drawing explanation
Fig. 1 is the sectional view of seven core high strength charge bearing detecting cables of the present utility model.
Embodiment
As shown in Figure 1, seven core high strength charge bearing detecting cables of the present utility model, comprise 7 fibre cores 1, fibre core 1 includes conductor, the outside of conductor is disposed with insulating barrier 11 and semiconductor sub-shield 12, filling semiconductor material 2 between fibre core 1, the outside of fibre core 1 is disposed with the total screen 3 of semiconductor, steel wire of internal layer armour 4 and cover wire armour 5.
Fibre core 1 is closed by multiply soft copper skein silk and forms.Power and transfer of data for downhole instrument.When 20 DEG C, conductor DC resistance is not more than 33 Ω/km.
Semiconductor sub-shield 12 is semiconductor electromagnetism glue-line.Eliminate the interference of electromagnetic field between core, ensure the efficiency of Signal transmissions.
The total screen 3 of semiconductor is semiconductor nylon tape.Duplication is greater than 50%.Total screen can strengthen the anti-external electromagnetic field jamming performance of entirety of cable, and make Signal transmissions more stable, data acquisition yield reaches more than 99.95%.
Steel wire of internal layer armour and cover wire armour are zinc-coated wire layer.By adjusting the setting of heat treatment process temperature and speed, change Steel Wire Drawing Process flow process, the compression ratio in steel wire drawing process between each mould, makes the intensity index of steel wire bring up to more than 2200Mpa from 1870MPa.Inside and outside two-layer high-strength galvanized steel wire makees the protection armor of cable core, will carry the mechanical load of high strength simultaneously, and meet the measurement operation of more than 7000 meters ultradeep wells, cable rupture pull force brings up to more than 110kN from the 85kN of routine.
