FUNCTIONCOMPOSITIONTECHNICAL SPECIFICATIONS
Flexible joint sub is
used in horizontal well logging and irregular well logging, making downhole
tools curve in any direction and move smoothly in the well to finish well
logging.
It is composed of
through line and housing. The circuit housing is made of PH stainless steel.
Temperature Range: -25 -175℃
Max. Pressure: 140MPa

Electric Connectivity Requirements: use
multimeter to calculate all 31 pin through line, the resistance value<0.4Ω Insulation resistance under NPT:
use 500VDC tramegger to check insulation resistance
between
pin and socket to housing, and it should be no less than200MΩ.
High-temperature
insulation resistance: heat up to175℃in the high-temperature
cabinet and keep inside for one hour. Use 500VDC
tramegger to check insulation resistance
between
pin and socket to housing, and it should be no less
than 100MΩ.
