FIELD: oil production technologies; manufacturing a sealed fibre optic channel cable for logging.
SUBSTANCE: manufacturing method includes four steps: forming an optical fibre protective tube in which the optical fibre is situated; forming a filling layer formed with an aluminium tube, forming a reinforcing tube, and forming a sealing layer.
EFFECT: invention makes it possible to manufacture a long fibre optic channel cable with high strength, good thermal stability, low signal transmission losses, high transmission speed and synchronous transmission of multiple signals.
