CA 2411411
A well logging apparatus is provided having downhole well data acquired by a sensor, transmitted to the surface via complementary moderns, and conveyed to the surface modem via a data transmission cable linking the modems, the cable having at least one pair of insulated conductors wound in a substantially helical twist, an insulation sheath surrounding the twisted pair of conductors and a tensile load carrier surrounding the insulation sheath, the load carrier comprising a sheath of tensile load carrying filaments.
L'invention concerne un appareil de diagraphie de sondage dans lequel des données de forage sont acquises par un capteur, transmises à la surface par l'intermédiaire de modems complémentaires et acheminées au modem de surface par l'intermédiaire d'un câble de transmission de données reliant les modems. Ce câble comporte au moins une paire de conducteurs isolés enroulés en torsade sensiblement hélicoïdale, une gaine isolante entourant la paire torsadée de conducteurs et un porteur de charge de traction entourant la gaine isolante, ce porteur de charge comprenant une gaine de filaments porteurs de charge de traction.
