Abstract

Installation de forage de puits avec un circuit de transmission de données. Le circuit de transmission comprend un générateur de mots de synchronisation disposé dans l'outil de forage, et qui délivre un signal numérique, un codeur de phase relié à un câble qui transmet les signaux codés à la surface. Un décodeur de phase redonne un signal numérique série, qui est converti en signal parallèle. Application aux installations de forage de terrains.
