Abstract

Description d'un système de télémesure en temps réel à utiliser avec un système de forage et qui comporte un robinet rotatif 28 régulant l'alimentation en fluide ou boue de forage à un outil de fond de puits. Le système consiste à recevoir les données à transmettre, à encoder les données sous forme d'une durée et à commander la rotation du robinet rotatif 28 de manière que ce dernier tourne durant ladite durée à une vitesse de rotation prédéterminée pour causer la formation de fluctuations de pression ou de vagues dans le fluide ou la boue de forage.
