Abstract

L'invention concerne un procédé amélioré d'installation d'une conduite d'écoulement sous une surface qui comprend les étapes consistant à établir un premier et un deuxième trou de dégagement de visualisation le long d'une voie linéaire; à positionner une machine de forage dirigé sur la surface; à forer une première partie d'un trou pilote à partir de la surface jusqu'au premier trou de dégagement de visualisation; à déterminer l'élévation d'un outil de forage et à ajuster celui-ci à la profondeur désirée; à forer une deuxième partie du trou pilote jusqu'au deuxième trou de dégagement; et à déterminer l'élévation de l'outil de forage et à ajuster celui-ci à la profondeur désirée. Selon un autre aspect, l'invention concerne un procédé de forage dirigé d'une conduite d'écoulement qui comprend les étapes consistant à établir un certain nombre de trous de dégagement de visualisation le long de la voie désirée du forage; à forer de manière dirigée un trou pilote; à aléser le matériau autour du trou pilote de façon à définir un forage au moins partiellement rempli d'une boue de forage du matériau alésé; et à tirer un conduit dans le forage dans lequel une partie de la boue de forage est déplacée dans les trous de dégagement de visualisation de sorte qu'il n'y ait pas de pression autour du conduit.
