Title (EN) METHOD OF DISCONNECTING A DRILL STRING AT A DRILL RIG
(FR) PROCÉDÉ DE SÉPARATION DE TRAIN DE TIGES SUR UN APPAREIL DE FORAGE
Abstract: front page image
(EN)Method and apparatus for disconnecting an end rod (115) from a drill string (100) coupled together by a threaded connection (604, 605). Rod handling apparatus (102) comprises a gripper unit (106) having a 'floating'sled (206) with a sensor unit (208) configured to monitor relative axial position of the sled relative to a frame (205) of the gripper unit to determine a decoupling of the threaded connection and a separation of an end rod from the drill string.
(FR)L'invention concerne un procédé et un appareil pour séparer une tige d'extrémité d'un train de tiges couplés ensemble par un raccord fileté. Un appareil de manipulation de tige comprend une unité de préhension comprenant un traineau flottant doté d'une unité de capteur conçue pour surveiller la position axiale relative du traineau par rapport à un cadre d'unité de préhension afin de déterminer le découplage du raccord fileté et la séparation de l'extrémité de tige du train de tiges.
