Title
(EN) DEVICE FOR MEASURING DRILLING MAST SWIVEL MOVEMENT
(FR) DISPOSITIF DE MESURE DU DEPLACEMENT D'UNE TETE D'INJECTION D'UN MAT DE FORAGE
Abstract
(EN)
A device for measuring the movement of a drill pipe string, the end of which is held during drilling by an attachment assembly (12) movably along at least one guide rail (16), comprises a sensor assembly (38) mounted on the attachment assembly with a roller (42) designed to run on the rail as the attachment assembly moves.
(FR)
Dispositif de mesure du déplacement d'un train de tiges de forage, dont l'extrémité est soutenue lors du forage par un ensemble d'accrochage (12), déplaçable le long d'au moins un rail de guidage (16), le dispositif de mesure comprenant un ensemble capteur (38) monté sur l'ensemble d'accrochage et comportant un galet (42) adapté à rouler sur le rail lors du déplacement de l'ensemble d'accrochage.
