Title
(EN) STEERING HEAD WITH INTEGRATED DRILLING DYNAMICS CONTROL
(FR) TÊTE DE DIRECTION DOTÉE D'UNE COMMANDE INTÉGRÉE DE DYNAMIQUE DE FORAGE
Abstract
(EN) A method, apparatus and computer-readable medium for reducing a vibration of a drill string in a borehole. A sensor of the drill string obtains one or more measurements of a parameter of the vibration. A processor determines at least one force for controlling the measured vibration from the measured parameter. At least one actuator applies the determined at least one force against the borehole wall to control the vibration of the drill string.
(FR) La présente invention concerne un procédé, un appareil et un support lisible par ordinateur permettant de réduire une vibration d'un train de tiges de forage dans un trou de forage. Un détecteur du train de tiges de forage obtient une ou plusieurs mesures d'un paramètre de la vibration. Un processeur détermine au moins une force permettant de commander la vibration mesurée à partir du paramètre mesuré. Au moins un actionneur applique la ou les forces déterminées contre le mur du trou de forage pour commander la vibration du train de tiges de forage.
