Title (EN) A ROTARY STEERABLE DRILLING ASSEMBLY WITH A ROTATING STEERING DEVICE FOR DRILLING DEVIATED WELLBORES
(FR) ENSEMBLE DE FORAGE ORIENTABLE ROTATIF DOTÉ D’UN DISPOSITIF D’ORIENTATION ROTATIF DESTINÉ AU FORAGE DE PUITS DÉVIÉS
Abstract:
(EN) A drilling assembly for drilling deviated wellbores is disclosed that in one embodiment includes a steering unit having an upper section coupled to a lower section through a tilt device, wherein an electro-mechanical actuation device tilts the tilt device about a selected location in the drilling assembly to cause the lower section to tilt relative to the upper section along a selected direction while the drill string is rotating.
(FR) L'invention concerne un ensemble de forage destiné au forage de puits déviés qui, dans un mode de réalisation, comprend une unité d’orientation ayant une section supérieure accouplée à une section inférieure par l'intermédiaire d'un dispositif d'inclinaison, un dispositif d'actionnement électromécanique inclinant le dispositif d'inclinaison autour d'un emplacement sélectionné dans l'ensemble de forage pour amener la section inférieure à s'incliner par rapport à la section supérieure le long d'une direction sélectionnée pendant la rotation du train de tiges.
