Title (EN) DRILL BITS, ROTATABLE CUTTING STRUCTURES, CUTTING STRUCTURES HAVING ADJUSTABLE ROTATIONAL RESISTANCE, AND RELATED METHODS
(FR) TRÉPANS, STRUCTURES DE COUPE ROTATIVES, STRUCTURES DE COUPE AYANT UNE RÉSISTANCE À LA ROTATION RÉGLABLE ET PROCÉDÉS S'Y RAPPORTANT
Abstract:
(EN) An earth-boring tool may include a body and at least one rotatable cutting structure assembly. The rotatable cutting structure assembly may include a leg, a rotatable cutting structure rotatably coupled to the leg, and a resistance actuator configured to impose rotational resistance on the rotatable cutting structure relative to the leg. An earth-boring to may include a plurality of rotatable cutting structure assemblies coupled to the bit body and a plurality of blades coupled to the body. A method of drilling a borehole may include rotating an earth-boring tool within the borehole, causing rotational resistance to be imposed on at least one rotatable cutting structure of the earth-boring tool, causing a blade of the earth-boring tool to be pushed into a sidewall of the borehole, and side cutting the sidewall of the borehole with the blade.
(FR) L'invention concerne un outil de forage pouvant comprendre un corps et au moins un ensemble structure de coupe rotative. La structure de coupe rotative peut comprendre un pied, une structure de coupe rotative accouplée en rotation au pied et un actionneur de résistance conçu pour imposer une résistance à la rotation sur la structure de coupe rotative par rapport au pied. Un outil de forage peut comprendre une pluralité d'ensembles structures de coupe rotatives accouplées au corps de trépan et une pluralité de lames accouplées au corps. L'invention concerne également un procédé de forage d'un trou de forage, pouvant consister à faire tourner un outil de forage dans le trou de forage, amener à imposer une résistance à la rotation sur au moins une structure de coupe rotative de l'outil de forage, amener une lame de l'outil de forage à être poussée dans une paroi latérale du trou de forage et couper latéralement la paroi latérale du trou de forage avec la lame.
