Title (EN) HYBRID DRILL BIT COMPENSATED GAUGE CONFIGURATION
(FR) CONFIGURATION DE JAUGE COMPENSÉE DE TRÉPAN HYBRIDE
Abstract:
(EN) A rotary drill bit includes movable gauge elements biased to protrude radially through a circumferential engagement surface of a gauge pad. The gauge elements are retractable to protrude a lesser distance against the bias of a biasing mechanism. Fluid chambers are defined adjacent the gauge elements, and fluid is permitted to be bled into and out of the fluid chambers to delay and slow the retraction and extension of the gauge elements. During straight drilling operations, the biasing mechanisms maintain the gauge elements in an extended position providing stability to the drill bit. When a steering force is applied to the drill bit, the gauge elements retract slowly as fluid is bled from the fluid chambers. As the gauge elements rotate with the drill bit, the retracted configuration may be maintained as gauge elements disengage the geologic formation on a side of the drill bit opposite the steering direction.
(FR) L'invention concerne un trépan rotatif comprenant des éléments de jauge mobiles sollicités pour faire saillie radialement à travers une surface de mise en prise circonférentielle d'un tampon de jauge. Les éléments de jauge sont rétractables pour faire saillie d'une distance inférieure à la sollicitation d'un mécanisme de sollicitation. Des chambres de fluide sont délimitées adjacentes aux éléments de jauge, et le fluide peut être purgé à l'intérieur et à l'extérieur des chambres de fluide pour retarder et ralentir la rétraction et l'extension des éléments de jauge. Pendant des opérations de forage en ligne droite, les mécanismes de sollicitation maintiennent les éléments de jauge dans une position déployée fournissant une stabilité au trépan. Lorsqu'une force de direction est appliquée au trépan, les éléments de jauge se rétractent lentement lorsqu'un fluide est purgé des chambres de fluide. Lorsque les éléments de jauge tournent avec le trépan, la configuration rétractée peut être maintenue en tant qu'éléments de jauge libérant la formation géologique sur un côté du trépan opposé au sens de direction.
