Title (EN) ROTARY DRILL BITS WITH PROTECTED CUTTING ELEMENTS AND METHODS
(FR) TRÉPANS ROTATIFS MUNIS D'ÉLÉMENTS TRANCHANTS PROTÉGÉS ET LEURS PROCÉDÉS
Abstract: front page image
(EN)A rotary drill bit with cutting elements operable to control depth of cut and rate of penetration during formation of a wellbore are provided. Respective sets of secondary cutting elements and primary cutting elements may also be disposed on exterior portions of a rotary drill bit. A number of blades may extend from exterior portions of the drill bit with a number of cutting elements disposed on exterior portions of each blade. Each cutting element may include a substrate with a cutting surface disposed thereon. A respective protector may extend from the cutting surface of one or more cutting elements to limit depth of penetration of the associated cutting element into adjacent portions of a downhole formation and/or to control rate of penetration of an associated rotary drill bit.
(FR)L'invention se rapporte à un trépan rotatif muni d'éléments tranchants pouvant servir à contrôler la profondeur et le taux de pénétration lors du forage d'un puits. Des ensembles d'éléments tranchants secondaires et primaires peuvent également être disposés sur les zones extérieures d'un trépan rotatif. Plusieurs lames peuvent partir des zones extérieures du trépan, plusieurs éléments tranchants étant disposés sur les zones extérieures de chaque lame. Chaque élément tranchant peut inclure un support sur lequel est prévue une surface de coupe. La surface de coupe de chacun des éléments tranchants peut être pourvue d'un protecteur individuel servant à limiter la profondeur à laquelle l'élément tranchant qui lui est associé pénètre dans les zones adjacentes d'un trou vers le bas et/ou servant à contrôler le taux de pénétration d'un trépan rotatif qui lui est associé.
