Title
(EN) MACROSCOPIC DRILL BIT REINFORCEMENT
(FR) RENFORT DE TRÉPAN MACROSCOPIQUE
Abstract
(EN)
In accordance with embodiments of the present disclosure, systems and methods for manufacturing a macroscopically reinforced metal-matrix composite (MMC) fixed-cutter bit are provided. The reinforced drill bit may include a bit body constructed from an infiltrated MMC material and featuring several blade portions extending radially outward and downward from a shank of the drill bit. These blade portions are designed for contacting a subterranean formation. The drill bit also includes the shank, which is coupled to an end of the bit body opposite the blade portions, to connect the bit body to an upstream component of a drill string. The drill bit further includes a number of macroscopic bit reinforcements that are at least partially enclosed within the bit body. These bit reinforcements are each disposed in and aligned substantially with a corresponding blade portion of the bit body.

Dans des modes de réalisation, l'invention concerne des systèmes et des procédés de fabrication de trépan à mollettes composite à matrice métallique renforcé macroscopiquement (MMC). Le trépan renforcé peut comprendre un corps de trépan construit à partir d'un matériau MMC infiltré, et présentant plusieurs parties de lame s'étendant radialement vers l'extérieur et vers le bas à partir d'une tige de trépan. Les parties de lame sont conçues pour entrer en contact avec une formation souterraine. Le trépan comprend également la tige qui est couplée à une extrémité du corps de trépan opposée aux parties de lame pour relier le corps de trépan à un composant en amont d'un train de tiges de forage. Le trépan comprend en outre un certain nombre de renforts de trépan macroscopiques qui sont au moins partiellement renfermés à l'intérieur du corps de trépan. Les renforts de trépan sont disposés chacun dans une partie de lame correspondante du corps de trépan avec laquelle ils sont sensiblement alignés.
