Abstract
(EN)
An earth boring drill bit (10) including replaceable gage pads (28). The gage pads and the corresponding surface of the earth boring drill bit may include complementary securing elements (40,46) which mutually engage one another. The gage pad may be removably affixed to the earth boring drill bit an affixation elements, such as a bolt, a mechanical locking element, brazing, welding, mechanical affixation, or another known technique. The invention also includes a method of testing differently configured gage pads employing a single earth boring drill bit, a method of replacing the gage pads of an earth boring drill bit at the drilling site, a method of customizing an earth boring drill bit to include one or more gage pads of desired configuration, and a method of altering the balance or net imbalance of an earth boring drill bit by replacing at least one gage pad thereof.

L'invention concerne un trépan de foreuse comprenant des portées calibrées remplaçables. Ces portées calibrées et la surface correspondante du trépan de foreuse peuvent comprendre des éléments complémentaires attachables qui s'enclenchent l'un dans l'autre. Cette portée calibrée peut être fixée démontable au trépan de foreuse par des éléments de fixation, tel qu'un boulon, un élément de fermeture mécanique, un brasage, une soudure, une fixation mécanique, ou une autre technique connue. Cette invention concerne aussi un procédé permettant de tester des portées configurées de façon différente en utilisant un seul trépan de foreuse, un procédé permettant de remplacer les portées calibrées d'un trépan de foreuse sur le site de forage, un procédé permettant d'adapter un trépan de foreuse de façon à inclure une ou plusieurs portées de la configuration souhaitée, et un procédé permettant de modifier l'équilibre ou le déséquilibre net d'un trépan de foreuse par remplacement d'au moins une de ses portées calibrées.
