Title (EN) CUTTING REMOVAL SYSTEM FOR PDC DRILL BITS
(FR) SYSTÈME DE SUPPRESSION DES DÉCOUPES POUR TRÉPANS PDC
Abstract:
(EN) The blades of a PDC bit have a nozzle between them preferably oriented laterally across the plane of the cutters on the blade and more preferably in a trough disposed adjacent the row of cutters. The cutting is less likely to adhere to the bit surface because the trough abruptly spaces back the bit surface and the spray being oriented radially preferably into the trough gets between the bit surface and the cutting before it can adhere to the bit surface using the fluid energy to drive the cutting into the junk slot.
(FR) Une buse est placée entre les lames d'un trépan PDC, et cette buse est de préférence orientée latéralement dans le plan des parties coupantes sur la lame, et plus préférentiellement dans un creux voisin de la rangée de parties coupantes. Les découpes sont moins susceptibles d'adhérer à la surface du trépan car le creux se sépare brusquement de la surface du trépan, et les projections, orientées de manière radiale, de préférence dans le creux, s'insèrent entre la surface du trépan et les découpes avant que ces dernières ne puissent adhérer à la surface du trépan, l'énergie de fluide entraînant les découpes dans la fente de repêchage.
