CA 2753218

A rotary drill bit for drilling formations in dry-drilling environments is disclosed. The rotary drill bit may include a bit body rotatable about a central axis. The rotary drill bit may also include at least one cutting element coupled to the bit body. The at least one cutting element may have a cutting face, a cutting edge adjacent the cutting face, and a back surface opposite the cutting face. The at least one cutting element may be oriented so that a substantial portion of the cutting edge has a positive clearance angle, which may be defined by a first vector that is normal to the cutting face and a second vector that is tangential to a helical path traveled by the cutting edge during drilling.

L'invention porte sur un trépan rotatif pour forer des formations dans des environnements de forage à sec. Le trépan rotatif peut comprendre un corps de trépan apte à tourner suivant un axe central. Le trépan rotatif peut également comprendre au moins un élément de coupe couplé au corps de trépan. Le au moins un élément de coupe peut présenter une face de coupe, un bord de coupe adjacent à la face de coupe, et une surface arrière opposée à la face de coupe. Le au moins un élément de coupe peut être orienté de telle sorte qu'une partie substantielle du bord de coupe a un angle de dépouille positif, qui peut être défini par un premier vecteur qui est perpendiculaire à la face de coupe et un second vecteur qui est tangentiel à un trajet hélicoïdal parcouru par le bord de coupe durant le forage.
