| description | A drill bit for drilling a wellbore, the drill bit having a cutter which has tungsten carbide inserts and a spear point. The spear point has a neck that joins a smooth portion of the cutter and blades that extend from the neck and converge to an apex. The blades define valleys or spaces between them. A layer of hardfacing is applied to the entire spear point including the interim spaces and the neck.
L'invention concerne un trépan pour forer un puits de forage, le trépan ayant un dispositif de découpe qui a des inserts de carbure de tungstène, et une pointe de harpon. La pointe perçante a un col qui rejoint une partie lisse du dispositif de découpe, et des lames qui s'étendent depuis le col et convergent vers un sommet. Les lames définissent des vallées ou espaces entre celles-ci. Une couche de revêtement dur est appliquée sur toute la pointe de harpon, y compris les espaces intermédiaire et le col. |
