CA 2125335

A rotary cone rock bit for drilling boreholes in an earthen formation is disclosed. One or more rotary cones are rotatably retained on a journal bearing connected to the rock bit. These rotary cones form a circumferential heel row with extended ultra hard shaped cutters spaced within the heel row. Each of the shaped cutters form a cutting surface that extends above the heel row or is angled with respect to the formation to maintain the cutters in compression while the cutters shear a borehole wall. The shaped cutters serve to maintain the borehole diameter.

La présente invention pour objet un trépan à cônes pour le forage de trous dans une formation géologique. Un ou plusieurs cônes sont maintenus avec mouvement rotatif sur un tourillon relié au trépan. Ces cônes rotatifs forment un talon périphérique avec molettes en matériau ultra-dur espacées à l'intérieur du talon. Chacune des molettes forme une surface de coupe qui s'étend du dessus du talon ou qui forme un angle par rapport par rapport à la formation afin de maintenir les molettes en compression pendant qu'elles cisaillent les parois d'un trou. Les molettes formées servent à maintenir le diamètre du trou foré.
