Abstract
A drill bit includes a bit body providing one or more blades and defining a cone section extending from a centerline of the bit body a first distance, a nose section extending from the cone section a second distance, a shoulder section extending from the nose section a third distance, and a gauge section extending from the shoulder section a fourth distance. The drill but further includes one or more cutting elements mounted to the one or more blades outside of the cone section such that the cone section is void of cutting elements, and a plurality of milling elements secured to the bit body within the cone section.
Claims14
A drill bit, comprising:
- a bit body providing one or more blades and defining a cone section extending from a centerline of the bit body a first distance, a nose section extending from the cone section a second distance, a shoulder section extending from the nose section a third distance, and a gauge section extending from the shoulder section a fourth distance;
- one or more cutting elements mounted to the one or more blades, each cutting element being received within and bonded to a dedicated cutter pocket defined by the bit body, wherein each cutting element is mounted outside of the cone section such that the cone section is void of cutting elements and cutter pockets;
- and
- a plurality of milling elements secured to the bit body within the cone section and further secured to the one or more blades offset from a leading face thereof within at least one of the nose, shoulder, and gauge sections,
- wherein each milling element is made of a wear-resistant material exhibiting jagged or sharp geometry.
A method of using a drill bit, comprising:
- introducing the drill bit into a wellbore, the drill bit including:
- a bit body providing one or more blades and defining a cone section extending from a centerline of the bit body a first distance, a nose section extending from the cone section a second distance, a shoulder section extending from the nose section a third distance, and a gauge section extending from the shoulder section a fourth distance;
- one or more cutting elements mounted to the one or more blades, each cutting element being received within and bonded to a dedicated cutter pocket defined by the bit body, wherein each cutting element is mounted outside of the cone section such that the cone section is void of cutting elements and cutter pockets;
- and
- a plurality of milling elements secured to the bit body within the cone section and further secured to the one or more blades offset from a leading face thereof within at least one of the nose, shoulder, and gauge sections, each milling element being made of a wear-resistant material exhibiting jagged or sharp geometry;
- advancing the drill bit to a wellbore isolation device anchored within the wellbore;
- and
- drilling and milling through the wellbore isolation device with the drill bit.
A drill bit, comprising:
- a bit body providing one or more blades and defining a cone section extending from a centerline of the bit body a first distance, a nose section extending from the cone section a second distance, a shoulder section extending from the nose section a third distance, and a gauge section extending from the shoulder section a fourth distance;
- one or more cutting elements mounted to the one or more blades, each cutting element being received within and bonded to a dedicated cutter pocket defined by the bit body, wherein each cutting element is mounted outside of the cone section such that the cone section is void of cutting elements and cutter pockets;
- a plurality
- of milling elements secured to the bit body within the cone section such that the nose, shoulder, and gauge sections are each void of the plurality of milling elements,
- wherein each milling element is made of a wear-resistant material exhibiting jagged or sharp geometry.
