Drill bit having rotational cutting elements and method of drilling
摘要:
A rotary drill bit is disclosed. The rotary drill bit may include a bit body, a cutting pocket defined in the bit body, and a cutting element rotatably coupled to the bit body. The cutting element may be positioned at least partially within the cutting pocket. The rotary drill bit may also include a rotation-inducing member adjacent to the cutting element for inducing rotation of the cutting element relative to the cutting pocket. The rotation-inducing member may include a resilient member or a vibrational member. The rotary drill bit may also include protrusions extending from an interior of the cutting pocket adjacent to an outer diameter of the cutting element. A method of drilling a formation is also disclosed.
