摘要： A drill bit may include a bit body including at least one blade extending at least partially over a cone region of the bit body. Additionally, the drill bit may include a plurality of cutting structures mounted to the at least one blade and a rubbing zone within the cone region of the at least one blade, wherein cutting structures within the rubbing zone have a reduced average exposure. Additionally, a method of directional drilling may include positioning a depth-of-cut controlling feature of a drill bit away from a formation to prevent substantial contact between the depth-of-cut controlling feature and rotating the drill bit off-center to form a substantially straight borehole segment. The method may also include positioning the depth-of-cut controlling feature of the drill bit into contact with the formation to control the depth-of-cut and rotating the drill bit on-center to form a substantially nonlinear borehole segment.

摘要： A bearing block is provided that may be used with a drag bit body or frame to limit depth of cut of cutters on a bit. The bearing block is designed so that it may be interchangeably replaced or repaired without necessitating alteration to a standardized bit frame. The interchangeable bearing block may be used to provide a target depth of cut (TDOC) and/or a selected contact or rubbing area to support weight on bit and limit depth of cut (DOC) for improving drilling performance of a bit. The interchangeable bearing block brings manufacturing selectability by providing a customizable product in terms of depth of cut selection and cutter penetration control for different formations, which is suitable for use with a common bit frame. A rotary drill bit assembly, a unitary cone insert bearing block for a drill bit, and a bit frame are also provided.

摘要： A method, apparatus and computer-readable medium for drilling a wellbore is disclosed. A fluid is pumped to rotate a drilling assembly at an end of a drill string in the wellbore. A plurality of measurements of pressure of the fluid is obtained. A standard deviation of the mud pressure is estimated from the plurality of fluid pressure measurements, and a variation of a tool face angle of the drilling assembly to the pumped fluid is estimated from a comparison of the estimated standard deviation of pressure to a selected criterion. A drilling parameter can be altered to drill the wellbore based on the estimated variation of the tool face angle.

摘要： Earth-boring tools include a cutting element mounted to a body that comprises a metal or metal alloy, such as steel. A cutting element support member is mounted to the body rotationally behind the cutting element. The cutting element support member has an at least substantially planar support surface at a first end thereof, and a lateral side surface extending from the support surface to an opposing second end of the cutting element support member. The cutting element has a volume of superabrasive material on a first end of a substrate, and a lateral side surface extending from the first end of the substrate to an at least substantially planar back surface. The at least substantially planar back surface of the cylindrical substrate abuts an at least substantially planar support surface of the cutting element support member.
