摘要： A method for presenting drilling information includes presenting a display including a graph having a first axis and a second axis. The first axis represents a rate of penetration (ROP) of a drill bit into a borehole and the second axis representing a mechanical specific energy (MSE) of a drilling system that includes the drill bit. The method also includes plotting time based or foot based data with a computing device for one or more drilling runs on the graph and overlaying the graph with lines of constant power.

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.
