摘要： A reamer bit for use in earth boring operations comprising a body, cutter mounts having rolling cutters on the bit body, and stabilizers pads on the body placed between adjacent cutter mounts. The reamer may further include a pilot bit on a drill pipe extending downward from the reamer body. The reamer bit outer periphery with its stabilizers and bit body has a radial profile approximating a circle thereby reducing dynamic perturbations during drilling operations.

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.
