    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 reamer bit for use in earth boring operations comprising a body, four cutter mounts, rolling cutters on each mount, and cutting elements disposed on each cutter arranged so adjacent cutting swaths formed by the bit are created by cutting elements on cones of oppositely disposed cutter mounts. The swaths are generally curvilinear, wherein the outermost swaths are formed by cutting element rows on the outer portion of the cutters. The reamer bit can further comprise a pilot bit.

    摘要： The harmful effects of tracking are reduced for a drill bit having roller cones with at least one of the outermost rows of active teeth containing one or more teeth having a height that does not extend to the height of at least one of the outermost rows on another roller cone on the bit. The crest on this tooth may have a length in a circumferential direction that is wider than an overall width of the tooth in the outer to inner direction. The invention may be used on any cutter row, not just the outermost row. The design may be used on a different roller cone or row, or more than one cutter row. The anti-tracking feature may be located between the leading and trailing edges of the tooth on one or more roller cones.

    摘要： Methods of forming earth-boring tools include assembling a plurality of head sections about a longitudinal axis to form a bit body, rotatably mounting a cutter to a cutter bearing shaft of each head section, and forming at least one groove on an outer surface of a bit leg of at least one head section, causing the at least one groove to extend along a curved path from a leading side of the bit leg to a trailing side of the bit leg between an upper sidewall and a lower sidewall.

    摘要： A hybrid drill bit may have a bit body, at least one blade extending longitudinally and radially outward from the face, at least one rolling cutter assembly mounted on the bit body, at least one primary cutter, and at least one cutter set including a first cutter and a second cutter. The cutter set may be positioned to substantially follow the at least one primary cutter along the cutting path upon rotation of the bit body. At least one cutter of the cutter set may have a high side rake angle.

    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.
