    摘要： A method and apparatus for predicting the performance of a drilling system for the drilling of a well bore in a given formation includes generating a geology characteristic of the formation per unit depth according to a prescribed geology model, obtaining specifications of proposed drilling equipment for use in the drilling of the well bore, and predicting a drilling mechanics in response to the specifications as a function of the geology characteristic per unit depth according to a prescribed drilling mechanics model. Responsive to a predicted drilling mechanics, a controller controls a parameter in the drilling of the well bore. The geology characteristic includes at least rock strength. The specifications include at least a bit specification of a recommended drill bit. Lastly, the predicted drilling mechanics include at least one of bit wear, mechanical efficiency, power, and operating parameters. A display is provided for generating a display of the geology characteristic and predicted drilling mechanics per unit depth, including either a display monitor or a printer.

    摘要： Geometric compensation techniques are used to improve the accuracy by which features may be located on drill bits formed using particle compaction and sintering processes. In some embodiments, a positional error to be exhibited by at least one feature in a less than fully sintered bit body upon fully sintering the bit body is predicted and the at least one feature is formed on the less than fully sintered bit body at a location at least partially determined by the predicted positional error. In other embodiments, bit bodies of earth-boring rotary drill bits are designed to include a design drilling profile and a less than fully sintered bit body is formed including a drilling profile having a shape differing from a shape of the design drilling profile. Less than fully sintered bit bodies of earth-boring rotary drill bits are formed using such methods.

    摘要： A graphite or silicate plug is coated with a refractory metal and positioned in the cutter pocket of a steel bodied bit as molten hardfacing material is applied to the bit surface under high temperature conditions. The refractory metal cooperates with the hardfacing material to act as a wetting agent that draws the hardfacing material into intimate contact with the body of the displacement plug. The plug is removed leaving a composite pocket opening formed by the steel body and the hardfacing material. A PDC cutter inserted into the composite pocket opening closely adheres to the sides of the opening to reduce the gap between the cutter and the hardfacing material to hereby minimize the effects of erosion in the area of the gap. The wetting material on the displacement plug permits the hardfacing material to flow into and remain in position immediately adjacent the displacement body and in the small surface area between adjacent cutter pockets. The hardfacing material also cooperates with the-steel pocket to increase the surface area of the pocket recess that provides additional structural support to the cutter to improve the stability and retention of the cutter in the bit. The refractory metal may preferably be molybdenum that is applied in a thin layer deposited by a plasma coating technique directly over the body of the graphite displacement body.
