摘要： In one aspect of the invention a rotary drag bit has a bit body intermediate a shank and a working surface. The working surface has a plurality of blades converging at a center of the working surface and diverging towards a gauge of the working surface. At least one blade has a cutting element with a carbide substrate bonded to a diamond working end with a pointed geometry. The diamond working end has a central axis which intersects an apex of the pointed geometry such that the axis is oriented within a 15 degree rake angle.

摘要： A drill bit assembly comprises a bit body intermediate a shank and a working face. The shank is adapted for connection to a drill string. The drill string comprising a fluid passage at least partially disposed within the body. A hammer assembly is movably disposed within the fluid passage along it central axis, the hammer assembly comprises a proximal end stabilized by a centralized upper bearing and a distal end stabilized by centralized a lower bearing. The distal end protrudes out of the working face and the hammer assembly comprises a carrier between the upper and lower bearings. Wherein, under normal drilling operations the carrier is adapted to resist a fluid pressure within the fluid passageway such that the fluid pressure will further extend the distal end of the hammer assembly from the working face by pushing on the carrier.

摘要： A drill bit has a bit body intermediate a working face and a shank end adapted for connection to a downhole drill string. The working face has at least three fixed blades converging towards a center of the working face and diverging towards a gauge of the bit, at least one blade having a cone region adjacent the center of the working face. The cone region increases in height away from the center of the working face and towards a nose portion of the at least one blade. An opening is formed in the working face at the center of the bit along an axis of the drill bit's rotation, the opening leading into a chamber with at least one wall. An indenting member is disposed within and extends from the opening, is substantially coaxial with the axis of rotation, and is fixed to the wall of the chamber.

摘要： According to an exemplary computer-implemented method, user input is received indicating N regions within a data range of a process parameter, where N is greater than or equal to three. A slide control is displayed representing the data range and the regions within the data range. The slide control includes N−1 sliders, with each slider representing a boundary between two of the regions. Responsive to movement of a selected slider, its associated boundary is reset. An associated computing device and computer program product are also disclosed. In one or more embodiments, the user input includes a label and a display attribute, such as color or shading, for each region to be used for displaying the region.
