摘要： Systems, program product, and methods are provided which include analyzing the drillability of a subterranean formation and a database of performance characteristics for drilling bits to facilitate bit design optimization and selection for that formation. Using component subterranean formation data, computer models can be generated for the drillability of a target section in terms of physical, mechanical, and micro-structural properties, and for postulated suitable drilling bit performance characteristics based on physical, mechanical, and micro-structural properties of the target section. The drilling bit performance characteristics are then updated by quantifying effects of the drilling system to be employed. Each performance characteristic can be normalized and plotted on its own axis for easy comparison. Next, a candidate drilling bit design is selected from a library of computer models of drilling bit characteristics for a suite of drilling bit designs. An optimization of the drilling bit design may be also performed.

摘要： A reaming apparatus for enlarging a borehole, including a tubular body having one or more longitudinally and generally radially extending blades circumferentially spaced thereabout. Each of the blades carries highly exposed cutting elements, on the order of fifty percent exposure, on its profile substantially all the way to the gage. At least one of the blades is a primary blade for cutting the full or drill diameter of the borehole, while one or more others of the blades may be secondary blades which extend a lesser radial distance from the body than the primary blade. A secondary blade initially shares a large portion of the cutting load with the primary blade while the borehole size is in transition between a smaller, pass through diameter and drill diameter. It functions to enhance the rapidity of the transition while balancing side reaction forces, and reduces vibration and borehole eccentricity. After drill diameter is reached, cutting elements on the secondary blade continue to share the cutting load over the radial distance they extend from the body.

摘要： A cutting structure for use in a rotary drag bit for downhole drilling is disclosed which relieves stress concentrations focused in the cutting structure along a line adjacent the surface where a cutting element abuts the carrier element or stud. A semicircular polycrystalline diamond compact (PDC) cutting element segment and a cooperating blank segment are diametrically bonded together and, in turn, bonded to a surface on the carrier element. The PDC segment has a chamfer formed along one inner edge, and the blank segment similarly has a chamfer formed along one inner edge. The two segments are joined together along their chamfered edges so that the chamfers are aligned to form a channel through the cutting structure when the segments are bonded to the carrier element. A groove may also be formed in the carrier element along the line where the polycrystalline diamond cutting element, the blank segment and the carrier element are joined, either in addition to or in lieu of the chamfers. The chamfers (and/or optional groove) thereby form a channel through the cutting element which relieves stress concentrations at the line of intersection of the cutting structure components. Another embodiment utilizes a carrier element with a shelf recess in which the PDC segment resides and no blank segment. The inner edge of the shelf or recess includes a radiused undercut extending within the carrier element, which undercut cooperates with the PDC segment chamfer to form the channel.

摘要： A rotary drill bit comprising a bit body having a chamber therein adapted to receive drilling fluid under pressure, a plurality of nozzles in communication with the chamber for exit of the drilling fluid, and a plurality of depending legs at its lower end, each having a bearing journal. The bit further includes a plurality of roller cutters, one for each leg, each cutter comprising a generally conical cutter body rotatably mounted on the bearing journal of the respective leg, and a plurality of cutting elements thereon. Each nozzle has an orifice in a position below the top of an adjacent roller cutter but above the central axis of the respective bearing journal at its inner end with respect to the bit body. In addition, each nozzle directs the fluid to flow in the direction opposite the direction of rotation of the bit, with the flow being generally tangent to the cutter body of the adjacent roller cutter, and thereafter impinging portions of the bottom of the well bore immediately forward of the adjacent roller cutter, whereby the drilling fluid cleans these portions of the well bore bottom and the cutting elements immediately prior to their engagement for enhanced drill bit cutting action.

摘要： A drill string component includes a box-end and a pin-end. Each end includes a signal transceiver, which are operably coupled together. Each signal transceiver communicates with another signal transceiver in another component to form a communication network in the drillstring. An end-cap may be placed in the central bore of the pin-end of a component to form an annular chamber between a side of the end-cap and a wall of the central bore of the pin-end when the end-cap is disposed in the central bore. In some embodiments, an electronics module may be placed in the annular chamber and configured to communicate with one of the signal transceivers. Accelerometer data, as well as other sensor data, at various locations along the drillstring may be sampled by the electronics module and communicated to a remote computer. Drillstring motion dynamics, such as vibration, may be determined based on the accelerometer data.
