摘要: A system or method for drilling includes autonomously controlling a rotary or percussive drilling process as it transitions through multiple materials with very different dynamics. The method determines a drilling medium based on real-time measurements and comparison to prior drilling data, and identifies the material type, drilling region, and approximately optimal setpoint based on data from at least one operating condition. The controller uses these setpoints initially to execute an optimal search to maximize performance by minimizing mechanical specific energy. Near-bit depth-of-cut estimations are performed using a machine learning prediction deployed in an embedded processor to provide high-speed ROP estimates. The sensing capability is coupled with a near-bit clutching mechanism to support drilling dysfunction mitigation.

摘要: A suppression module, a suppression assembly, and a drilling tool are disclosed. The suppression module includes a spindle having a first end and a second end, an ear plate slideably disposed between the first end and the second end, a spring positioned between the ear plate and the first end, and an activation mechanism coaxially disposed around the second end of the spindle. The activation mechanism engages the ear plate, activating the spring, or disengages the ear plate, deactivating the spring. The suppression assembly includes at least two suppression modules in series coupled to a processor. The suppression modules are activated or deactivated by the processor, each of the suppression modules being activated or deactivated independent of the other suppression modules. The drilling tool includes a drill pipe, a drill bit, a vibration sensor, and a suppression assembly between the drill pipe and the drill bit.

摘要: A coating architecture is disclosed that includes a substrate having a surface finish Ra of 0.3μ or finer, an intermediate layer overlying and in contact with the substrate; and a solid lubricant layer overlying and in contact with the intermediate layer. The test results of applying the coating architecture to a reciprocating hammer drill utilizing the coating is also disclosed.

摘要: A drilling assembly for downhole to surface communications is provided. The drilling assembly includes a series of pipe segments coupled in fluid communication between a slip ring assembly and an end pipe portion. The slip ring assembly is coupled in data and fluid communication with the pipe segments. A surface communications link is in data communication with the drilling assembly via the slip ring assembly. An end pipe portion is coupled with the drilling assembly that includes an electronics assembly with electronic components for transferring data to the slip ring assembly via the drilling assembly. A drill bit is operably coupled with the end pipe portion for drilling a borehole. Each pipe segment includes an outer conductor portion, a hollow inner conductor portion, and a dielectric portion for electrical isolation between the outer conductor portion and the inner conductor portion.

摘要: A modular anti-rotation device for preventing rotation with respect to the central axis of a drilling tool in a borehole and for producing a notch in a borehole surface. The anti-rotation device includes an upper fixture portion and a lower fixture portion in axial alignment. The upper fixture portion and the lower fixture portion are connected by yoke assemblies. Each yoke assembly is connected to the fixture portion and fixture portion at one end, and forming an articulated joint of the upper yoke assembly and the lower yoke assembly at a distal end opposite the first end. A roller is connected at each joint, connecting the upper and lower yoke assemblies. The rollers engage vertically with a borehole surface, the rollers travelling axially, as a drill shaft penetrates into the borehole, the rollers simultaneously preventing radial movement of the anti-rotation device and prevent rotation with respect to the central axis of the borehole.

摘要: Drilling tools are frequently subject to rotation with respect to the central drilling axis caused by torque. A mechanical linkage can be configured to apply force that is proportional to the weight-on-bit on the borehole surface while transmitting axial loads used to generate weight-on-bit. The device can be used to manage drill string twist that could lead to drilling dysfunctions.
