摘要： A rotary steerable tool may include a tool body with an upper end and a lower end. Additionally, the tool body may include at least one steering assembly extending from the tool body and includes at least one steering actuator configured to extend beyond other portions of the steering assembly. Furthermore, at least one cutter may be disposed on the rotary steerable tool a distance from the at least one steering actuator.

摘要： A method for drilling a subterranean wellbore includes rotating a bottom hole assembly (BHA) in the wellbore to drill. The BHA includes a rotary steerable tool or a steerable drill bit having at least one external pad configured to extend radially outward into contact with a wall of the wellbore and thereby steer the drilling. A rotation rate of the BHA is measured and a drilling parameter waveform is received. The rotation rate and the waveform are processed to select discrete times for extending the at least one external pad while drilling.

摘要： A downhole steering system includes a substantially tubular housing, a shaft positioned within the substantially tubular housing, a first bearing and a second bearing, the first and second bearings being configured to support rotation of the shaft relative to the housing. The first bearing, the second bearing, the shaft, and the housing at least partially define a chamber therebetween. The system also includes at least one structure positioned axially between the first and second bearing and being configured to extend from an exterior of the housing in response to pressure communicated to the chamber.

摘要： A method for evaluating a subterranean wellbore includes rotating a drill string in the subterranean wellbore. The drill string includes a rotary steerable tool, a steerable drill bit, or other rotary steering tool with at least one pad configured to extend radially outward from a tool body and engage a wall of the wellbore. Radial displacements of the pad are measured while rotating and processed to compute a curvature of the wellbore.

摘要： A method can include acquiring drilling performance data for a downhole tool; modeling drilling performance of the downhole tool to generate results; training a machine learning model using the drilling performance data and the results to generate a trained machine learning model; and predicting behavior of the downhole tool using the trained machine learning model.

摘要： A method for removing material with a bit includes rotating a bit in a first direction, changing the rotational direction and rotating the bit in an opposing second direction. Rotation of the bit in the first direction and rotation of the bit in the second direction both remove material.

摘要： A mud motor includes a rotor and a stator. Drilling fluid received by cavities of the mud motor drives the rotor to rotate within the stator. The rotor includes one or more rotor lobes extending helically and defining a rotor pitch. The stator includes two or more stator lobes extending helically and defining a stator pitch. The rotor and the stator together define a tapered profile of the mud motor that varies proceeding from a top end of the mud motor to a bottom end of the mud motor. At least one of the rotor pitch or the stator pitch vary as proceeding from the top end of the mud motor to the bottom end of the mud motor.
