  • ROTARY STEERABLE DRILLING ASSEMBLY AND METHOD
    Publication number: 20240110444
    Abstract: A rotary steerable drilling assembly includes a driveshaft rotatably disposed in a driveshaft housing, a bend adjustment assembly coupled to the driveshaft housing, a bearing mandrel coupled to the bend adjustment assembly, and a torque control assembly including a rotor configured to couple with a drill string; a stator assembly coupled to a downhole motor; and a torque control actuator assembly configured to control the amount of torque transmitted between the rotor and the stator assembly, wherein the torque control actuator assembly includes a spool valve including a cylinder including a port and a hydraulically actuatable piston slidably disposed in the cylinder.

  • Rotary steerable drilling assembly and method
    Patent number: 11879333
    Abstract: A rotary steerable drilling assembly for directional drilling includes a driveshaft rotatably disposed in a driveshaft housing, a bend adjustment assembly coupled to the driveshaft housing, a bearing mandrel coupled to the bend adjustment assembly, and a torque control assembly including a rotor configured to couple with a drill string, a stator assembly coupled to the downhole motor, and a torque control actuator assembly configured to control the amount of torque transmitted between the rotor and the stator assembly, wherein the bend adjustment assembly includes a first position providing a first deflection angle between a longitudinal axis of the driveshaft housing and a longitudinal axis of the bearing mandrel, wherein the bend adjustment assembly includes a second position providing a second deflection angle between the longitudinal axis of the driveshaft housing and the longitudinal axis of the bearing mandrel, the second deflection angle being different from the first deflection angle.
    Type: Grant
