Abstract
A rotating choke assembly includes a rotating control device and a flow control device. The rotating control device has a seal element configured to be disposed around a tubular, where the seal is configured to rotate in a circumferential direction via rotation of the drill string and a bearing configured to facilitate rotation of the seal element in the circumferential direction within a housing of the rotating control device. The flow control device includes a first plate having at least one first opening and a second plate having at least one second opening, where the first plate is configured to rotate in the circumferential direction with respect to the second plate.
Claims22
A rotating choke assembly, comprising:
- a rotating control device, comprising:
- a seal element configured to seal against a tubular, wherein the seal element is configured to rotate in a circumferential direction via rotation of the tubular;
- and
- a bearing configured to facilitate rotation of the seal element in the circumferential direction within a housing of the rotating control device;
- a flow control device, comprising:
- a first plate comprising at least one first opening;
- and
- a second plate comprising at least one second opening, wherein the first plate is configured to rotate in the circumferential direction with respect to the second plate;
- and
- an actuator configured to drive rotation of the first plate in the circumferential direction with respect to the second plate.

11-17. (canceled)
A rotating choke assembly for a drilling system, comprising:
- a rotating control device, comprising:
- a seal configured to seal against a drill string disposed within a well, wherein the seal is configured to rotate in a circumferential direction via rotation of the drill string;
- and
- a bearing configured to facilitate rotation of the seal in the circumferential direction within a housing of the rotating control device;
- a flow control device, comprising:
- a first plate comprising at least one first opening;
- a second plate comprising at least one second opening, wherein the first plate is configured to rotate in the circumferential direction with respect to the second plate;
- and
- an actuator configured to rotate the first plate in the circumferential direction;
- a sensor configured to monitor an operating parameter within the well;
- and
- a control system communicatively coupled to the sensor and the actuator, wherein the control system is configured to receive feedback from the sensor indicative of the operating parameter within the well and configured to output a control signal to the actuator to rotate the first plate in the circumferential direction based on the feedback.
