Abstract

A pressure control device may include a body having a central axis extending therefrom; at least one rotatable seal within the body, the rotatable seal configured to seal against a tubular extending through the pressure control device along the central axis and rotate within the body with the tubular; at least one coil within the body wrapped at least once around the central axis, wherein the at least one coil is configured to send characteristics of the tubular to a controller; an outlet to divert fluid from an annulus, wherein the outlet being located axially below the at least one rotatable seal, wherein the controller is configured to control the at least one rotatable seal and its engagement against the tubular based on the characteristics of the tubular received by the controller.

First claim

What is claimed is:

1. A pressure control device, comprising:
a body having a central axis extending therefrom;
at least one rotatable seal within the body, the rotatable seal configured to seal against a tubular extending through the pressure control device along the central axis and rotate within the body with the tubular;
at least one coil within the body wrapped at least once around the central axis, wherein the at least one coil is configured to send characteristics of the tubular to a controller, and wherein the at least one coil comprises a single coil for transmitting and receiving; and
an outlet to divert fluid from an annulus, wherein the outlet is located axially below the at least one rotatable seal, and wherein the controller is configured to control the at least one rotatable seal and its engagement against the tubular based on the characteristics of the tubular received by the controller.

2. The pressure control device of claim 1 , wherein the at least one coil comprises at least one transmitting coil located above the at least one rotatable seal and at least one receiving coil located below the at least one rotatable seal.

3. The pressure control device of claim 1 , wherein the at least one rotatable seal is actuated by a piston.

4. The pressure control device of claim 3 , further comprising a bearing assembly disposed on an outer radial surface of the piston, thereby providing rotation for the at least one rotatable seal.

5. The pressure control device of claim 3 , further comprising a linear variable differential transformer within the body to measure the position of the piston.

6. The pressure control device of claim 1 at least one sensor within the body, wherein the at least one sensor is configured to send characteristics of the tubular and the at least one rotatable seal to the controller.

7. The pressure control device of claim 6 , wherein at least one sensor is an ultrasonic sensor, an accelerometer, a hydrophone, a microphone, and/or a tangent strain gauge.

8. The pressure control device of claim 1 , further comprising a rotary compression system attached within the body by a first bearing assembly and a rotary support attached within the body by a second bearing assembly, thereby providing for rotation of the at least one rotatable seal.

9. The pressure control device of claim 8 , wherein the at least one rotatable seal is located between the rotary compression system and the rotary support.

10. The pressure control device of claim 8 , further comprising a non-rotary activation piston within the body above the rotary compression system.

11. The pressure control device of claim 10 , further comprising a linear variable differential transformer within the body to measure the position of the non-rotary activation piston.

12. The pressure control device of claim 1 , further comprising at least two or more rotatable seals within the body, wherein each is configured to seal against a body of the tubular and open when a connection between two tubulars passes therethrough.

13. A pressure control device, comprising:
a body having a central axis extending therefrom;
at least one rotatable seal within the body, the rotatable seal configured to seal against a tubular extending through the pressure control device along the central axis and rotate within the body with the tubular;
at least one coil within the body wrapped at least once around the central axis, wherein the at least one coil is configured to send characteristics of the tubular to a controller;
an outlet to divert fluid from an annulus, wherein the outlet is located axially below the at least one rotatable seal, wherein the controller is configured to control the at least one rotatable seal and its engagement against the tubular based on the characteristics of the tubular received by the controller; and
at least one slot in the body to hold the at least one coil, the at least one coil configured to detect movement of a metal tooth attached to the at least one rotatable seal.

14. A pressure control device, comprising:
a body having a central axis extending therefrom;
at least one rotatable seal within the body, the rotatable seal configured to seal against a tubular extending through the pressure control device along the central axis and rotate within the body with the tubular;
at least one coil within the body wrapped at least once around the central axis, wherein the at least one coil is configured to send characteristics of the tubular to a controller; and
an outlet to divert fluid from an annulus, wherein the outlet is located axially below the at least one rotatable seal, and wherein the controller is configured to control the at least one rotatable seal and its engagement against the tubular based on the characteristics of the tubular received by the controller;
a rotary compression system attached within the body by a first bearing assembly and a rotary support attached within the body by a second bearing assembly, thereby providing for rotation of the at least one rotatable seal, wherein the at least one rotatable seal is located between the rotary compression system and the rotary support; and
a non-rotary activation piston within the body above the rotary compression system, wherein the non-rotary activation piston is actuated by an oil pressure, thereby compressing the rotary compression system and the rotary support on the at least one rotatable seal.
