Filed:

Nov 18, 2011

Appl. No.:

13/300335

Inventors:

Leonard C. LINDE - Casper WY, US
Reece E. CASHION - Conroe TX, US
Larry D. WHITE - Brenham TX, US

Assignee:

HALLIBURTON ENERGY SERVICES, INC. - Houston TX

International Classification:

E21B 23/00

US Classification:

166381, 1662416

Abstract:

An RCD can include a housing assembly which contains a bearing assembly and an annular seal which rotates and seals off an annulus between a tubular string and an RCD body, a remotely operable clamp device which selectively permits and prevents relative displacement between the housing assembly and the body, and a remotely operable safety latch which selectively permits and prevents unclamping of the clamp device. A method of remotely operating an RCD clamp device can include remotely operating a safety latch which selectively permits and prevents unclamping of the clamp device, and remotely operating the clamp device while the safety latch is in an unlatched position, thereby unclamping a bearing housing assembly from the RCD body. Another RCD can include a remotely operable clamp device which selectively permits access to an RCD body interior, and a remotely operable safety latch which selectively prevents unclamping of the clamp device.

International Classification:

E21B 33/08
E21B 33/064

Abstract:

A rotating control device for a tubular string includes a body, a housing assembly, and a clamp device. An annulus is formed between the body and the tubular string. The housing assembly includes an annular seal configured to seal off an annulus between the tubular string and the body. The clamp device is configured to selectively permit and prevent displacement of the housing assembly relative to the body. The clamp device includes a first clamp section and a second clamp section coupled to and pivotable about a pivot, and a motor positioned between an end of the first clamp section and an end of the second clamp section, wherein the motor is configured to move the ends of the first and second clamp sections relative to each other.
