摘要： A rotating control device can include a housing assembly, a body and a clamp device which releasably secures the housing assembly to the body. The clamp device can include a piston which radially displaces a clamp section. A well system can include a rotating control device which includes at least one seal which seals off an annulus between a body of the rotating control device and a tubular string which extends longitudinally through the rotating control device. The rotating control device can also include a piston which displaces longitudinally and selectively clamps and unclamps a housing assembly to the body.

摘要： An RCD can include a housing assembly containing a bearing assembly and a rotating seal which seals an annulus between a tubular string and a body of the RCD, and a remotely operable clamp device which selectively permits and prevents displacement of the housing assembly relative to the body. A method of remotely operating a clamp device can include rotating a threaded member which is secured relative to an RCD body, and displacing a clamp section in response to the threaded member rotation, thereby selectively securing and releasing a bearing assembly and an annular seal relative to the body. Another RCD can include a rotating seal which seals an annulus between a tubular string and a body of the RCD, and a remotely operable clamp device which selectively permits and prevents access to an interior of the body, the clamp device including a motor which rotates a threaded member.

摘要： A well drilling method can include transporting a pressure optimization unit to a rig site, the pressure optimization unit including a choke manifold, a control system which automatically controls operation of the choke manifold, and a flowmeter which measures flow of drilling fluid through the choke manifold, and then interconnecting the pressure optimization unit to rig drilling equipment. A pressure optimization unit for use with a well drilling system can include a choke manifold, a control system which automatically controls operation of the choke manifold, and a flowmeter which measures flow of drilling fluid through the choke manifold. The choke manifold, control system and flowmeter may be incorporated into a same conveyance which transports the pressure optimization unit to a rig site.

摘要： A method of maintaining a desired temperature at a location in a well can include adjusting fluid circulation parameters, thereby reducing a difference between an actual temperature at the location and the desired temperature. A well system can include at least one sensor, an output of the sensor being used for determining a temperature at a location in a well, and a hydraulics model which determines a desired change in fluid circulation through the well, in response to the temperature at the location being different from a desired temperature at the location. Another method of maintaining a desired temperature at a location in a well can include adjusting a density, solids content and/or flow rate of a fluid circulated through the well, thereby urging a temperature at the location toward the desired temperature.
