Definitions

  • This disclosure relates generally to equipment utilized and operations performed in conjunction with a subterranean well and, in an example described below, more particularly provides a pressure control device and associated methods and systems.
  • a pressure control device may be used to isolate a well annulus from the atmosphere at or near surface, for example, in managed pressure drilling operations.
  • the pressure control device seals off the annulus surrounding a drill string (such as, an annulus between the drill string and an outer tubular riser string) and, in some examples, annular seals that sealingly engage the drill string can rotate with the drill string.
  • US 9 359 853 B2 discloses an acoustic control system wirelessly that operates a subsea latching assembly or other subsea device, such as an active seal.
  • the acoustic control system may control a subsea first accumulator to release its stored hydraulic fluid to operate the latch assembly or other subsea device, such as an active seal.
  • An RCD or other oilfield device may be unlatched or latched with the latching assembly.
  • the acoustic control system may have a surface control unit, a subsea control unit, and two or more acoustic signal devices.
  • a valve may allow switching from an umbilical line system to the acoustic control system accumulator.
  • US 9 051 790 B2 discloses an offshore universal riser system that may include a valve module which selectively permits and prevents fluid flow through a flow passage extending longitudinally through a riser string.
  • An anchoring device may releasably secure the valve module in the passage.
  • a method of constructing a riser system may include the steps of installing the valve module in the passage, and installing at least one annular seal module in the passage.
  • the annular seal module may prevent fluid flow through an annular space between the riser string and a tubular string positioned in the passage.
  • Drilling methods may include injecting relatively low density fluid compositions into the annular space, and selectively varying a restriction to flow through a subsea choke in a drilling fluid return line.
  • the riser string including housings for the various modules and external control systems, may be dimensioned for installation through a rotary table.
  • WO 2015/080727 A1 discloses a bearing assembly that can be releasably secured relative to an outer housing of a rotating control device without using fluid pressure.
  • An example method includes inserting the bearing assembly into an outer housing to outwardly displace a latch engagement member.
  • the engagement member is inwardly biased without fluid pressure, such as with a spring.
  • the assembly is moved to an operative position in the outer housing, at which the inwardly-biased engagement member displaces inwardly to engage a recess on the bearing assembly.
  • Fluid pressure may subsequently be used once the bearing assembly is latched, to optionally help maintain the engagement member in the recess or to move the engagement member out of the recess to unlatch the bearing assembly.
  • CN 106 639 961 A discloses an environment-friendly closed rotary blowout preventer for unbalanced drilling.
  • the rotary blowout preventer is composed of a rotating assembly and a shell.
  • the rotating assembly is installed on the shell through sealing rings to form the environment-friendly closed rotary blowout preventer for unbalanced drilling on the whole.
  • a shell body of the shell is provided with two grooves spaced by 150 degrees.

  • the scope of this disclosure is not limited to any particular details of the latch 46, housing assembly 26 and releasable assembly 40 as described herein or depicted in the drawings.
  • An annular seal assembly 60 is carried on the releasable assembly 40 for sealing between the releasable assembly and the housing assembly 26.
  • the annular seal assembly 60 is sealingly engaged about the releasable assembly 40 and, when the releasable assembly is installed in the housing assembly 26, the annular seal assembly is sealingly engaged in the housing assembly.
  • FIG. 3 a larger scale cross-sectional view of an example of the annular seal assembly 60 operatively positioned between the releasable assembly 40 and the housing assembly 26 in the pressure control device 48 is representatively illustrated.

  • sealing surface 64a extends radially inward farther than each of the support element components 66a,b, and the sealing surface 64b extends radially outward farther than each of the support element components. This enables the seal element 64 sealing surfaces 64a,b to sealingly contact the respective external surface 70 and seal bore 72, and to deflect axially prior to fully engaging the releasable assembly 40 into the housing assembly 26.
  • seal element 64 is depicted in the drawings as being positioned axially between the support element components 66a,b, the seal element could be otherwise positioned in other examples.
  • the seal element 64 could be positioned, for example, in an annular groove or recess internal or external to the support element 66.
  • the pressure control device 48 includes the annular seal assembly 60 that allows the releasable assembly 40 to be positioned and sealed in the housing assembly 26, with damage to or dislodgment of the seal assembly being prevented, or at least mitigated.
