Definitions

  • the invention relates generally to the control of heating from adiabatic compression within pressurized vessels and components associated with a wellhead.
  • Wellheads typically include pressure control vessels, such as those that are used to equalize pressure across a wellhead valve prior to opening the valve. Undesirable adiabatic heating may occur within these vessels during operation.
  • the invention provides systems and methods for controlling and reducing adiabatic heating within pressure control equipment.
  • the systems and methods of the present invention reduce adiabatic heating by venting the pressure control equipment either during or prior to compression of fluid within the pressure control equipment.
  • the venting removes or substantially removes compressible gases from the pressure control equipment.
  • venting is performed by a valve that is positioned to remove compressible gases at or near the upper end of
  • valve components are formed of materials that are resistant to corrosive fluids, and in particular hydrogen sulfide (H 2 S).

  • corrosion-resistant plastics, thermoplastics, ceramic materials and nickel alloys are preferred.
  • a wellhead for wireline run devices includes pressure control equipment in the form of a lubricator that is used to equalize pressure across the wellhead master valve prior to fully opening the wellhead master valve.
  • a vent valve assembly is designed to remove compressible gases from the interior chamber of the lubricator prior to fully opening the master valve, In a described embodiment, the vent valve assembly removes compressible gases from the interior chamber during the time that the wellhead master valve is partially opened to pressurize the interior chamber. In a preferred embodiment, the valve assembly is positioned to remove compressible gases that reside within the upper portion of the interior chamber. Removed gases may be transmitted to a gas buster or similar device for incineration. In described embodiments, venting occurs until liquid effluent is expelled from the valve. Then the venting valve is closed. Thereafter, the wellhead master valve can be fully opened.
  • a venting system is associated with a coiled tubing injection arrangement to remove compressible gases from pressure control equipment.

It is noted that, for purposes of clarity, Figures 3, 4A and 4B do not show either a wireline cable or a wireline tool.
  • the lubricator 16 is a pressure control device that permits wireline tools to be inserted into and removed from the wellhead 10, which is under pressure. Pressure across the master valve 14 prior to opening can be on the order of around 15,000 psi.
  • the lubricator 16 defines an interior chamber 28 that can be pressurized. The lower end of the interior chamber 28 is defined by the master valve 14. The upper portion 29 of the interior chamber 28 terminates at a vent valve assembly 30.

  • the valve housing 36 also houses valve member 48 which is biased by spring 50 toward the closed position wherein fluid from the lateral passage 46 cannot pass into the exhaust line 32.
  • Hydraulic fluid within hydraulic line 34 will selectively open the valve assembly 30 by urging the valve member 48 to an open position (Fig. 4B) by axial I y compressing the spring 50 to open the flowpath 47 to fluid flow therethrough.
  • a weld overlay may be used to protect the valve member 48 and the interior portions of the valve housing 36 and adapter 38. When hydraulic fluid is no longer flowed into the vent valve assembly 30, the spring 50 will urge the valve member 48 back to the closed position (fig. 4A).
