Abstract
Description
- This application claims priority to U.S. Application No. 62/987,677 filed on Mar. 10, 2020, the disclosure of which is incorporated herein by reference for all purposes.
- The present invention relates to a lubricator for installing and extracting a valve removal plug (VR plug) in a wellhead. More particularly, the present invention relates to a lubricator for installing and extracting a VR plug in a wellhead positioned in a cellar or other narrow, constricted location.
- When a valve of a wellhead needs repair or replacement a VR plug is often employed. The VR plug is inserted through the open valve(s) and is ultimately positioned, generally by threading it into position, in the wellhead such that the valve in need of repair is sealed off from fluid flow. Typically, a VR plug is installed using a lubricator attached to the horizontal valve. The lubricator is a long tube which holds pressure while moving an internal tool rod to position and remove the VR plug. Lubricators are well known to those skilled in the art and are often used in running and retrieving operations on a wellhead to manage wellhead pressure during the operation. Examples of prior art lubricators can be found in US 2012/0024521 and U.S. Pat. No. 6,827,147, both of which are incorporated herein by reference for all purposes. When a wellhead is installed below ground level, e.g., in a cellar, there is not enough clearance for the traditional lubricator installation/removal method. Thus operators must dig out an area in the side of the cellar large enough to accommodate the installation and removal of the VR plug. Alternatively, a specialized lubricator, e.g., a telescoping lubricator, which is small enough to fit in the cellar area can be employed. The working conditions in the cellar with the specialized lubricator are still quite cramped.
- In one aspect, the present invention relates to a tool for installing a VR plug into a horizontal valve of a wellhead.
- In another aspect, the present invention relates to a tool for installing and extracting a VR plug into a horizontal valve of a wellhead.
- In yet another aspect, the present invention relates to a tool a for installing and extracting a VR plug to and from a horizontal valve of a wellhead positioned in a cellar or other cramped space.
- In still another aspect, the present invention relates to a tool a for installing and extracting a VR plug to and from a horizontal valve of a wellhead positioned below ground level, the tool being operable from ground level.
- These and further features and advantages of the present invention will become apparent from the following detailed description, wherein reference is made to the figures in the accompanying drawings.
-
FIG. 1 shows a wellhead positioned in a cellar with the tool of the present invention being lowered down. -
FIG. 2 shows the tool of the present invention lowered into the cellar and connected to the wellhead. -
FIG. 3 is a cross-sectional view of the tool of the present invention connected to the wellhead. -
FIG. 4 is an enlarged cross-section of the tool of the present invention and the VR plug in position in the wellhead. - Referring first to
FIG. 1 there is shown a wellhead W positioned within cellar C. As can be seen, there is not much distance between the valves V of wellhead W and the walls of cellar C. The lower end of the tool shown generally as 10 is seen near the upper end of cellar C. To replace or repair one of the valves V, a valve removal (VR) plug is installed to cut off fluid from that valve. Typically, the wellhead outlet connected to the valves has female threads for receiving a threaded VR plug. It will be appreciated that not all the features of a typical wellhead are depicted in the drawings, but such features are common and well understood to those skilled in the art. - Turning to
FIGS. 2 and 3 , thetool 10 of the present invention has been connected to a valve V, typically a gate valve, of wellhead W. Thetool 10 comprises alubricator 12 connected by elongatetubular housing 16 to anelbow joint 14. Lubricator 12 compriseslubricator barrel 11,tool rod 13,fitting 15, andaccess window 17.Tool rod 13 extends through barrel 1, fitting 15, and accesswindow 17. As will be explained in detail later,tool rod 13 is axially (longitudinally) movable relative tobarrel 11. Whiletool rod 13 can be axially moved manually using a pipe wrench, e.g., a Parmelee wrench or gear wrench, or other suitable tool throughaccess window 17, it is also possible fortool rod 13 to be connected to a piston 40 (shown in phantom) housed withinbarrel 11. The piston 40 can be hydraulically/pneumatically driven in a matter well known to those skilled in the art, such that it drivestool rod 13 axially throughbarrel 11. Such hydraulically driven lubricators are well known to those skilled in the art and an example is shown in US 2012/0024521, incorporated herein by reference for all purposes.Lubricator 12 can haveconnections 19 which connect by hoses or the like to a source of pressure (not shown) to pressurize and release pressure from the lubricator in a manner well known to those skilled in the art. The pressurization oflubricator 12 can be accomplished hydraulically, pneumatically, electrically, or manually. It will be appreciated that the exact placement and configuration of the connections can vary. Additionally,lubricator 12 andconnections 19 can include, seals, valves, and control features not shown but which are well known to those skilled in the art. The pressure inlubricator 12 is shown bypressure gauge 21. - As depicted, the
elbow joint 14 is 90° but the exact angle of the joint can vary slightly, provided the tool is able to connect to the valve V. As depicted in the drawings,lubricator 12,tubular housing 16, andelbow joint 14 are separate pieces connected to one another byflange nuts 23, it will be understood that some or all of these components could be monolithically formed. - Turning to
FIGS. 3 and 4 , the details of thetool 10 can be seen. As noted, atubular housing 16 is connected betweenlubricator 12 andelbow joint 14. A threadedadapter flange 18 is connected bybolts 25 to the flange of a valve V of wellhead W. Aflexible steel cable 20 is extends through thetubular housing 16. A fitting 22 at the upper end ofcable 20 connectssteel cable 20 totool rod 13 oflubricator 12. Anadapter 24 at the other end ofcable 20 is releasably connected to aVR plug 50. In a preferred embodiment,centralizers 30 are spaced alongcable 20 to reduce friction and allow free rotation ofcable 20.Tubular housing 16 can vary in length depending on the size of the wellhead. - As shown in the figures, there are two valves through which the
VR plug 50 must travel.Tool 10 of the present invention can also be used on a wellhead with a single valve or more than two valves. Thus, while the description of the figures will be with respect to two valves, the invention is not so limited. - To install a
VR plug 50 in a wellhead W,tool 10 is lowered into cellar C and is connected to valve V1 byadapter flange 18 andbolts 25. Valves V1 and V2 are opened by turning handles H1 and H2, respectively. The pressure of the wellhead is determined by means well known to those skilled in the art, andlubricator 12 is pressurized by the pressure source (not shown) throughconnections 19 to equalize or match the pressure inlubricator 12,tubular housing 16 andelbow joint 14 with the pressure of the wellhead W. The pressurization of the lubricator is a process well known to those skilled in the art and will not be described in detail. The pressure within a wellhead can be anywhere in the range of from 0 psi to 10,000 psi. Even at 0 psi, a person of skill in the art would want to use the lubricator of the present invention as a safety precaution, e.g., in case of down hole plug failure. Matching the pressure with the pressure of the wellhead ensures that theVR plug 50 does not need to be driven against high pressure coming from the wellhead and makes VR plug installation easier and safer. Piston 40 inbarrel 11 is actuated to drivetool rod 13 downward. Alternatively, as described above,tool rod 13 can be driven downward manually with the use of a wrench or other gripping tool. The downward or axial driving oftool rod 13 in turn drivescable 20, and accordinglyVR plug 50, through valves V1 and V2. When theVR plug 50 is in position,tool rod 13 is rotated clockwise. This in turn rotatescable 20 and VR plug 50. As noted above, the wellhead and VR plug are threaded such that the rotation threadedly fixes VR plug 50 in position in wellheadW. Tool rod 13 can be rotated manually using a wrench to turn fitting 15 inaccess window 17 or by other means well known to those skilled in the art. Once VR plug 50 is installed,adapter 24 ofcable 20 is released fromVR plug 50 and the pressure ontool rod 13 is released to raisetool rod 13 back up (ortool rod 13 is raise back up manually) and accordingly pullcable 20 back intotubular housing 16. The pressure from thelubricator 12 can be bled off, again by a process well known to those skilled in the art.Tool 10 can then be disconnected from valve V1. - To extract the
VR plug 50,tool 10 is again lowered into cellar C and is connected to valve V1 byadapter flange 18 andbolts 25.Tool rod 13 is driven down by the actuation of piston 40 or manually, thereby drivingcable 20 through valves V1 and V2 untiladapter 24 connects withVR plug 50. The pressure in the wellhead is determined by means well known to those skilled in the art and the pressure inlubricator 12 is again equalized to the wellhead pressure onVR plug 50. This ensures that as soon as VR plug 50 is disconnected from the wellhead, the pressure from the wellhead does not send VR plug 50 shooting outwards.Tool rod 13 oflubricator 12 is rotated counterclockwise to unscrew VR plug 50 from wellheadW. Tool rod 13 is then retracted, either by releasing pressure on piston 40 or by manually retracting it. The retraction oftool rod 13 pullscable 20 and VR plug 50 out of the valves/wellhead. Once VR plug 50 is fully retracted, valves V1 and V2 are closed. The pressure inlubricator 12 can be released, andadapter flange 18 can then be disconnected from valve V1. - It will be understood by one of skill in the art, that the connection and release mechanism of
adapter 24 to and from VR plug 50 can vary. For example, the VR plug may have left hand threads on the end connectable to the adapter and right hand threads on the end to be connected in the wellhead. In such case, the VR plug is threadedly connected to the adapter. During installation, the clockwise rotation ofcable 20 threads the VR plug into the wellhead. Once the VR plug is fully in place, further clockwise rotation ofcable 20 unthreads theadapter 24 fromVR plug 50. Likewise, when extracting the VR plug, counterclockwise rotation willthread adapter 24 ontoVR plug 50 and once it is connected, further counterclockwise rotation will unthread VR plug 50 from the wellhead. This is simply one method of connecting and releasingadapter 24 fromVR plug 50. There are other means of releasably connectingadapter 24 to VR plug 50 that are well known to those skilled in the art. - It will further be understood by those skilled in the art that depending on the type of wire used in the tool, that it may be necessary to have two versions of
tool 10, namely, a left hand version and a right hand version. Steel cables are often formed of smaller braided or twisted wires. These braided wires can only be rotated one direction, as rotating the opposite direction would unbraid or untwist the wires. Apart from the direction of the wire braid and thus the permissible direction of rotation, all other features would be the same between the left hand and right hand versions oftool 10. Alternatively,cable 20 could be formed from anti-twisting steel rope or coated with a flexible coating which prevents wire separation. In such a case, a single version oftool 10 could accomplish both installation and extraction of a VR plug. - The present invention provides multiple advantages over the prior art. It allows for the installation of VR plugs in narrow cellars or other difficult to reach areas. It eliminates the need for digging out trenches and work spaces in cellars, thus saving time and money. Workers can operate the tool from ground level. It thus improves safety by allowing workers to operate at a distance from the valves.
- Although specific embodiments of the invention have been described herein in some detail, this has been done solely for the purposes of explaining the various aspects of the invention, and is not intended to limit the scope of the invention as defined in the claims which follow. Those skilled in the art will understand that the embodiment shown and described is exemplary, and various other substitutions, alterations and modifications, including but not limited to those design alternatives specifically discussed herein, may be made in the practice of the invention without departing from its scope.
