9CIaimSDI-aWingFigures APPARATUS FOR INSTALLING OR REMOVING A FLOW CONTROL DEVICE FROM A WELL TUBING BACKGROUND OF THE INVENTION Generally, it is old to provide a mandrel having a sidepocket for receiving a flow control device such as a gas lift valve which is installed and removed through an orienting sleeve in the mandrel by a kickover tool. However, kickover tools are generally lengthy in design which is undesirable in certain applications.
The present invention is directed to an improved mandrel and improved running and orienting tool which may be relatively short in length and does not require a kickover tool but in which a flow control device can be positively installed in a selected mandrel in a well tubing.
SUMMARY The present invention is directed to a mandrel and an orienting tool for installing and removing flow control devices from a pocket in the mandrel. The mandrel pocket is positioned directly below the tubing connection at the top of the mandrel. The mandrel includes a bore extending between the ends of the mandrel and includes an offset portion from the pocket and the tubing connection to the well tubing at the bottom of the mandrel is in alignment with the offset bore portion. Orienting means are provided in the mandrel above the pocket for orienting an orienting running tool out of alignment with the pocket on downward movement through the mandrel but orienting the orienting running tool into alignment with the pocket on upward movement through the mandrel.
The present invention is further directed to a mandrel having a two-way orienting sleeve having a first upwardly directed guide surface extending downwardly and a deflecting shoulder below the lower end of the first guide surface for orienting a running tool out of alignment with the mandrel pocket on downward movement, and a second downwardly directed guide surface extending upwardly and positioned below the first guide surface with a stop shoulder above the top of the second guide surface for engaging and orientating a running tool into alignment with the mandrel pocket.
Yet a further object is the provision of an orienting and running apparatus for coacting with the mandrel for installing and removing a flow control device from the mandrel pocket which includes two radially locating fingers, one with a shoulder facing downwardly which coacts with the first guide surface for orienting the running apparatus and flow control device supporting assembly out of alignment with the pocket to allow the orienting tool to pass through the mandrel, and a second finger having a shoulder facing upwardly which engages the second guide surface and stop shoulder to place the tool and flow control handling assembly in alignment with the pocket allowing the setting or pulling operation to be completed. A flow control device supporting member is connected to the running tool body at a point off of the longitudinal axis of the body for moving the flow control device into and out of alignment with the mandrel pocket as the orientation tool is rotated.
Yet a still further object of thc present invention is the provision of an orientation or running tool for installing or removing a flow control device from a mandrel pocket in which the first locating finger is pivotally connected to the body adjacent the upper end of the finger with first spring means urging the first finger outwardly from the body and the body having a tapered upper edge for pivoting by obstructions while moving freely upwardly through the well bore. The second locating finger is pivotally connected to the body adjacent the lower end of the finger and includes a second spring means urging the second body outwardly and having a tapered lower edge for pivoting by obstructions and moving freely downwardly through the well tubing.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, and particularly to FIGS. 1A and 1B, the present invention is generally indicated by the reference numeral 10 and generally includes a mandrel 12 and an orienting and running tool 14.
The mandrel 12 includes the usual means for connection in a well tubing 16 such as a threaded box 18 at the top of the mandrel and a threaded box 20 at the bottom of the mandrel 12.
The mandrel 12 includes a sidepocket 22 and a bore 24 extending between the tubing connections 18 and 20 for passage of well tools through the mandrel 12. However, it is to be noted that the pocket 22 is positioned directly below the tubing connection 18 in the upper portion of the bore 24 although preferably not coaxial therewith. However, as will be seen, the pocket 22 is in sufficient alignment with the upper portion of the bore to allow the installation and removal of flow control devices 26, such as a gas lift valve, from the pocket 22 without requiring a lengthy kickover tool having pivoted connections for transversely shifting a valve from the mandrel bore to an offset sidepocket.
The sidepocket 22 may also include a guide means 28 for preventing other well tools passing through the bore 24 from catching on the sidepocket and is sized to allow only flow control devices 26, such as a gas lift valve, to engage the sidepocket 22. Deflector 30 directs other well tools into the bore 24, all as more fully described in copending patent application Ser. No.
As best seen in FIGS. 1A and 2, the orientation sleeve 32 generally includes a first guide surface 34 providing an upwardly directed surface for engaging the downwardly moving tool 14. The guide surface 34 is preferably helical and extends downwardly. A slot 36 may be provided leading from the bottom of the first guide surface 34 and terminates in a deflecting shoulder 38. A second guide surface 40 is provided below the first guide surface 34. The second guide surface 40 is preferably helical and extends upwardly and a stop shoulder 42 is positioned above the top of the second guide surface for engaging and guiding the orientation tool 14 to position the flow control device 26 over the pocket 22 for installing or removing a flow control device 26.
Referring to FIGS. 1A and 2, the orientation or running too] 14 may include a first body 56 and a second body 58 telescopically movable in the body 56. Spring means 62 is provided between the body 56 and 58 for yieldably urging the body 58 upwardly. A suitable connector 60 is provided connected to the body 58 such as a threaded connection whereby the tool 14 may be moved in the well tubing 16 and one or more mandrels 12 by any suitable means such as a wireline or a hydraulic pump in assembly, both of which are conventional and no further description need be made.
A flow control handling device 80 is provided connected to the body 56 of the running tool 14 for supporting the flow control device 26 for installing the flow control device 26 in the sidepocket 26 or for supporting a retrieving mechanism (not shown) for removing the flow control device 26 from the sidepocket 22. It is to be noted that the axis of the handling apparatus 80 is connected to the body 56 at a point off of the longitudinal axis of the body 56. This eccentric connection allows the running tool 14 to be rotated in one direction for bypassing the pocket 22 in a particular mandrel l2 and moving down the well tubing 16 to other mandrels 12 for selectively installing or removing flow control devices 26 in the desired mandrel 12. When the desired mandrel 12 is reached, the running tool 14 may be rotated to rotate the eccentric connection 80 into alignment with the desired sidepocket 22 for installing or removing a flow control device 26.
The running tool 14 includes two radially extending locating fingers 64 and 66. Locating finger 64 is connected to the body 56 by a pin 68 adjacent the upper end of the finger 64 and a spring 70 is provided yieldably urging the finger 64 radially outward whereby a downwardly directed shoulder 72 on the finger 64 may engage the upwardly directed guide surface 34 and then enter the slot 36 for rotating the running tool 14 to move the eccentric handling device 80 and flow control device 26, as best seen in FIG. 2, out of alignment with the well pocket 22.
Thus as the running tool 14 is moved down the tubing 16 and through the oricntating sleeve 34, the shoulder 72 on finger 64 contacts the upwardly directed guide surface 34 and rotates the running tool 14 to move the eccentric handling apparatus 80 out of alignment with the pocket 22. As the running tool 14 is further moved down the orienting sleeve 32, the first locater finger 64 engages a deflecting shoulder 38 and moves inwardly allowing the running tool 14 to readily pass downward through the orienting sleeve 32 and the mandrel 12 without becoming aligned with the pocket 22. As best seen in FIG. 2, the end of the flow control device 26, is outside the sidepocket 22 and passes by the pocket 22 and the deflector 30 will engage the remainder of the running tool 14 and directs tool 14 into the offset portion 24 of the mandrel bore. It is also noted that the first locater finger 54 includes a tapered upper edge 74 so that the first locater finger may readily bypass obstructions in the well tubing 16 and mandrel 12 as the running tool 14 is moved upwardly in the well tubing.
The second locating finger 66 is pivotally connected to the body 58 by a pin 82 and is yieldably urged radially outward by a spring 84. The locating finger 66 includes a tapered lower edge 86 whereby the finger 66 may readily pivot by obstructions in the well tubing and the mandrel 12 as the tool 14 is carried downwardly in a well tubing. However, the locating finger 66 includes an upwardly directed shoulder 88, which, when the running tool 14 is moved upwardly through the desired mandrel 12, will contact the downwardly directed guide surface 42 to rotate the running tool 14, as best seen in FIG. 1A, thereby rotating the eccentric handling apparatus into position over the pocket 22. As the locater finger 66 reaches the uppermost portion of theguide surface 40 it contacts the stop shoulder 42 to indicate that the well control device 26 is aligned over the pocket 22.
When the locater finger 66 contacts and engages the stop shoulder 42, the running tool 14 may then be lowered for installing or removing a flow control device 26 from the pocket 22. Of course, as the running tool 14 is being removed from the well tubing after performing its operation. the finger 66 will again contact the shoulder 42. A sufficient upward movement on the outer body 56 will longitudinally move body 56 relative to the internal body 58 and overcome the spring 62 so that a retracting shoulder 90 on the outer body 56 will contact the tapered surface 56 on the locater finger 66 and retract finger 66 away from the stop shoulder 42,
Thus, flow control devices may be installed in a well tubing on a relatively short running tool 14, which is particularly useful in hydraulic pump operations, although the present invention is equally applicable to wireline service, and the running tool 14 will actively and positively align the handling connection 80 over the well pocket 22 for installation and for removing a flow control device 26 from the well pocket 22. The running tool 14 may be run down the well tubing 16 and the upper locating finger 64 will contact the upwardly directed guide surface 34 ofeach mandrel 12 to rotate the running tool 14 and move the control device 26 out of alignment with the seat 22. The running tool 14 may be continued to be moved downward through the mandrel 12 and the well bore 16 to be set in any selected mandrel 12. When the running tool 14 reaches the selected mandrel and passes through the orientation sleeve 32, it is then raised whereby the lower locater finger 66 may contact the downwardly directed guide surface 40 and come into engagement with the stop shoulder 42 at which time the eccentric handling apparatus 80 and flow control device 26 or tool pulling device is aligned with the pocket 22. The running tool 14 may be lowered to perform the desired operation.
The present invention therefore, is well adapted to carry out the objects and attain the ends and advantages mentioned as well as others inherent therein. While a presently preferred embodiment of the invention is given for the purpose of disclosure, numerous changes in the details of construction and arrangement of parts will readily suggest themselves to those skilled in the art and which are encompassed within the spirit of the invention and the scope of the appended claims.
