Description

ROTATING ASSEMBLY FOR ALIGNMENT OF STRING TOOLS
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Application No. 15/344166, filed on November 4, 2016, which is incorporated herein by reference in its entirety.
BACKGROUND
[0002] In the drilling and completion industry, running strings having various components that require alignment with one another in order to properly connect with one another, communicate, convey fluid, etc. is an extremely common occurrence. Alignment of such components has invariably required timing of threads in adjacent tubulars forming the base string. The method has been perfected over many decades and works exceptionally well for aligning components needing such treatment but it also increases cost in manufacture, increases time in running the string, etc. With increasing complexity of strings being run, the requirements for alignment are not likely to ebb. The art would therefore be quite receptive to alternate methods for aligning components on adjacent joints without resorting to the timing of threads.
SUMMARY
[0003] A rotating assembly for alignment of tool strings including a tubing joint, and a component mounted to the tubing joint, the component being axial movement restricted and rotatable on the joint.
[0004] A method for running in a borehole a string with components thereon that require alignment including a threading adjacent joints of tubing together, the joints having components thereon, rotating the components to align with each other, and connecting the components operably to one another.
[0005] A downhole system including a string, and a plurality of components that require alignment with one another, the components axially immovably and rotatably movably mounted to the string.

[0008] FIG. 2 is a perspective view of the two adjacent joints of FIG. 1 with components thereon having been aligned;
[0009] FIG. 3 is the view of FIG. 2 but with a leakoff tube connecting the two aligned components;
[0010] FIG. 4 is the view of FIG. 3 but with jumper tubes and connectors illustrated;
[0011] FIG. 5 illustrates end rings of the embodiment of FIG. 1;
[0012] FIG. 6 is a cross sectional view of one end of one of the components to illustrate stopper rings; and
[0013] FIG. 7 is an alternate axial capture arrangement using a single stopper ring.
DETAILED DESCRIPTION
[0014] A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.
[0015] Referring to FIG. 1, two joints 10 and 12 of a tubing string 14 are coupled together with a coupling 16. A component 18 is disposed upon one of the joints and a component 20 on the other. While the components illustrated are shunt tube assemblies, the disclosure is not intended to be limited only to such assemblies but to any assembly that would require alignment including any ancillary fluid conveying tubular assemblies that form an extended fluid conveyance, communication lines that require alignment, etc. As illustrated, the components 18 and 20 each comprise a shroud 22, two shunt tubes 24 and 26, a leak off tube 28 and an end ring 30 and 32. While only one end ring is illustrated for each component, it is contemplated in some embodiments that an end ring 30 and 32 may be located on each end of such components. Rings 30 and or 32, in the illustrated embodiment have recesses 34, 36 and 38, respectively, for passage of the shunt tubes 24 and 26 and the leak off tube 28. The recesses are labeled in FIG. 5.
[0016] In each case, the components 18 or 20 are disposed over ajoint 10 or 12 at a manufacturing location and then restricted in axial movement in that position by stopper rings 40 that are most easily seen in FIG. 6. Stopper rings 40 may be continuous or discontinuous members that are proud of the surface of each joint and are located on an end of a component. Stopper rings 40 are secured to the joint 10 or 12 by securement means such as welding, interference fit, snap ring in a groove, etc. Stopper rings 40 on both axial ends of a component 18 or 20 easily ensure axial restriction while allowing rotational movement.
Alternatively, a single stopper ring 40 may be used if a component cannot otherwise move axially on a joint for other structural reason or if the stopper ring 40 itself is captured such as by securing a capture ring 42 (continuous or discontinuous) to end ring 30 with securement 44 such as fasteners, weld, etc.as shown in FIG. 7.
[0017] In any event, with the components secured axially but allowed to rotate on their respective joints 10 and 12, the joints 10 and 12 may be secured together by threaded connection, which may be a coupling 16 as shown or a pin and box connection, without regard for timing of threads. Making up the joints then is a rapid and conventional affair. The string and components will then appear as in FIG. 1. At this point, the components 18 and 20 may be rotated on the joints 10 and 12 respectively until the components are aligned. In this case, alignment is related to the shunt tubes 24 and 26 and leak off tube 28 of each of component 18 and 20. Once aligned, as shown in FIG. 2, connection hardware can be engaged with these components to create a fluid pathway. Connection hardware for the illustrated embodiment includes illustrated shunt tube jumpers 50 and 52 and leakoff jumper 54. Not illustrated but which will be appreciated as a part of the connection hardware to one of ordinary skill is another shroud to protect the jumper tubes. The shroud (not shown) that may be installed contemporaneously with the jumper tubes or shortly thereafter to protect the same for the trip downhole. A commercial embodiment of connection hardware is available from Baker Hughes Incorporated identifiable by Direct Pak Screen, product number H48654.
[0018] FIG. 3 illustrates the string 14 after the leakoff tube jumper 54 is installed and FIG. 4 illustrates the string 14 after the shunt tube jumpers 50 and 52 are added. These are all connected to shunt tubes and leak off tubes by individual connectors 56 and 58 for example, in one embodiment.
[0019] A method for running in a borehole a string with components thereon that require alignment includes, threading adjacent joints together having components thereon; rotating the components to align with each other; and connecting the components operably to one another. In some embodiments connecting the components to one another includes the addition of connection hardware while in other embodiments, the components may be connected together directly.
[0020] Further contemplated herein is a downhole system comprising a string; and a plurality of components that require alignment with one another, the components axially immovably and rotatably movably mounted to the string. The system includes one or more stop rings to restrict axial movement of components. As illustrated the system also includes screens 60 (best seen in FIG. 6) that are operationally cooperative with the components, which are shunt tube assemblies to perform a gravel packing operation.
