Definitions
- the present disclosure relates generally to coiling a continuous rod.
- Some artificial lift systems may apply a rod string inside a production string for hydrocarbon production.
- the rod string may be assembled from rod joints connected by collars, or may be a continuous rod.
- a continuous rod may be connected by collars with a polish rod or other uphole equipment, and with a shear rod or other downhole pump equipment, but may otherwise lack collars along the majority of the length of the rod string.
- a continuous rod may provide advantages over a jointed rod string when producing heavy oil, when producing from a sandy formation, or in other circumstances where frequent servicing is common or clearance inside the production string is otherwise of high value.
- a continuous rod may be transported to a well site on a transport reel to be run into the well inside the production string.
- the continuous rod may be connected with a shear rod or any applicable downhole pump equipment, and run downhole. As the continuous rod is run into the well, it is uncoiled from the transport reel.
- the continuous rod may be connected with a polish rod or other uphole production equipment once the continuous rod is in a production position in the production string.
- the continuous rod may be coiled from the transport reel to a service reel, and from the service reel into the well.
- the rod string may be pulled from the well and coiled onto a service reel as the rod string emerges from the well.
- the continuous rod coils onto the service reel while being pulled from the well as the service reel is rotated.
- the continuous rod may be temporarily stored on the service reel until the continuous rod is to be run back into the well.
- the continuous rod may be transported offsite while wound on the service reel.
- Pulling a continuous rod from a well may be accompanied by coiling the continuous rod onto a service reel as the continuous rod emerges from a rod guide.
- an uphole end of the continuous rod may be secured onto the service reel and the service reel rotated to coil the continuous rod along a radial rod pocket defined between a pair of guide pins or other guide members on the service reel during rotation of the reel.
- the continuous rod is coiled along the rod pocket between the pair of guide pins and other pairs of guide pins located radially around the service reel.
- the continuous rod is typically tied to one of the guide pins or a different portion of the service reel with haywire to secure the continuous rod to the service reel.
- Previous approaches to securing the continuous rod to the service reel may be time-consuming. Previous approaches to securing the continuous rod to the service reel may be inconsistent in terms of where the continuous rod is secured in relation to the guide pins, in terms of the strength of the connection between the continuous rod and the service reel, or both. Previous approaches to securing the continuous rod to the service reel may be unreliable and injury to personnel, damage to equipment, lost time, or other losses may result from the haywire coming undone and the uphole end of the continuous rod potentially snapping out from between the guide pins as a result of torsion stored in the continuous rod. It is, therefore, desirable to provide an improved approach to securing a continuous rod to a reel prior to coiling the continuous rod on the service reel.
- a coupling for securing the continuous rod to a reel.
- the coupling includes a threaded box for threadedly connecting with an uphole pin end of a continuous rod.
- the coupling also includes a connector for securing the coupling to the reel. The connector may be secured to the reel at a connection point on the reel.
- the connector may include any common connection mechanism amenable to use with the connection point on a given reel.
- a coupling may be designed for use with a reel having an open connection point, such as an outside guide pin defining the rod pocket on a collapsible service reel.
- Such a coupling may include a ring or other closed connector for securing the coupling to the outside guide pin. Securing the coupling to the outside guide pin provides a simple and reliable connection between the continuous rod and the service reel, and locates the uphole pin end of the rod at a consistent position with respect to the outside guide pin.
- the ring may be placed over any load bearing connection point (e.g. a pin, a hook, etc.) to secure the continuous rod to the reel.
- a coupling designed for securing to a ring or other closed connection point on the reel may include a hook or other open connector rather than a ring or other closed connector.
- the hook may include a cover to close off the hook once the connection is established.
- An open connector may also be applied to an open connection point on the reel.
- the threaded box of the coupling may be threadedly engaged with the uphole pin end of the continuous rod and the connector may be secured to the reel.
- the connector may be secured to the reel with the continuous rod located between any guide pins on the service reel for guiding the continuous rod along the radial rod pocket during coiling.
- the connector may be secured to the reel by any suitable approach depending on the specific connection being made between the connector and the reel, such as by the example open and closed connectors as described above in relation to the coupling.
- the present disclosure provides a coupling for use with a continuous rod and a reel, and a method of using the coupling to coil a continuous rod on the reel.
- the coupling includes a threaded box portion for threadedly connecting with an uphole pin end of the continuous rod.
- the coupling includes a connector for securing the coupling to the reel. Once secured to the reel by the coupling, the continuous rod can be coiled around the reel by rotation of the reel.

Abstract
Description
- This application claims the benefit of priority of U.S. provisional patent application No. 62/320,255, filed Apr. 8, 2016, the contents of which are incorporated herein by reference.
- The present disclosure relates generally to coiling a continuous rod.
- Some artificial lift systems may apply a rod string inside a production string for hydrocarbon production. The rod string may be assembled from rod joints connected by collars, or may be a continuous rod. A continuous rod may be connected by collars with a polish rod or other uphole equipment, and with a shear rod or other downhole pump equipment, but may otherwise lack collars along the majority of the length of the rod string. A continuous rod may provide advantages over a jointed rod string when producing heavy oil, when producing from a sandy formation, or in other circumstances where frequent servicing is common or clearance inside the production string is otherwise of high value.
- A continuous rod may be transported to a well site on a transport reel to be run into the well inside the production string. The continuous rod may be connected with a shear rod or any applicable downhole pump equipment, and run downhole. As the continuous rod is run into the well, it is uncoiled from the transport reel. The continuous rod may be connected with a polish rod or other uphole production equipment once the continuous rod is in a production position in the production string. Alternatively, the continuous rod may be coiled from the transport reel to a service reel, and from the service reel into the well.
- During servicing, workover, shut in, or other activity that requires the rod string to be pulled from the well, the rod string may be pulled from the well and coiled onto a service reel as the rod string emerges from the well. The continuous rod coils onto the service reel while being pulled from the well as the service reel is rotated. The continuous rod may be temporarily stored on the service reel until the continuous rod is to be run back into the well. Following shut in or in any situation where the continuous rod no longer needed at the well, the continuous rod may be transported offsite while wound on the service reel.
- Pulling a continuous rod from a well may be accompanied by coiling the continuous rod onto a service reel as the continuous rod emerges from a rod guide. To coil the continuous rod onto the service reel, an uphole end of the continuous rod may be secured onto the service reel and the service reel rotated to coil the continuous rod along a radial rod pocket defined between a pair of guide pins or other guide members on the service reel during rotation of the reel. As the service reel is rotated, the continuous rod is coiled along the rod pocket between the pair of guide pins and other pairs of guide pins located radially around the service reel. The continuous rod is typically tied to one of the guide pins or a different portion of the service reel with haywire to secure the continuous rod to the service reel.
- Previous approaches to securing the continuous rod to the service reel may be time-consuming. Previous approaches to securing the continuous rod to the service reel may be inconsistent in terms of where the continuous rod is secured in relation to the guide pins, in terms of the strength of the connection between the continuous rod and the service reel, or both. Previous approaches to securing the continuous rod to the service reel may be unreliable and injury to personnel, damage to equipment, lost time, or other losses may result from the haywire coming undone and the uphole end of the continuous rod potentially snapping out from between the guide pins as a result of torsion stored in the continuous rod. It is, therefore, desirable to provide an improved approach to securing a continuous rod to a reel prior to coiling the continuous rod on the service reel.
- It is an object of the present disclosure to obviate or mitigate at least one disadvantage of previous approaches to coiling a continuous rod, such as use of haywire to secure the continuous rod to a reel. Generally, a coupling is provided for securing the continuous rod to a reel. The coupling includes a threaded box for threadedly connecting with an uphole pin end of a continuous rod. The coupling also includes a connector for securing the coupling to the reel. The connector may be secured to the reel at a connection point on the reel.
- The connector may include any common connection mechanism amenable to use with the connection point on a given reel. For example, a coupling may be designed for use with a reel having an open connection point, such as an outside guide pin defining the rod pocket on a collapsible service reel. Such a coupling may include a ring or other closed connector for securing the coupling to the outside guide pin. Securing the coupling to the outside guide pin provides a simple and reliable connection between the continuous rod and the service reel, and locates the uphole pin end of the rod at a consistent position with respect to the outside guide pin. Similarly, the ring may be placed over any load bearing connection point (e.g. a pin, a hook, etc.) to secure the continuous rod to the reel. In another example, a coupling designed for securing to a ring or other closed connection point on the reel may include a hook or other open connector rather than a ring or other closed connector. The hook may include a cover to close off the hook once the connection is established. An open connector may also be applied to an open connection point on the reel.
- In use, the threaded box of the coupling may be threadedly engaged with the uphole pin end of the continuous rod and the connector may be secured to the reel. The connector may be secured to the reel with the continuous rod located between any guide pins on the service reel for guiding the continuous rod along the radial rod pocket during coiling. The connector may be secured to the reel by any suitable approach depending on the specific connection being made between the connector and the reel, such as by the example open and closed connectors as described above in relation to the coupling. Once the threaded box is threadedly engaged with the pin end of the continuous rod and the connector is secured to the reel, the reel may be rotated, pulling the continuous rod with rotation of the reel and coiling the continuous rod onto the reel while securely connected with the reel by the coupling. The coupling provides a consistent and reliable connection between the continuous rod and the reel.
- In a first aspect, the present disclosure provides a coupling for use with a continuous rod and a reel, and a method of using the coupling to coil a continuous rod on the reel. The coupling includes a threaded box portion for threadedly connecting with an uphole pin end of the continuous rod. The coupling includes a connector for securing the coupling to the reel. Once secured to the reel by the coupling, the continuous rod can be coiled around the reel by rotation of the reel. In an example application, the connector may include a ring for securing the coupling to an outside guide pin of a collapsible service reel.
- In a further aspect, the present disclosure provides a method of coiling a continuous rod onto a reel. The method includes threadedly connecting a coupling to an uphole pin end of the continuous rod; securing the coupling to the reel; and rotating the reel to coil the continuous rod onto the reel.

A coupling may be used to couple the continuous rod with the reel. The coupling includes a threaded box and a connector. The threaded box may be threaded to match American Petroleum Institute (“API”) thread for continuous rod pin ends for connection to a pin end of a continuous rod. The connector may include a ring, a hook, or any suitable feature for use with a connection point on a particular reel that the connector is designed to be used with.
- The coupling described herein may include a connector with features for connection with an open connection point on the reel, a closed connection point on the reel, or both. Examples of an open connection point include a load-bearing pin or a hook. A connector on the coupling including a ring with a sufficient inside diameter to receive the load-bearing pin or hook may be engaged around the load-bearing pin or hook to connect with the load-bearing pin and secure a continuous rod (threaded into the threaded box of the coupling) to the reel.
- Examples of closed connection points include a ring, or a load-bearing pin capped by a portion of the pin too large to be received by a ring connector. A hook or other open connector with a sufficiently large open portion to receive the outside diameter of the ring or of the pin below the large portion may be engaged with either of the example closed connection points to secure a continuous rod (threaded into the threaded box of the coupling) to the reel. A connector including a hook or other suitable feature for connecting with a closed connection point may also be connected with an open connection point, and such use may be facilitated where the connector includes a cover to close the open portion of the hook or other feature.
- A collapsible service reel may include inside and outside guide pins for defining a radial rod pocket. Each of the outside guide pins may provide an open connection point on the collapsible service reel in designs with no large feature on top of the outside guide pins. An example of a collapsible service reel is shown in photographs included in an advertisement for the COROD® Reel Mover. The advertisement is copyright 2014, has a footer with reference number 11138.00, and is available online at www.weatherford.com.
- Other continuous rod reels, such as a transport reel, may be more enclosed than a service reel to secure a continuous rod to the transport reel for transport while being maintained on an angle, such as the transport reel disclosed as prior art in
FIGS. 1 A and 1B of U.S. Pat. No. 8,869,580 to Basler et al. - To apply the apparatus and method described herein to previous continuous rod reels lacking an inherent connection point, such as the connection point provided by an outside guide pin of a service reel, an open connection point or a closed connection point may be added to the reel for use with the connectors described herein. An example of such a connection point is provided in the
connection ring 135 ofFIGS. 9, 11, and 12 below. -

Each of thearms 14 may include abrace 19 extending from thecentral body 12 to a position intermediateinside end 13 and theoutside end 15. The position where thebrace 19 connects with thearm 14 may correspond to theinside guide pin 18, as shown in theservice reel 10. A plurality ofstabilizer members 17 may extend between thebrace 19 and thearm 14. The outside guide pins 16 and the inside guide pins 18 of theservice reel 10 are examples of guide members that may be on a continuous rod reel. - The
continuous rod 20 is shown emerging from arod guide 22. Thecontinuous rod 20 includes a threaded pin end 24 on an uphole end of thecontinuous rod 20. The threaded pin end 24 may be used to threadedly connect thecontinuous rod 20 to a polish rod (not shown) or other uphole production equipment (not shown) when thecontinuous rod 20 is being used for production. The threaded pin end 24 may be threaded with standardized thread patterns and sizes defined by the API, as shown in Table 1. -
TABLE 1 API standard continuous rod outside diameters and thread sizes on the pin end Continuous Rod OD API Thread Sizes ⅞″ ⅞″ 1″ ⅞″, 1″, 1⅛″ 1⅛″ 1″, 1⅛″ - The continuous rod outside diameter and thread sizes shown in Table 1 are the current commonly-used API standardized threads and OD values for a continuous rod. The approach to coiling a continuous rod described herein may be applied to any specific OD or thread size of a given continuous rod that the apparatus and method may be applied to.
- The outside guide pins 16 positioned on each
arm 14 define an outsideradial path 25. When theservice reel 10 is rotated, the guide pins 16 follow the outsideradial path 25. The inside guide pins 18 positioned on eacharm 14 similarly define and follow an insideradial path 27. Acontinuous rod path 26, also referred to as a rod pocket, is defined between the outsideradial path 25 and the insideradial path 27. When thecontinuous rod 20 is secured to theservice reel 10 by previous methods, such as tying thecontinuous rod 20 to one of thearms 14 with haywire, thecontinuous rod 20 may follow thecontinuous rod path 26 while coiling as a result of rotation of theservice reel 10. -
FIG. 3 shows acoupling 50 for securing a continuous rod to a reel, such as securing thecontinuous rod 20 to theservice reel 10. Thecoupling 50 includes abody 52 extending between afirst end 51 and asecond end 53. A threadedbox 54 is defined in thebody 52 proximate thefirst end 51 for threading on to the pin end 24. Aconnector 60 is located proximate thesecond end 53 of thebody 52. Theconnector 60 includes aring 62 extending from thebody 52. Thering 62 may extend from thebody 52 in a fixed relationship with thebody 52 as shown. -
FIGS. 4 and 5 show thecoupling 50 threaded on to thecontinuous rod 20 at the threadedbox 54 and with theconnector 60 secured to theservice reel 10 at theoutside guide pin 16. Thering 62 may be placed over theoutside guide pin 16 and lowered to thearm 14 as shown. The pin end 24 of thecontinuous rod 20 is threadedly connected with and inside the threadedbox 54, and is not shown inFIGS. 4 and 5 . -
FIG. 6 shows a plan view of thecoupling 50 securing thecontinuous rod 20 to theservice reel 10 for coiling thecontinuous rod 20 around theservice reel 10. -
FIG. 7 shows thecoupling 50, thecontinuous rod 20, and theservice reel 10, after rotating theservice reel 10 about thecentral body 12 through about 270 degrees relative to the position shown inFIG. 6 . As theservice reel 10 is rotated about thecentral body 12, thecontinuous rod 20 is coiled around theservice reel 10. - As shown in
FIGS. 6 and 7 , thecoupling 50 may be threaded on to thecontinuous rod 20 by threading the pin end 24 of thecontinuous rod 20 into the threadedbox 54. Thecoupling 50 is secured to theservice reel 10 by engaging thering 62 with one of the outside guide pins 16. Thering 62 is passed onto and over theoutside guide pin 16, and lowered to a position on theoutside guide pin 16 proximate thearm 14. Threading thecontinuous rod 20 into the threadedbox 54 and connecting theconnector 60 with theservice reel 10 may provide a predictable and secure connection between thecontinuous rod 20 and theservice reel 10. The predictability may include predictability both in the strength of the connection and in the location of the connection relative to the outside guide pins 16 and other features of theservice reel 10. -
FIGS. 8 and 9 show plan and elevation schematics of an alternative design of areel 110 for coiling thecontinuous rod 120. Thereel 110 includes many features similar to a transport reel. Thereel 110 includes thecentral body 112 and the plurality ofarms 114, with each of thearms 114 extending outward from theinside end 113 proximate thecentral body 112 to theoutside end 115 opposed from theinside end 113. - Unlike the
service reel 10, thereel 110 lacks outside guide pins that each provide an inherent connection point. Each of thearms 114 ends includes abar 130 extending between abottom end 132 and atop end 134. On each of thebars 130, thebottom end 130 extends from thearm 114 proximate theoutside end 115. Each of thebars 130 includes anangled portion 137 intermediate thebottom end 132 and thetop end 134. Theangled portion 137 defines anangle 136 for containing thecontinuous rod 120 when coiled around the reel 110 (continuous rod 120 not shown coiled around the reel 110). Aconnection ring 135 is included on each of thebars 130 proximate theangled portion 137. Theconnection ring 135 is an example of a closed connection point on thereel 110. Other closed connection points, or open connection points, may be applied in place of theconnection ring 135. - An
intermediate ring 131 may be positioned intermediate thebottom end 132 and thetop end 134 of each of thebars 130. Theintermediate ring 131 may be positioned at theangled portion 137 of thebar 130. Anupper ring 138 may be positioned proximate the respective top ends 134 of each of thebars 130. - In the
reel 110, the outsideradial path 125 may be defined by thebars 130 at the apex of theangled portions 137. As a result, the outsideradial path 125 may coincide with the radial path defined by rotation of theintermediate ring 131. When thereel 110 is rotated, thebars 130 follow the outsideradial path 125 at theangled portion 137. The inside guide pins 118 positioned on eacharm 114 similarly define and follow the insideradial path 127. Thecontinuous rod path 126 is defined between the outside radial path 125 (corresponding to the intermediate ring 131), and the inside radial path 127 (corresponding to a path through which the inside guide pins 118 rotate). - In previous transport reels, when the continuous rod is secured to the transport reel by welding, haywire, or other previous methods and coiled around the transport reel by rotation, the continuous rod may follow a continuous rod path similar to the
continuous rod path 126. When preparing a transport reel loaded with a continuous rod at a fabrication plant or other source location, the continuous rod may be welded to the transport reel and may lack threaded pin ends. In such cases, the pin ends may be welded to the continuous rod at the wellsite before running the rod downhole. In other cases, a transport reel may be loaded with a continuous rod having a pin end at a fabrication plant or other source location, or a transport reel may loaded with a continuous rod at a well site to remove the continuous rod from the well site. However, embodiments described herein related to thereel 110 and theconnection point 135 may be applicable to a transport reel, or to a service reel (including a collapsible a service reel) with a connection point that is not present inherently as part of the reel design (such as theguide pin 16 on the service reel 10), with a connection point that is a closed connection point, or both. -
FIG. 10 shows acoupling 150 for use with a closed connection point, such as thering 135 on thereel 110. Thecoupling 150 includes thebody 152 extending between thefirst end 151 and thesecond end 153. A threadedbox 154 is defined proximate thefirst end 151 for threading on to thepin end 124. Theconnector 160 includes ahook 164. Thehook 164 may be connected to thereel 110 at theconnection ring 135 for securing thecontinuous rod 120 to thereel 110. -
FIGS. 11 and 12 show thecoupling 150 threaded on to acontinuous rod 120 and connected with thereel 110 at theconnection ring 135 for securing thecontinuous rod 120 to thereel 110. Theconnection ring 135 may be included with thereel 110 to provide a connection point for a reel lacking an inherent connection point, such as the outside guide pins 16 on theservice reel 10. As above, theconnection ring 135 is an example of a closed connection point on thereel 110. Other closed connection points, or open connection points, may be applied in place of theconnection ring 135. A coupling with a closed connector, such as thering 62 of theconnector 60, may be applied to an open connection point on the reel. A coupling with an open connector, such as thehook 164 of theconnector 160, may be applied to either a closed connection point or an open connection point on the reel. - In the
reel 110, thetop ring 136 closes off the top ends 134 of thebars 130 and prevents a closed connector, such as theconnector 60 with thering 62, from securing thecontinuous rod 120 to the closed-top reel 110 by placing the closed connector over thetop end 134 of the one of thebars 130. This is in contrast to use of thecoupling 50 with the to theservice reel 10, in which theoutside guide pin 16 of theservice reel 10 may be received within thering 62, providing an inherent open connection point with theservice reel 10 for theconnector 60, as shown inFIGS. 4 to 7 . In addition, thebar 130 may be relatively large, which in transport reels may be in part to secure heavy loads of coiled continuous rod during transport. As a result, even absent thetop ring 136, thereel 110 may lack an inherent connection point. - The
connection ring 135 facilitates use of thecoupling 150 with thereel 110. Where thereel 110 is a transport reel, theconnection ring 135 may be included in the transport reel to allow coiling of continuous rod on to the transport reel prior to transport with the advantages of using thecoupling 150 to connect the continuous rod to the transport reel. Thecoupling 150 or a similar coupling may have application to a transport reel modified to include theconnection ring 135 of the reel 110 (or a similar connection point for the coupling to secure to the reel by the connector) when the transport reel is used to remove continuous tubing from a wellsite. In addition, as described above, when coiling new continuous rod at a fabrication plant, the continuous rod may typically be coiled around the transport reel without threaded pin ends on the continuous rod. The threaded pin ends may be welded onto the continuous rod at the wellsite, with the uphole pin end being added after the continuous rod is cut to size at the wellsite. As a result, applying the apparatus and method described herein to a transport reel at a fabrication site may require welding a pin end onto the continuous rod coiled around the transport reel. -
FIGS. 13 and 14 show acoupling 250 including theconnector 260 with thering 262. Thecoupling 250 includes thebody 252 extending between thefirst end 251 and thesecond end 253. The threadedbox 254 is defined in thebody 252 proximate thefirst end 251 for threading on to the pin end of a continuous rod. Thering 262 is connected with thebody 252 by a movable joint 266 to allow thering 262 to flip with respect to thebody 252 as shown by the different position of thering 262 with respect to thebody 252 inFIG. 14 as compared withFIG. 13 . The movable joint 266 may include a hinge. The movable joint 266 may facilitate securing theconnector 260 to a reel once thecoupling 250 is threaded on to a continuous rod at the threadedbox 254 in some cases, relative to thering 62 of thecoupling 50, in which theconnector 60 extends from thebody 52 in a fixed relationship with respect to thebody 52. - The
connector 60 is located proximate thesecond end 53 of thebody 52. Theconnector 60 includes aring 62 extending from thebody 52. Thering 62 may extend from thebody 52 in a fixed relationship with thebody 52 as shown -
FIG. 15 shows acoupling 350 including thehook 364 and acover 368 connected to thebody 352. Thecoupling 350 includes thebody 352 extending between thefirst end 351 and thesecond end 353. The threadedbox 354 is defined in thebody 352 proximate thefirst end 351 for threading on to the pin end of a continuous rod. Thecover 368 may be pivoted with respect to thehook 364 to cover an open portion of thehook 364. Where theconnector 360 is for securing thecoupling 350 to a ring or other closed connection point on a reel, thecoupling 350 may facilitate securing theconnector 360 with the reel by providing anopen connector 360 with thehook 364. Theconnector 360 also facilitates connecting to a ring or other closed connection point by providing thecover 368, which may be closed after connecting theconnector 360 with the closed connection point on the reel. For example, thecoupling 350 may be secured to theconnection ring 135 of thereel 110, or any suitable closed connection point on a reel, and thecover 368 may mitigate the chance that theconnector 360 may slip off the connection point, releasing theconnector 350 and any continuous rod threaded into thebox end 354, from being secured with the reel. -
FIG. 16 shows acoupling 450 including thehook 464 and a slidingcover 469. Thecoupling 450 includes thebody 452 extending between thefirst end 451 and thesecond end 453. The threadedbox 454 is defined in thebody 452 proximate thefirst end 451 for threading on to the pin end of a continuous rod. The slidingcover 469 may be withdrawn into thebody 452 by pulling back on aswitch 467, placing the slidingcover 469 in an open position. The slidingcover 469 is shown partially withdrawn into thebody 452 inFIG. 16 . When securing thecoupling 450 to a connection point on a reel with thehook 464, the slidingcover 469 may be withdrawn into thebody 452 to allow better access to a connection point by thehook 464. Once thehook 464 is engaged with the connection point, the slidingcover 469 can be closed by emerging the slidingcover 469 from thebody 452 into a closed position. The slidingcover 469 may be translated between the open position and the closed position by using theswitch 467. - The
coupling 450 may be used with an open connection point, such as theoutside guide pin 16 of theservice reel 10. Thecoupling 450 may also be used with a closed connection point, such as theconnection ring 135 of thereel 110. Where theconnector 460 is for connecting to a closed connection point, the slidingcover 469 and thehook 464 may facilitate safely securing thecoupling 450 with the reel. For example, thecoupling 450 may be secured to theconnection ring 135 of thereel 110, or any suitable closed connection point on a reel. -
FIG. 17 shows acoupling 550 include a body 556 in which thefirst end 551 and thesecond end 553 are offset by anangle 555 with respect to one another rather than at opposed ends of an elongate body, as shown in thebodies angle 555 between theconnector 560 and the threaded box end 554 may provide advantages in some cases depending on the specific geometry of a reel with which thecoupling 550 is intended for use. Theangle 555 is close to 90 degrees, but other angles may be included in a coupling body similarly to as shown in thecoupling 550. -
FIGS. 18 to 20 show acoupling 650 with a two-part body 670. The twopart body 670 includes afirst portion 672 for connecting to a coiled rod and asecond portion 674 for connection to a reel. Thefirst portion 672 extends to thefirst end 651 of the two-part body 670 and includes the threadedbox 654. Thesecond portion 674 extends to thesecond end 653 of the two-part body 670 and includes theconnector 660. Thering 662 is connected with the body 652 by the movable joint 666 to allow thering 662 to flip with respect to the two-part body 672. The movable joint 666 includes a portion of thering 662 received within thesecond portion 674 proximate thesecond end 653. - The
first portion 672 and thesecond portion 674 are connected by aconnection 680. Theconnection 680 includes aconnection pin 682 and aconnection box 684. Theconnection pin 682 is receivable within theconnection box 684. Theconnection pin 682 includes agroove 686 and a pair of shear pins 688 may be threaded through anaperture 689 in theconnection box 684 into thegroove 686 for securing theconnection pin 682 with theconnection box 684 and securing thefirst portion 672 with thesecond portion 674. - A
first force 676 may be applied in a direction corresponding to a pull on thefirst portion 672. Asecond force 678 may be applied in a direction corresponding to a pull on thesecond portion 674. Thefirst force 676 and thesecond force 678 are opposed and result in application of stress to theconnection 680. Where the stress results in a force on theconnection 680 equal to a failure force, the shear pins 688 will shear, separating thefirst portion 672 from thesecond portion 674. - The
connection 680 separates under a force equal to or greater than the failure force. A continuous rod runaway is an event in which case the continuous rod is lost and running out of control down a wellbore. In this case, stress on a reel may be dangerous if maintained. As a result, theconnection 680 will break at a failure force likely to be experienced in a continuous rod runaway event. The failure force may be selected to correspond to the stress that would be placed on theconnection 680 under force that are lower than a dangerous level of force as expected based on previous continuous rod runaway events. - An
example coupling 650 was manufactured from J55 and low-carbon steel. In theexample coupling 650, thebox end 654 is threaded to fit 1″ API standard rod threading for continuous rod pin ends. In theexample coupling 650, thefirst portion 672 is 3 ⅞″ long and 2 ¼″ wide and thesecond portion 674 is 2 ⅜″ long. In theexample coupling 650, the shear pins 688 were ¼″ brass pins. In theexample coupling 650, thegroove 686 is ¼″ wide and 3/16″ deep, and theconnection pin 682 is ¾″ long and 1 ⅜″ wide. Theexample coupling 650 was subjected to a tension-based pull test procedure on a Satec Tensile Tester. The test was conducted between 15° C. and 32° C. With four screws placed evenly at 90° intervals radially around the two-part body 670, the ultimate load at failure was 5066 lbs. With two screws spaced across opposed sides of the two-part body 670, at 180° intervals radially, the ultimate load at failure was 2530 lbs. -
FIG. 21 shows acoupling 750 including the two-part body 770. Thecoupling 750 includes a body 752 extending between afirst end 751 and asecond end 753. A threaded box 754 is defined in the body 752 proximate thefirst end 751 for threading on to the pin end 724. Aconnector 760 is located proximate thesecond end 753 of the body 752. Theconnector 760 includes aring 762 extending from the body 752. Thering 762 may extend from the body 752 in a fixed relationship with the body 752 as shown. - In the preceding description, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the embodiments. However, it will be apparent to one skilled in the art that these specific details are not required.
- The above-described embodiments are intended to be examples only. Alterations, modifications and variations can be effected to the particular embodiments by those of skill in the art. The scope of the claims should not be limited by the particular embodiments set forth herein, but should be construed in a manner consistent with the specification as a whole..
