Definitions
- This disclosure relates generally to equipment utilized and operations performed in conjunction with a subterranean well and, in an example described below, more particularly provides a setting tool.
- Setting a packer or plug typically involves compressing a seal element in an axial direction such that it expands outward and seals against an inside of a wellbore or a well casing. Setting tools often perform this compression by holding a center section of the packer or plug stationary while driving an outer section downward. This action drives wedges and cones against elastomer seal elements that are thereby enlarged radially so a seal is created between the plug or packer and the wellbore or well casing. During the setting operation a shear pin may shear and release the setting tool from the set packer or plug, so that the setting tool may be retrieved from the well.
- setting tools Numerous types of setting tools have been employed. Most setting tools are propellant-actuated, in which flammable power charges are burned to generate pressurized gases that displace one or more pistons, in order to set the packer or plug. Some setting tools utilize hydraulic oil as an intermediary to transfer the force of the power charge to the actuator of the setting tool. Other setting tools use the pressurized gases to directly actuate the setting tool without employing hydraulic oil. Setting tools can either be reusable or disposable.

- the setting tool 5 and method are merely one example of an application of the principles of this disclosure in practice, and a wide variety of other examples are possible. Therefore, the scope of this disclosure is not limited at all to the details of the setting tool 5 and method described herein and/or depicted in the drawings.
- the setting tool 5 is desirably compact, and uncomplicated to assemble and actuate.
- the setting tool 5 is propellant-actuated and is used to set plugs, packers and other types of well tools in well casing or open hole wellbores.
- the FIG. 1 setting tool 5 has a piston, a rod, a sealed guide bushing, a retaining collar, a shear pin and a cylinder.

- the retaining collar attaches to the upper end of the cylinder and holds a shear pin that protrudes into a hole formed in the outer surface of the piston.
- the shear pin carries the weight of the tool string during run-in or installation in the well. However, once the power charge is ignited, the shear pin is sheared, thereby allowing the setting tool to actuate.

- Well packers and plugs are often put into wells and secured in place using setting tools. Setting a packer or plug typically involves compressing a seal element in an axial direction such that it expands outward and seals against an inside of a wellbore or a well casing. Setting tools often perform this compression by holding a center section of the packer or plug stationary while driving an outer section downward. This action drives wedges and cones against elastomer seal elements that are thereby enlarged radially so a seal is created between the plug or packer and the wellbore or well casing. During the setting operation a shear pin may shear and release the setting tool from the set packer or plug, so that the setting tool may be retrieved from the well.
- Numerous types of setting tools have been employed. Most setting tools are propellant-actuated, in which flammable power charges are burned to generate pressurized gases that displace one or more pistons, in order to set the packer or plug. Some setting tools utilize hydraulic oil as an intermediary to transfer the force of the power charge to the actuator of the setting tool. Other setting tools use the pressurized gases to directly actuate the setting tool without employing hydraulic oil. Setting tools can either be reusable or disposable.

FIG. 1 is asetting tool 5 and associated method which can embody principles of this disclosure. However, it should be clearly understood that thesetting tool 5 and method are merely one example of an application of the principles of this disclosure in practice, and a wide variety of other examples are possible. Therefore, the scope of this disclosure is not limited at all to the details of thesetting tool 5 and method described herein and/or depicted in the drawings. - In the
FIG. 1 example, thesetting tool 5 is desirably compact, and uncomplicated to assemble and actuate. Thesetting tool 5 is propellant-actuated and is used to set plugs, packers and other types of well tools in well casing or open hole wellbores. - As described more fully below, the
FIG. 1 setting tool 5 has a piston, a rod, a sealed guide bushing, a retaining collar, a shear pin and a cylinder. The piston has an interior chamber into which a power charge is inserted prior to use of thesetting tool 5 at a wellsite. The rod mechanically attaches to the piston, accessing the power charge chamber at one end. - The piston and rod form a rigid assembly. The sealed guide bushing mechanically attaches to the lower end of the cylinder. The cylinder and the sealed guide bushing form an assembly that slides axially along the piston and rod assembly.
- In the
FIG. 1 example, an annular-shaped space is formed between the sealed guide bushing and the piston. The rod has axial and radial ports that connect to form passages which communicate the pressurized gases from the power charge chamber to the annular-shaped space. The gas pressure in the annular-shaped space acts against the sealed guide bushing driving the cylinder and the sealed guide bushing downward along the axial length of the rod. - The gas pressure inside the annular-shaped space is retained by fluidic seals in grooves on the outer surface of the piston. These seals prevent the pressurized gases from passing between the piston outer surface and the cylinder inner surface. The sealed guide bushing has grooves on its inner bore that allow for the placement of fluidic seals. These seals prevent the pressurized gases from passing between the rod and the sealed guide bushing.
- In this example, the retaining collar attaches to the upper end of the cylinder and holds a shear pin that protrudes into a hole formed in the outer surface of the piston. The shear pin carries the weight of the tool string during run-in or installation in the well. However, once the power charge is ignited, the shear pin is sheared, thereby allowing the setting tool to actuate.
- The upper end of the piston has threads and seals for attaching to a firing head. The lower end of the rod is adapted for connecting to a well tool mandrel. The lower end of the seal guide bushing is adapted for connecting to the setting sleeve of the well tool below the setting tool.
- In the
FIG. 1 example, the power charge is placed in the power charge chamber and is ignited to generate pressurized gas. The pressurized gas enters the annular-shaped space and causes the cylinder and sealed guide bushing to stroke axially along the rod and piston assembly. The piston and rod assembly is held stationary while the cylinder and sealed guide bushing move the well tool's setting sleeve relative to the stationary mandrel, thereby causing the well tool to set. - As depicted in
FIGS. 1 & 2 , thecompact setting tool 5 is in the run-in configuration, in which it may be connected to a well tool (such as, a plug, a packer, a liner hanger, etc.) that can be set in a well. The scope of this disclosure is not limited to use of thesetting tool 5 with any particular type of well tool. - The
setting tool 5 has a generallytubular piston 27, arod 17, a sealed guide bushing 15, aretaining collar 18, a shear pin, apower charge 10, and acylinder 20. Thepiston 27 has apower charge chamber 19, anexterior circumference 34, andgrooves 30 fitted withfluid pressure seals 14. - An
upper region 26 of thepiston 27 is designed to mechanically connect and seal with a firing head or firing head adapter (not shown, seeFIG. 6 ). Thepiston 27 has ahole 32 formed in its outer surface to receive ashear pin 12 inserted through ahole 29 in theretaining collar 18. Theshear pin 12 may be press-fit in at least one of theholes - A
lower region 43 of thepiston 27 is internally threaded to form a mechanical connection with an upper threadedsection 36 of therod 17. Therod 17 has anexterior circumference 35 which slidably engages with the sealed guide bushing 15 and itsseals 16. - The
rod 17 has one or moreaxial flow ports 21 which are in fluid communication with one or moreradial flow ports 22. The upper threadedsection 36 connects to the lower end of thepiston 27 and provides a fluid connection to alower region 33 of thepower charge chamber 19. Therod 17 has a lower threadedconnection 25 which connects to a well tool mandrel (not shown inFIG. 1 , seeFIG. 6 ) located below thesetting tool 5. - The sealed
guide bushing 15 has aninterior circumference 40 andinternal grooves 31 fitted with the fluid pressure seals 16. Additionally, the sealedguide bushing 15 has an upper threadedconnection 41 which mechanically connects and seals the sealedguide bushing 15 to the lower end of thecylinder 20. Additionally, the sealedguide bushing 15 has a lower threadedconnection 24 which connects to the setting sleeve of the well tool (not shown inFIG. 1 , seeFIG. 6 ) located below thesetting tool 5. - The retaining
collar 18 has a threadedsection 42 that mechanically connects to the upper end of thecylinder 20. The retainingcollar 18 has ahole 29 that contains ashear pin 12 held in place with apliable potting compound 11. Theshear pin 12 protrudes through the retainingcollar 18 and into ashallow hole 32 formed into the upper end of thepiston 27. - The
cylinder 20 has aninterior circumference 37. Each end of thecylinder 20 is threaded (at 41, 42). The upper threadedsection 42 mechanically connects with the retainingcollar 18. The lower threadedconnection 41 mechanically connects and seals with the sealedguide bushing 15. - The
cylinder 20 has avent hole 28 formed in its side. Thevent hole 28 is filled with apliable potting compound 13. After actuation of the setting tool 5 (seeFIGS. 3 & 4 ) thishole 28 is exposed to pressurized gas in the annular-shapedspace 23. The pressurized gas pushes out thepliable potting compound 13 and then vents the pressurized gas from the annular-shapedspace 23 into the wellbore. -
FIG. 3 shows a section view of thesetting tool 5 in the actuated configuration. Theshear pin 12 has been sheared. Thevent hole 28 is in fluid communication with the annular-shapedspace 23. The annular-shapedspace 23 is lengthened due to the stroking of the sealedguide bushing 15 and thecylinder 20. Additionally, an axial distance between the lower threadedconnection 24 on the sealedguide bushing 15 and the lower threadedconnection 25 on therod 17 has been significantly reduced, indicating that the well tool connected thereto has been set. -
FIG. 5 depicts the annular-shapedspace 23 that extends radially between theexterior circumference 35 of therod 17 and theinterior circumference 37 of thecylinder 20. Additionally, the annular-shapedspace 23 extends axially between alower end surface 38 of thepiston 27 and anupper end surface 39 of the sealedguide bushing 15. Thelower region 33 of thepower charge chamber 19 is in fluid communication with the annular-shapedspace 23 via theaxial flow ports 21 and theradial flow ports 22 in therod 17. - Upon ignition, the
power charge 10 generates pressurized gases in thepower charge chamber 19. The pressurized gases move through theaxial ports 21 and theradial ports 22 within therod 17 and enter the annular-shapedspace 23. The pressurized fluids act on the sealedguide bushing 15 causing theshear pin 12 to shear and forcing the sealedguide bushing 15 and the attachedcylinder 20 downward into an actuated or set position. - Referring additionally now to
FIG. 6 , a cross-sectional view of another example of thesetting tool 5 is representatively illustrated. In this example, thesetting tool 5 is being used to set awell tool 46 in awellbore 48. Thewellbore 48 may be lined withcasing 50 or another type of wellbore lining, or the wellbore may be uncased or open hole in other examples. - The
FIG. 6 setting tool 5 is similar in many respects to theFIGS. 1-5 setting tool described above. Note, however, that theFIG. 6 setting tool 5 does include some differences over theFIGS. 1-5 setting tool. - The
guide bushing 15 and a settingsleeve 54 are combined or integrated into a single component in theFIG. 6 setting tool 5. In other examples, the settingsleeve 54 could be a separate component from the guide bushing 15 (e.g., as in theFIGS. 1-5 example). - An
adapter 56 connects between the settingsleeve 54 andupper slips 58 of thewell tool 46. The settingsleeve 54 and theadapter 56 allow a compressive force to be applied from theguide bushing 15 and thecylinder 20 to the upper slips 58 and other outer components of thewell tool 46, as described more fully below. - In addition,
ports 52 provide fluid communication between thepower charge chamber 19 and theannular space 23 axially between thepiston 27 and theguide bushing 15, and radially between therod 17 and thecylinder 20. Theports 52 are formed in the piston 27 (instead of in therod 17 as for theports FIGS. 1-5 example). - A firing
head 60 is connected to the upper end of thepiston 27. The firinghead 60 includes anignitor 62 used to ignite thepower charge 10. Theignitor 62 could be electrically or percussion-activated. Anupper connector 64 of the firinghead 60 may be used to connect to a conveyance (such as, a wireline, a coiled tubing string, etc.). - The
well tool 46 in this example is in the form of a bridge plug. Aninner mandrel 66 extends axially between alower head 68 and a releasable settingconnector 70. The settingconnector 70 includes an internally threadedsleeve 72 releasably secured in an upper end of theinner mandrel 66 by shear pins 74. - The
sleeve 72 is threaded to a lower end of therod 17. In this manner, a tensile force can be transmitted from therod 17 to theinner mandrel 66 of thewell tool 46. However, when the tensile force reaches a predetermined level, the shear pins 74 will shear, thereby freeing therod 17 from its connection to thewell tool 46. - The
well tool 46 further includes the upper slips 58, lower slips 76, upper and lowerconical wedges seal element 82 positioned between the wedges. When the compressive force is applied via theadapter 56 to the upper slips 58, and the opposite tensile force is applied via therod 17 to theinner mandrel 66, the external components (the upper andlower slips lower wedges well tool 46 will be axially compressed, thereby deforming theseal element 82, so that it extends radially outward and sealingly engages thecasing 50 orwellbore 48, and thereby deflecting the slips outward into gripping engagement with the wellbore or casing. - When the tensile force transmitted from the
rod 17 to theinner mandrel 66 reaches the predetermined level at which thewell tool 46 is considered sufficiently set (theslips wellbore 48 orcasing 50, and theseal element 82 sealingly engaging the wellbore or casing), the shear pins 74 shear, and then thesetting tool 5 is released from the well tool. Thesetting tool 5 can be retrieved from the well, leaving thewell tool 46 set downhole. - Referring additionally now to
FIG. 7 , a cross-sectional view of thesetting tool 5 is representatively illustrated in the run-in configuration. Thesetting tool 5 is depicted apart from thewell tool 46 and firinghead 60 ofFIG. 6 . Thesetting tool 5 may be used with other well tools or firing heads, in keeping with the principles of this disclosure. - In
FIG. 7 it may be recognized that thissetting tool 5 example is made up of only four generally tubular main components (thepiston 27, retainingcollar 18,cylinder 20 and guidebushing 15/setting sleeve 54) and one solid main component (the rod 17). In other examples, the retainingcollar 18 and thecylinder 20 could be combined or theguide bushing 15 and settingsleeve 54 could be separated. Thus, the scope of this disclosure is not limited to any particular number, shapes or combinations of components in thesetting tool 5. - Note that the
ports 52 extend through thepiston 27 to the annular space 23 (seeFIG. 8 ) between thepiston 27 and theguide bushing 15. At an opposite end, each of theports 52 is open to thepower charge chamber 19 where it is not blocked by therod 17. Thus, theannular space 23 is in communication with thepower charge chamber 19, without extending through or being blocked by therod 17. - Referring additionally now to
FIG. 8 , a cross-sectional view of thesetting tool 5 is representatively illustrated in the actuated configuration. In this configuration, the power charge 10 (seeFIG. 6 ) has burned in thechamber 19 and pressurized gases have been communicated from thechamber 19 to theannular space 23. Theshear pin 12 has sheared and theguide bushing 15/settingsleeve 54, the retainingcollar 18 and thecylinder 20 have been displaced axially downward (to the right as viewed inFIG. 8 ) relative to therod 17 andpiston 27. - Referring additionally now to
FIG. 9 , a cross-sectional view of a portion of thesetting tool 5 is representatively illustrated in the actuated configuration. In this view it may be seen that the retainingcollar 18 prevents displacement of thepiston 27 out of the upper end of thecylinder 20. - In addition, it may be seen that the
ports 52 intersect thepower charge chamber 19 above (to the left as viewed inFIG. 9 ) therod 17. Theports 52 intersect thelower surface 38 of thepiston 27 between thecylinder 20 and therod 17. Theports 52 extend through thepiston 27 radially between theseals 14 andthreads 44 that connect the piston to therod 17. - It may now be fully appreciated that the above disclosure provides significant advantages to the arts of designing, constructing and utilizing setting tools for use in subterranean wells. In examples described above, the
setting tool 5 is specially designed so that tubular components are separated from solid cylindrical components for reduced manufacturing cost and ease of transport and assembly. Thepiston 27 is separate from therod 17. Thepower charge chamber 19 is not formed in therod 17. Instead, thepower charge chamber 19 is formed in thepiston 27, and then the piston is connected to therod 17 during assembly of thesetting tool 5. - The above disclosure provides to the art a

Theguide bushing 15 may be separate from thecylinder 20 and threadedly secured to thecylinder 20. - The
setting tool 5 may include a settingsleeve 54 extending outwardly from theguide bushing 15. The settingsleeve 54 may be integrally formed with theguide bushing 15. - Also provided to the art by the above disclosure is another
