- This application is a continuation of U.S. patent application Ser. No. 14/552,142, filed Nov. 24, 2014, which application claims the benefit of U.S. Provisional Application 61/907,447, filed Nov. 22, 2013, entitled “Packer Bridge Plug with Slips,” and also claims the benefit of U.S.
Provisional Application 62/051,694, filed Sep. 14, 2014, entitled “Packer Bridge Plug with Slips.” Each of these application is incorporated herein by reference. - The present invention relates to a bridge plug packer having a ball seat and packer element for sealing one zone of a well from another.
- In the process of fracking, it is expensive to run tools into and out of the well. It is therefore desirable to run in tools that can serve multiple purposes during the fracking process. The present invention in at least one embodiment is to a packer tool that can be used to seal a well bore and when the ball is removed presents only a small resistance to the production flow up through the plug.
- Accordingly, it is a principal object of a preferred embodiment of the invention to provide a packer plug that can be tripped into a particular location in a well bore and set using slips or expansion rings and packer elements. The plug presents little flow resistance because of its wide inner diameter throat through the mandrel. A ball seat at an upper end allows for the sealing of the interior passage. The ball can be flowed upward or dissolved to remove the seal and allow flow through the plug.
- It is another object of the invention to provide a selectively sealable down hole tool that can be sealed and unsealed during the fracking process without having to trip the entire tool back up the well bore.
- It is a further object of the invention to a bridge plug for use with a removable ball or with a dissolvable ball to allow production flow through the tool without requiring removal of the tool.
- Still another object of the invention is to provide a down hole tool that can be set with a setting tool to set one or more bridge plugs in series to isolate a number of zones in a well bore which can be selectively unsealed to allow production flow through the tool.
- It is an object of the invention to provide improved elements and arrangements thereof in an apparatus for the purposes described which is inexpensive, dependable and fully effective in accomplishing its intended purposes.
- These and other objects of the present invention will be readily apparent upon review of the following detailed description of the invention and the accompanying drawings. These objects of the present invention are not exhaustive and are not to be construed as limiting the scope of the claimed invention. Further, it must be understood that no one embodiment of the present invention need include all of the aforementioned objects of the present invention.

- The present invention relates to a bridge plug packer having slips.
- A bridge plug is used to isolate a zone below the plug. It is desirable to make a bridge plug that can be reversed by simply flowing fluid up from beneath the plug. The current inventions shows one
such plug 10 in the Figures. -
FIG. 1 shows abridge plug 10. The plug has acentral body 12 terminating in acollet 14. Thebridge plug 10 has a set ofslips 16 on the bottom end of the packer that when set keep thefrac plug 10 in place. The rubber element/packer 18 is contained between theexpansion rings 20 on the top and theexpansion rings 22 above the cone on the bottom. The expansion rings may have a cut section to allow the rings to contract and expand. Arubber retainer ring 24 may be provided on either side of the packer to retain the packer in position on theplug 10. As the expansion rings are compressed towards each other therubber packer 18 expands outwardly to lock the plug in place and isolates the zone upstream of the plug from the downstream zone. - The
slips 16 are located between anupper cone 26 and alower cone 28.Upper cone 28 has locknut 30 andlower cone 28 includes alocknut 32. These locknut cooperate with threading/ridges 34 on the mandrel/central body 12 to selectively locate the cones at a particular axial location along the mandrel to for example, retain the slips in a deployed status. Preferably themandrel 12 includesthreads 34 that allow thelower locknut 32 to be threaded into position, but the threads also cooperate with the lockring to act as a ratchet so that the mandrel can move downwardly past the lockring when the setting tool strokes or when a downward force acts on the mandrel body to further set theslips 16. - A number of shear pins 36 (
FIG. 2 ) are provided to lock the upper and lower cones relative to the mandrel before setting. As described lower under, when the pins shear under downward pressure from the mandrel, the cones compress the slip, forcing the slip outward to engage the well bore (not shown). The pressure required to shear the pins may vary according to the application, but are preferably set to shear during the stroking of the setting tool. - In operation, the plug is run in the well with wireline pump down, tractor or tubing (not shown). The plug is set with a special setting kit 50 (
FIG. 3 ) that attaches to the bottom section of the Packer plug by asetting collet 52. The setting collet is arranged such that the setting collet arms fall within the voids between themain mandrel 12 collet arms. The ends of the setting collet arms extend outwardly to engage with the lower cone. Thesetting mandrel 50 body prevents the setting collet arms from moving inward. Ashear ring 54 is provided to release the setting kit mandrel body at the appropriate time. When the setting mandrel body is removed, thesetting collet 52 arms can move inwardly to release the kit from thebridge plug 10. The setting mandrel body has a limited “lost motion” where the setting mandrel body can move relative to the setting collet before the mandrel body hits ashoulder 56 of the collet. When the setting mandrel body is thus positioned, the collet arms can retract. Further movement of the setting mandrel body upward causes a shoulder of thesetting mandrel body 50 to force the setting collet body upward with the setting mandrel body so that the setting kit can be removed from the bridge plug entirely. A cap (not shown) may be provided at the terminus of the setting mandrel body to keep the sheer ring from falling off entirely from the setting kit. -
FIG. 3 shows asetting gun 48 inside a setting sleeve attached to the bridge plug by the setting kit and ready for insertion into a well bore. The setting gun is connected to the setting kit mandrel byadapter sleeve 62, which is attached to the bridge plug bycollet 52 which is held in place byshear ring 54. The setting tool includes acollet 56 that includes a number arms/fingers 52. The arms are sized and arranged to fit within the slots provided on thecollet 14 of the mandrel body 12 (FIG. 2 ). This provides a shorter tool and provides for a fixed orientation of the setting tool relative to the mandrel during tripping in and setting. - During setting, the tools are tripped into a well bore to a desired location. The slips are partially set as the tool is tripped in to provide some resistance. This resistance causes the packer elements to partially set. The setting tool then strokes the bottom of the setting tool pulls up on the
lower cone 28.Threads 32 allow the lower cone to raise up along the mandrel body pushing the slips againstlower cone 26. The conical section of thecone 26 slides within theslips 16 to expand the slips. Frangible sections between the slips allow the slips to further expand. - The setting tool further compresses the bridge plug causing the rings around the packer element to compress the
packer element 18 therebetween. While optional, the rings provide a buffer around the packer element. The rings may have precut sections to allow the rings to expand as well along with the packer element. - When the force reaches a sufficient pressure to shear the shear pins on the setting mandrel, the pin(s) shear on the
lock ring 54 to separate the lock ring from the setting body. The shear ring collects at a lower portion of the shear kit so that it can be retrieved with the tool. - With the lock ring removed, the
setting tool 50 can move upward relative to theplug mandrel body 12. The setting tool can move upward within themandrel 12 so that the expandedsection 58 of the setting tool is moved axially above the collet arms andfingers 52. With the reduced neck of the setting tool beneath thefingers 52, the fingers are free to collapse inwardly. As the shoulder of the expanded section hits thebase 56 of the setting tool collet, thefingers 52 collapse allowing the setting tool to release from thebridge plug mandrel 12. The setting tool is then tripped up leaving the bridge plug set in place. Because the bridge plug is hollow, fluid can still flow unobstructed through the well bore. The cylindrical shape of the tool allows for the flow to bridge plug to only have a minor impact on flow through the well bore. - The next operation is to isolate the zones below the plug by pumping a ball on to the top of the Packer Plug. A
ball 70 is pumped down from surface and lands on the top of the Packer Plug blocking flow through the interior of the bridge plug as the packer element blocks flow around the bridge plug. The additional feature of the ball landing on the top of the Packer plug is that this pushes additional force on the mandrel though the lock nut and down to the low slips. This force energizes the element more and puts more energy into the slips of the Packer tool. - The final operation is the flow back and production. With the mandrel being a large cast iron Mandrel, the fluids and gasses in the well will not break down the tool like a composite plug. Because the Bottom of the Packer mandrel has a collet style design with arms having ample voids between the arms, the well fluids will flow around any ball that comes in contact with the bottom of the Packer mandrel and will flow through the voids in the collet and through the interior of the bridge plug.

FIGS. 4-6 show a further embodiment of the invention having expansion rings instead of slips. The arrangement of this embodiment allows for a simplified design and a reduced overall length of the tool. - The
tool 110 has acentral mandrel 112 having apacker element 118 mounted thereon. The mandrel includes aball seat 113 for theball 170 to seal the inner passageway through the mandrel. The lower end of mandrel body includescollet fingers 114 for attaching additional elements to the mandrel. Afrustoconical ring 125 takes the place ofupper cone 26. Thelower cone 128 has a conical surface to enclosed a number of expansion rings 115 between the lower cone and the 26 and to force the expansion rings to expand when compressed between the lower cone and thering 125. The expansion rings 115 may have a weakened area or a cut to allow the rings to expand when compressed between the conical surfaces. The expansion ring may haveadditional friction elements 117 to provide a secure bite between the bridge plug and the well casing when it is desired to set the plug in place. The frictional elements could be made of carbide or may be wickers similar to the slip design of the first embodiment. Other materials including metals and ceramics could be used for the construction of thefrictional elements 117 depending on the application. - In practice, the lower cone is threaded onto the mandrel body and shear pinned into place. A setting tool similar to
FIG. 3 is used to bottom set the bridge plug in place. During setting, the lower cone shears thepin 129 and moves upwardly along the mandrel body to compress the expansion rings between the cone of thelower cone 128 and thering 125 forcing the expansion rings outward. the expansion rings engage the inner wall of the casing as they expand forcing the expansion rings and/or thefrictional elements 117 into frictional engagement with the casing to affix the bridge plug into place. Further compression expands thepacker element 118 outward to prevent any flow around the outside of the bridge plug. Aball 170 is then dropped into place to selectively seal the bridge plug. If required, the ball can be dissolved or removed to reopen the flow through the tool to allow production or other flow therethrough without requiring the removal of the tool. - While this invention has been described as having a preferred design, it is understood that it is capable of further modifications, uses and/or adaptations of the invention following in general the principle of the invention and including such departures from the present disclosure as come within the known or customary practice in the art to which the invention pertains and as maybe applied to the central features hereinbefore set forth, and fall within the scope of the invention and the limits of the appended claims.
