Definitions

  • the field of the invention is compression set packers and more particularly a release mechanism that sequentially releases the packer seal and then the slips before packer retrieval.
  • Retrievable compression set packers typically have a pair of opposed slips straddling a sealing element.
  • a setting piston creates relative movement that sets the packer. The relative movement pushes an upper slip out on a ramp to anchor the mandrel. Further pushing compresses the sealing element to contact the surrounding tubular followed by pushing the lower slips outward into engagement with the surrounding tubular.
  • a locking mechanism locks in the relative movement that set the packer slips and seal.
  • a retrievable compression set packer is sequentially released. First the sealing element is allowed to relax. Then the upper slip has wedging action that forces it against a surrounding tubular relaxed. After that the upper slips are pulled up to retract them fully allowing the packer to come out. These sequential actions are done with a mandrel movement in one direction.
  • the sealing element is released with undermining a collet by aligning collet heads with a recess on the mandrel.
  • the slip force release happens with mandrel movement forcing a ring into a wedge such that circumferential force on slip segments is reduced or eliminated when the wedge is pushed out of its conforming slot allowing for circumferential flexibility of the slip seat.
  • the mandrel picks up a slip ring that retracts the slip segments on the seat and the packer is removed.
  • FIG. 1 a is a section view of the retrievable packer when running in
  • FIG. 1 b is the view of FIG. 1 a with the sealing element and upper slips released for retrieval;
  • FIG. 2 a is an enlarged view of a part of FIG. 1 a;
  • FIG. 2 b is an enlarged view of a part of FIG. 1 b;
  • FIG. 3 a is an exterior plan view of a part of the packer shown in FIG. 1 a;
  • FIG. 3 b is an exterior plan view of a part of the packer shown in FIG. 1 b.
  • FIG. 1 a shows a mandrel 10 having a passage 12 therethrough.
  • An outer assembly 14 starts with a slip ring 16 at the downhole end followed by lower slips 18 that ride on a ramped slip seat 20 .
  • Adjacent the slip seat 20 is an anti-extrusion ring 22 and a seal assembly generally referred to as 24 .
  • Another anti-extrusion ring 26 is held in place with telescoping sleeve 28 secured against telescoping to a shorter axial dimension by collet 40 extending from a collet ring 30 .
  • Upper sleeve 32 retains upper slip seat 34 that interacts with the upper slips 36 that are interconnected by slip ring 38 .
  • Collet ring 30 has a series of collet heads 40 secured to sleeve 28 with meshing tooth profiles 42 . Heads 40 are supported off mandrel 10 for running in. Recess 44 is offset from heads 40 when running in but when the release process is started and mandrel 10 is picked up the first thing that happens is that recess 44 aligns with heads 40 .
  • the retained rubber pressure in the seal 24 can push sleeve 28 to the point that surface 46 hits surface 48 on collet ring 30 .
  • the seal assembly can then relax and stretch to the position shown in FIG. 1 b where a part of the assembly with extrusion ring 26 is pulled away from the balance of the seal assembly 24 to allow reduction of diameter that it will take to allow removal of the packer.
  • the configuration of the seal assembly and slips can be altered as long as the slip design is amenable to a release of most if not all the force holding the slips to the surrounding tubular when the mandrel is moved.
  • the preferred design allows mandrel movement to reduce holding force before there is axial slip movement.
