Definitions

  • the field of the invention is plugs that disintegrate and more particularly plugs with compression set sealing elements that disintegrate and that further have a shortened mandrel to the top of a slip cone to facilitate the disintegration.
  • Fracturing is a process to enhance hydrocarbon delivery from a formation to a surface location.
  • the fracturing is frequently a sequential process where a plug is set and a perforating gun that was run in with the plug is released from the plug and shot into the formation to create fractures. These fractures are then extended with high pressure slurry of proppant or typically mostly sand to open the perforation and hold them open by remaining in the perforation after the high pressure flow is cut off.
  • the zone with the recently produced fractures from the perforating gun is sometimes isolated by dropping a ball on the seat of the plug to close off a passage through the plug so that pressure into the formation can be built up to deliver the proppant and further open or propagate the initially made fractures with the perforating gun.
  • What is needed and provided by the present invention is a packer or plug design that has degrading metallic components preferably made with controlled electrolytic materials (CEM) and sold under the brand In-tallic by Baker Hughes Incorporated of Houston Texas and described in US 2011/0136707 and related applications filed the same day.
  • the sealing element is preferably 85A-95A TDI-Ester Polyurethane that is axially compressed to increase in radial dimension.
  • CEM controlled electrolytic materials
  • the mandrel is shortened to support the top of the cone for the slips so that there is less bulk to the plug and it can disintegrate faster.
  • the inventors have discovered that sealing in fracking applications can be achieved with a compression set packing element that disintegrates. This goes contrary to the prevailing thinking that has focused on pushing sealing elements up ramps to get a seal or radially expanding rings from within with swage assemblies. Instead, the present invention combines the reliability of known plug designs that push slips out on a cone and then axially compress a sealing element and lock the set in a combination with materials that degrade to reduce or eliminate subsequent drilling out. To aid the disintegration process the mandrel is shortened to not go under the slip cone but instead to support the slip cone by its upper end so that there is less mandrel bulk to disintegrate with no sacrifice in structural integrity.
  • a slip ring is provided with external irregular surface that is coated with grip enhancing grit as part of a slip assembly that can disintegrate.
  • the application technique takes into account the sensitivity of disintegrating slip material to heat when the grit coating is adhered to the slip body.
  • a compression set sealing element preferably 85A-95A TDI-Ester Polyurethane is compressed axially and retained against extrusion by CEM anti-extrusion rings.
  • the compressed state of the sealing element is locked in by a degradable lock ring assembly.
  • the mandrel is secured to an upper end of a slip cone and a breakable slip ring is secured by a wireline setting tool until the set position is reached.
  • the slip ring breaks into segments that are pulled up the slip cone as the setting tool pushes on a sleeve to axially compress the sealing element and lock in the set.
  • the sealing element is retained against extrusion by CEM anti-extrusion rings.
  • a slip ring has external wickers and a coating of grit is applied in a manner that preserves the strength of the disintegrating slip body for enhancement of grip.
  • FIG. 1 illustrates a section view of the disintegrating packer or plug in the run in position with the setting tool in support thereof;
  • FIG. 2 is a section view of a slip ring and cone in the run in position.
  • a slip ring 10 is an initial ring structure of slips that are circumferentially connected with breakable tabs that are not shown so that on setting which forces ring 10 onto cone 12 the resulting slips 14 separate from each other and wedge themselves against the surrounding borehole wall that is not shown.
  • a wireline setting tool 16 of a type well known in the art and sold by Baker Hughes Incorporated as a Model E-4 supports the plug 18 to the desired subterranean location. The setting tool 16 pushes down on sleeve 20, which is a part of the setting tool 16 and comes out of the hole after the plug or packer is set, in the direction of arrow 22.
  • the internal dimension of the sealing element assembly conforms to the cylindrical shape of the outer wall of the mandrel 50 and does not change as the sealing element assembly 32 is axially collapsed.
  • the axial compression of assembly 32 also extends the anti-extrusion rings 38 and 40 against the borehole wall to retain the sealing element 42, which can be a single sleeve or multiple sleeves, in between in the set position against the borehole wall.
  • the seal rings 49 retain the sealing element 42 to the mandrel 50 to prevent swabbing-off the sealing element 42 during the installation of the plug in the borehole.
  • These plugs are typically installed in horizontal wells and high rate fluid flow is used to push the plug to the desired location. This fluid flow exerts a force to pull the sealing element 42 off the Mandrel 50.
  • an internal ring 44 can also be used under seal 42.
  • Seal 42, ring 44, rings 38 and 40 or locking member 34 can also be made of polymers such as PC-PPDI, PC-MDI, PD-TDI, Ether-PPDI, Ether-MDI, Ether-TDI, Esther- PPDI, Ester-MDI, Ester-TDI or PGA .
  • the plug mandrel 50 extends from the lock ring assembly 34 on the upper end to lower end 52 that has a thread 54 connected into upper end 56 of the cone 12. Thread 54 is the amount of extension of the mandrel 50 into the cone 12.
  • Mandrel 50 and cone 12 have aligned passages for mounting to the setting tool 16. Alternatively the mandrel 50 can be integral with the cone 12.
  • the mandrel 50 including the lock ring assembly 34, the cone 12, the slips 14, internal ring 44, seal rings 49 and the anti-extrusion rings 38 and 40 as well as the bottom sub 26 are all made of a disintegrating material that is preferably CEM or another material that responds to existing or added well fluids or exposure over time to thermal or chemical inputs.
  • the sealing assembly 32 is preferably made of 85A-95A TDI-Ester Polyurethane or a material that disintegrates under similar conditions as the balance of the plug or packer.
  • the mandrel 50 that stays in the hole is made short by ending it at the top of the cone 12 so that there is less of it to degrade so that the overall disintegration time is reduced.
  • slips 14 are not supported by the mandrel 50 but instead when set are wedged between the borehole wall that is not shown and the cone 12.
  • the present invention is in a sense back to the future in that the basic elements of a compression set packer have been fitted into an assembly that can reliably seal and disintegrate. Modifications have been further made to minimize the bulk of the packer or plug while retaining structural integrity to promote more rapid disintegration. The shorter mandrel also promotes the use of a larger bore through the plug or packer and exposes more surface area to well fluids to accelerate the disintegration process.
  • disintegrate, degrade, fail, dissolve or other terms are meant to be used interchangeably to connote an end to functional utility of the structure in the process of coming apart in pieces and ultimately disappearing or being circulated out to the surface.
  • Slip ring 10 is preferably made from magnesium but other materials such as chrome steel alloys nickel alloys; stainless alloys; carbide alloys; copper alloys; bronze; brass; aluminum and zinc to name some examples.
  • Ring 10 has a surface roughness 60 that can have a grit coating 62 for enhanced grip.
  • the application process utilizes two wires of desired materials in a spray gun which facilitates a high current between them. The current causes the wires to melt while an air channel pushes the resulting grit onto the surface of the base metal. Parameters are set such that the particles create a rigid surface capable of producing an anti-slip feature, rather than a smooth, wear-resistant surface.
  • This coating may be additive to provide a thicker layer ranging from, but not limited to, 0.010" - 0.060".
  • the ring 10 has scores 46 that allow the ring to break into segments as the swage 12 advances to then push the segments out further radially to engage the surrounding tubular.

Abstract

L'invention concerne un élément d'étanchéité d'ensemble de compression, de préférence en Polyuréthane TDI-Ester 85A-95A, qui est comprimé axialement et empêché d'extrusion par des bagues anti-extrusion CEM. L'état comprimé de l'élément d'étanchéité est verrouillé par un ensemble de bague de verrouillage dégradable. Le mandrin est fixé à une extrémité supérieure d'un cône de glissement et une bague de glissement pouvant être rompue est fixée par un outil de réglage de câble métallique jusqu'à ce que la position de consigne est atteinte. La bague de glissement se rompt en segments qui sont tirés au-dessus du cône de glissement lorsque l'outil de réglage pousse sur un manchon pour comprimer axialement l'élément d'étanchéité et le bloquer dans l'ensemble. L'élément d'étanchéité est empêché d'extrusion par des bagues anti-extrusion CEM. Lorsque l'outil de réglage est retiré, un siège de rotule est exposé pour la distribution d'une bille pour établir la pression dans la formation pour une fracturation. La totalité du bouchon se désintègre ensuite lors d'une exposition à un fluide de puits.
