Abstract
Methods and apparatus create an attachment and a seal between two tubular members in a wellbore. An expandable assembly includes a packer and liner hanger to be expanded into a surrounding tubular. The packer can be a longitudinally corrugated packer and can have a sealing element disposed on an outer surface thereof.
The liner hanger can include a plurality of formations extending outward along an outer surface of the liner hanger to form interspaces for longitudinal fluid flow between the formations.
In operation, an expansion tool moves axially through an inner diameter of the expandable assembly to expand the liner hanger with a fluted expander and subsequently the packer with a substantially uniform outer diameter cone.
The liner hanger can include a plurality of formations extending outward along an outer surface of the liner hanger to form interspaces for longitudinal fluid flow between the formations.
In operation, an expansion tool moves axially through an inner diameter of the expandable assembly to expand the liner hanger with a fluted expander and subsequently the packer with a substantially uniform outer diameter cone.
Claims (21)
1. A system for completing installation of a liner in a wellbore, comprising:
a longitudinally corrugated packer having a sealing element disposed on an outer surface thereof; and a liner hanger coupled with the packer and the liner, wherein a plurality of formations extend outward along an outer surface of the liner hanger to form interspaces for longitudinal fluid flow between the plurality of formations.
a longitudinally corrugated packer having a sealing element disposed on an outer surface thereof; and a liner hanger coupled with the packer and the liner, wherein a plurality of formations extend outward along an outer surface of the liner hanger to form interspaces for longitudinal fluid flow between the plurality of formations.
2. The system of claim 1, further comprising an expansion tool operatively coupled with the hanger and packer, wherein the expansion tool comprises a fluted member and a conical member having a substantially uniform maximum outer diameter.
3. The system of claim 1, further comprising:
a fluted expansion member; and a conical expansion member having a substantially uniform maximum outer diameter, wherein the expansion members are separated a predetermined distance from one another based on a length of the packer and hanger combined.
a fluted expansion member; and a conical expansion member having a substantially uniform maximum outer diameter, wherein the expansion members are separated a predetermined distance from one another based on a length of the packer and hanger combined.
4. The system of claim 1, further comprising a fluted expander for expanding the liner hanger, wherein the fluted expander is dimensioned to pass through the packer substantially without interference.
5. The system of claim 1, wherein crests of the packer correspond in rotational alignment with the interspaces on the liner hanger.
6. The system of claim 1, further comprising a fluted expander operatively coupled with the hanger to permit longitudinal relative movement between the expander and the hanger and rotationally align protrusions of the expander with crests of the corrugated packer and the interspaces of the hanger.
7. The system of claim 1, wherein the sealing element is disposed between circumferential projections along an outer surface of the packer.
8. The system of claim 1, further comprising a polish bore receptacle disposed between the liner and the liner hanger.
9. The system of claim 1, wherein the liner hanger is disposed between the liner and the packer.
10. The system of claim 1, wherein the sealing element comprises an elastomeric material.
11. The system of claim 1, wherein the formations comprise raised portions around the outside surface that otherwise defines a substantially circular profile.
12. The system of claim 1, further comprising hard inserts disposed along the formations.
13. The system of claim 1, further comprising hard inserts disposed along the formations, wherein the inserts are oriented in substantially one direction.
14. A method of completing installation of tubing in a wellbore, comprising:
running a first tubular into the wellbore to a position coaxially within a portion of a second tubular disposed in the wellbore, wherein a first length of the first tubular is distinct from and above a second length of the first tubular;
expanding the second length of the first tubular into gripping contact with the second tubular without altering a corrugated profile of the first length, wherein circumferentially separated longitudinal areas of the second length remain spaced from the second tubular to provide a flow path after expanding the second length;
and expanding the first length of the first tubular into circumferential sealing contact with the second tubular after expanding the second length.
running a first tubular into the wellbore to a position coaxially within a portion of a second tubular disposed in the wellbore, wherein a first length of the first tubular is distinct from and above a second length of the first tubular;
expanding the second length of the first tubular into gripping contact with the second tubular without altering a corrugated profile of the first length, wherein circumferentially separated longitudinal areas of the second length remain spaced from the second tubular to provide a flow path after expanding the second length;
and expanding the first length of the first tubular into circumferential sealing contact with the second tubular after expanding the second length.
15. The method of claim 14, wherein expanding the first length includes passing a conical member having a substantially uniform maximum outer diameter through the first length.
16. The method of claim 14, wherein expanding the first length includes passing an at least partially compliant cone through the first length, wherein an outer diameter of the cone is capable of deforming in response to restrictions.
17. The method of claim 14, wherein expanding the second length includes passing a fluted member through the second length.
18. The method of claim 14, wherein expanding the second length includes passing a fluted member through the second length while ribs of the fluted member are rotationally misaligned with formations extending outward along an outer surface of the second length.
19. The method of claim 14, wherein expanding the first length places a seal disposed on an outside of the first length into contact with the second tubular.
20. A method of completing installation of a liner in a wellbore, comprising:
providing a packer comprising tubing with a longitudinally corrugated profile;
providing a liner hanger coupled with the packer and the liner, wherein a plurality of circumferentially spaced longitudinal formations extend outward along an outer surface of the liner hanger;
moving an expander longitudinally through the liner hanger while a plurality of protrusions on the expander are misaligned with the formations, thereby expanding the liner hanger in a radial direction to place the formations into frictional contact with a surrounding tubular disposed in the wellbore leaving a flow path between the formations; and expanding the packer into circumferential sealing contact with the surrounding tubular after expanding the liner hanger.
providing a packer comprising tubing with a longitudinally corrugated profile;
providing a liner hanger coupled with the packer and the liner, wherein a plurality of circumferentially spaced longitudinal formations extend outward along an outer surface of the liner hanger;
moving an expander longitudinally through the liner hanger while a plurality of protrusions on the expander are misaligned with the formations, thereby expanding the liner hanger in a radial direction to place the formations into frictional contact with a surrounding tubular disposed in the wellbore leaving a flow path between the formations; and expanding the packer into circumferential sealing contact with the surrounding tubular after expanding the liner hanger.
21. The method of claim 20, wherein expanding the packer places a seal disposed on an outside of the packer into contact with the surrounding tubular.
