Abstract

A tubing hanger assembly including an outer hanger body (8) lands on a load shoulder (10) of a tubing head. Additionally, an inner hanger body (9) having at least one inner hanger groove (19) moves vertically up and down with respect to the outer hanger body and engages at least one downhole device. A first latch ring (11) expands into a groove (12) of the tubing head to lock the outer hanger body in position and a sleeve (14) with a plurality of grooves (20) is disposed between the outer hanger body and the inner hanger body of the tubing hanger assembly. Furthermore, a second latch ring (15), disposed between the sleeve and the inner hanger body, expands into or collapse out of the at least one inner hanger groove (19) and the plurality of grooves (20) on the sleeve (14), and the second latch ring (15) is a tension loading support for the inner hanger body.

First claim

What is claimed:

1. A tubing hanger assembly, comprising:
an outer hanger body configured to land on a load shoulder of a tubing head;
an inner hanger body having at least one inner hanger groove and configured to move vertically up and down with respect to the outer hanger body and engage at least one wellbore device;
a first latch ring configured to expand in a groove of the tubing head to lock the outer hanger body in position;
a sleeve with a plurality of grooves disposed between the outer hanger body and the inner hanger body of the tubing hanger assembly; and
a second latch ring disposed between the sleeve and the inner hanger body, wherein the second latch ring is configured to expand into or collapse out of the at least one inner hanger groove and the plurality of grooves, and the second latch ring is a tension loading support for the inner hanger body,
wherein the sleeve is movable, and the movable sleeve comprises a bottom stop to engage the inner hanger body.

2. The tubing hanger assembly of claim 1 , wherein the second latch ring is fixed vertically with respect to the movable sleeve.

3. The tubing hanger assembly of claim 1 , further comprising a threaded nut connected to the outer hanger body.

4. The tubing hanger assembly of claim 3 , wherein the threaded nut comprises a stop shoulder configured to limit the vertical movement of the inner hanger body.

5. The tubing hanger assembly of claim 1 , wherein the tubing head is ported.

6. A method, comprising:
landing an outer hanger body of a tubing hanger assembly on a load shoulder of a tubing head;
locking the outer hanger body of the tubing hanger assembly in position with a first latch ring expanding into a groove of the tubing head;
moving down an inner hanger body of the tubing hanger assembly to engage at least one wellbore device and moving the inner hanger body up;
collapsing a second latch ring into at least one inner hanger groove;
moving up the inner hanger body to expand the second latch ring into one of a plurality of grooves in a sleeve to provide a tension load support for the inner hanger body and the at least one wellbore device; and
expanding the second latch ring in a second of the plurality of grooves by further moving up the inner hanger body, and moving the inner hanger body down and disengaging the at least one wellbore device.

7. The method of claim 6 , further comprising moving the sleeve along with the inner hanger body.

8. The method of claim 6 , further comprising moving the second latch ring along with the inner hanger body.

9. The method of claim 6 , further comprising threading a nut to the outer hanger body to stop the inner hanger body and collapse the second latch ring.

10. The method of claim 9 , further comprising unthreading the nut from the outer hanger body to further move the inner hanger body and expand the second latch ring.

11. The method of claim 6 , further comprising engaging a down hole packer with the at least one wellbore device.

12. The method of claim 6 , further comprising disposing the tubing head on a wellhead.

13. The method of claim 6 , further comprising collapsing the first latch ring to retrieve the tubing hanger assembly.

14. A system, comprising:
a wellhead;
a tubing head with a load shoulder;
a tubing hanger assembly, comprising:
an outer hanger body configured to land on the load shoulder of the tubing head;
an inner hanger body having at least one inner hanger groove and configured to move vertically up and down with respect to the outer hanger body and engage at least one wellbore device;
a first latch ring configured to expand in a groove of the tubing head to lock the outer hanger body in position;
a sleeve with a plurality of grooves disposed between the outer hanger body and the inner hanger body of the tubing hanger assembly; and
a second latch ring disposed between the sleeve and the inner hanger body, wherein the second latch ring is configured to expand into or collapse out of the at least one inner hanger groove and the plurality of grooves, and the second latch ring is a tension loading support for the inner hanger body,
wherein the sleeve is movable, and the wherein the movable sleeve comprises a bottom stop to engage the inner hanger body.

15. The system of claim 14 , wherein the second latch ring is fixed vertically with respect to the movable sleeve.

16. The system of claim 14 , further comprising a threaded nut connected to the outer hanger body.

17. The system of claim 16 , wherein the threaded nut comprises a stop shoulder configured to limit the vertical movement of the inner hanger body.

18. The system of claim 14 , wherein the at least one wellbore device is a tubing string to engage a down hole packer.

19. The system of claim 14 , wherein the tubing head is ported.

20. The system of claim 14 , wherein the tubing head is disposed on the wellhead.
