Abstract

A downhole tool setting system includes a tubular member that defines a bore therethrough; a downhole tool positioned to ride the tubular member between a partial set position and a final set position; and a locking system coupled to the downhole tool and configured to adjust the downhole tool from the partial set position based on at least a portion of the locking system moveable relative to the tubular member to the final set position based on at least a portion of the locking system affixed to the tubular member.

First claim

What is claimed is:

1. A downhole tool locking system, comprising:
a tubular mandrel that defines a bore therethrough, the mandrel comprising a profile formed on an outer radial surface of the mandrel;
a carrier ring positioned to ride the tubular mandrel adjacent an outer radial surface of the tubular mandrel, the carrier ring comprising a profile formed on an outer radial surface of the carrier ring;
a body lock ring comprising a first profile formed on an inner radial surface to engage the profile formed on the outer radial surface of the carrier ring, and a second profile formed on an outer radial surface of the body lock ring; and
a housing comprising a profile formed on an inner radial surface of the housing to engage the second profile of the body lock ring, where the body lock ring is adjustable from a first position engaged with the carrier ring through engagement of the carrier ring profile and the first profile of the body lock ring to a second position engaged with the mandrel through engagement of the mandrel profile and the first profile of the body lock ring, based on a specified force applied to the housing, to adjust a downhole tool coupled to the housing from a partial set position to a fully set position.

2. The downhole tool locking system of claim 1 , wherein the carrier ring is configured to bi-directionally ride on a portion of the outer radial surface of the mandrel in response to the force applied to the housing.

3. The downhole tool locking system of claim 2 , wherein the body lock ring is adjustable from the first position engaged with the carrier ring through engagement of the carrier ring profile and the first profile of the body lock ring to a third position engaged with the carrier ring through engagement of the carrier ring profile and the first profile of the body lock ring based on adjustment of the carrier ring on the mandrel in response to the force applied to the housing, the third position comprising another partial set position of the downhole tool.

4. The downhole tool locking system of claim 1 , wherein the profile formed on the outer radial surface of the mandrel comprises a first mandrel profile, the mandrel further comprises a second mandrel profile formed on the outer radial surface of the mandrel, and the carrier ring further comprises a profile formed on an inner radial surface of the carrier ring to engage the second profile.

5. The downhole tool locking system of claim 4 , wherein the first mandrel profile is formed on a first diameter portion of the mandrel, and the second mandrel profile is formed on a second diameter portion of the mandrel, the first diameter portion of the mandrel comprising a greater mandrel wall thickness than the second diameter portion.

6. The downhole tool locking system of claim 5 , wherein the first diameter portion transitions to the first diameter portion by a no go shoulder that ramps between the first and second diameter portions.

7. The downhole tool locking system of claim 1 , further comprising a shear member that couples the carrier ring to the body lock ring, the shear member configured to shear to release the body lock ring from the carrier ring based on the specified force applied to the housing.

8. A method for setting a downhole tool, comprising:
applying a first force to a tubular housing coupled, through a body lock ring, with a carrier ring that rides on a mandrel;
adjusting the carrier ring and the body lock ring on the mandrel to a first set position based on the first force applied to the housing;
based on the carrier ring and body lock ring adjusted to the first set position, setting a downhole tool coupled to the tubular housing at a partial set location in a wellbore;
applying a second force to the tubular housing to decouple the carrier ring from the body lock ring;
adjusting the body lock ring on the mandrel to a second set position based on the second force applied to the housing; and
based on the body lock ring adjusted to the second set position, setting the downhole tool coupled to the tubular housing at a final set location in the wellbore.

9. The method of claim 8 , further comprising:
applying an intermediate force to the tubular housing coupled, through the body lock ring, with the carrier ring that rides on the mandrel; and
adjusting the carrier ring and the body lock ring on the mandrel to an intermediate set position based on the intermediate force applied to the housing.

10. The method of claim 9 , further comprising based on the carrier ring and body lock ring adjusted to the intermediate set position, setting the downhole tool coupled to the tubular housing at a second partial set location in the wellbore.

11. The method of claim 8 , wherein the carrier ring is engaged with a first portion of the mandrel in the first set position, and the body lock ring is engaged with a second portion of the mandrel in the second set position.

12. The method of claim 11 , wherein the second portion of the mandrel comprises a large diameter portion and the first portion of the mandrel comprises a small diameter portion, and the large and small diameter portions are separated by a no go shoulder on the mandrel.

13. The method of claim 11 , wherein adjusting the body lock ring on the mandrel to the second set position based on the second force applied to the housing comprises forcing the carrier ring against the no go shoulder, and adjusting the body lock ring onto the second portion of the mandrel from the carrier ring.

14. The method of claim 8 , wherein applying a second force to the tubular housing to decouple the carrier ring from the body lock ring comprises shearing a shear member that couples the carrier ring with the body lock ring.

15. The method of claim 8 , wherein at least one of the first or second forces comprises a fluid pressure of a fluid circulated in the wellbore to the tubular housing.

16. A downhole tool setting system, comprising:
a tubular member that defines a bore therethrough;
a downhole tool positioned to ride the tubular member between a partial set position and a final set position;
a locking system coupled to the downhole tool and configured to adjust the downhole tool from the partial set position based on a carrier ring moveable relative to the tubular member to the final set position based on at least a portion of the locking system affixed to the tubular member; and
a shear member that couples the carrier ring moveable relative to the tubular member to the portion of the locking system affixed to the tubular member.

17. The downhole tool setting system of claim 16 , wherein the carrier ring is configured to bi-directionally ride on a portion of the outer radial surface of the tubular member in response to a force applied to the locking system.

18. The downhole tool setting system of claim 17 , wherein the portion of the locking system affixed to the tubular member comprises a body lock ring configured to uni-directionally ride on a portion of the outer radial surface of the tubular member in response to another force applied to the locking system.

19. The downhole tool setting system of claim 16 , wherein the carrier ring is configured to uni-directionally ride on a portion of the outer radial surface of the tubular member in response to a force applied to the locking system.
