Abstract

A downhole tool includes a sleeve having a first end and a second end, a slip assembly coupled to the second end of the sleeve, a first cone positioned at least partially in the sleeve, proximal to the first end thereof, and a second cone positioned at least partially in the slip assembly. The first and second cones are configured to be moved toward one another from a run-in configuration to a set configuration. When actuating from the run-in configuration to the set configuration, the sleeve is forced radially outward by the first cone. When actuating from the run-in configuration to the set configuration, the slip assembly is forced radially outward by the second cone.

First claim

What is claimed is:

1. A downhole tool, comprising:
a sleeve having a first end and a second end;
a slip assembly coupled to the second end of the sleeve;
a first cone positioned at least partially in the sleeve, proximal to the first end thereof; and
a second cone positioned at least partially in the slip assembly,
wherein the first and second cones are configured to be moved toward one another from a run-in configuration to a set configuration,
wherein, when actuating from the run-in configuration to the set configuration, the sleeve is forced radially outward by the first cone,
wherein, when actuating from the run-in configuration to the set configuration, the slip assembly is forced radially outward by the second cone, and
wherein, when the second cone is moved toward the set configuration, the second cone forces the slip assembly axially toward the second end of the sleeve.

2. The downhole tool of claim 1 , wherein the slip assembly comprises a plurality of slip segments disposed circumferentially adjacent to one another, and wherein, when the second cone is moved toward the set configuration, the second cone separates the plurality of slip segments circumferentially apart from one another.

3. The downhole tool of claim 1 , wherein the first cone forces the sleeve radially outwards from the run-in configuration to the set configuration, and wherein the sleeve in the set configuration forms at least a partial seal with a surrounding tubular.

4. The downhole tool of claim 1 , wherein the slip assembly comprises a plurality of inserts configured to be at least partially embedded into a surrounding tubular when the downhole tool is in the set configuration.

5. The downhole tool of claim 1 , wherein the slip assembly comprises a grit coating on an outside surface thereof, the grit coating configured to engage a surrounding tubular when the downhole tool is in the set configuration.

6. The downhole tool of claim 1 , wherein the sleeve is made from a first material, and the slip assembly is made from a second material, the first and second materials being configured to dissolve at different rates in a well.

7. The downhole tool of claim 1 , further comprising a connection member extending between and connecting together the second end of the sleeve and the slip assembly, wherein the connection member is configured to break apart when the downhole tool is moved into the set configuration.

8. The downhole tool of claim 1 , further comprising a retaining member extending around the slip assembly, wherein the retaining member is configured to break apart when the downhole tool is actuated into the set configuration.

9. The downhole tool of claim 8 , wherein the retaining member comprises a grit coating on an outside surface thereof.

10. The downhole tool of claim 1 , wherein the first cone comprises one or more inserts at least partially embedded therein and extending outwards therefrom so as to provide a wear surface for engaging a surrounding tubular when running the downhole tool into a well.

11. The downhole tool of claim 10 , wherein the one or more inserts of the first cone lack a cutting edge, such that the one or more inserts are configured to avoid damaging an inside surface of the sleeve during setting when the first cone, including the one or more inserts, moves fully into the sleeve.

12. The downhole tool of claim 1 , wherein the second cone defines a plurality of bores extending therethrough.

13. A downhole tool, comprising:
a sleeve having a first end and a second end;
a slip assembly coupled to the second end of the sleeve;
a first cone positioned at least partially in the sleeve, proximal to the first end thereof; and
a second cone positioned at least partially in the slip assembly,
wherein the first and second cones are configured to be moved toward one another from a run-in configuration to a set configuration;
a connection member extending between and connecting together the second end of the sleeve and the slip assembly, wherein the connection member is configured to break apart when the downhole tool is moved into the set configuration,
wherein, when actuating from the run-in configuration to the set configuration, the sleeve is forced radially outward by the first cone,
wherein, when actuating from the run-in configuration to the set configuration, the slip assembly is forced radially outward by the second cone,
wherein the connection member at least partially defines a gap between the second end of the sleeve and the slip assembly, and
wherein, the slip assembly moves axially toward the second end of the sleeve when the downhole tool is in the set configuration thereby substantially closing the gap.

14. A downhole tool, comprising:
a sleeve having a first end and a second end;
a slip assembly coupled to the second end of the sleeve;
a first cone positioned at least partially in the sleeve, proximal to the first end thereof; and
a second cone positioned at least partially in the slip assembly,
wherein the first and second cones are configured to be moved toward one another from a run-in configuration to a set configuration,
wherein, when actuating from the run-in configuration to the set configuration, the sleeve is forced radially outward by the first cone,
wherein, when actuating from the run-in configuration to the set configuration, the slip assembly is forced radially outward by the second cone, and
wherein the slip assembly is configured to pivot toward the sleeve when the first and second cones are moved to the set configuration.

15. A downhole tool, comprising:
a sleeve having a first end and a second end;
a slip assembly coupled to the second end of the sleeve;
a first cone positioned at least partially in the sleeve, proximal to the first end thereof; and
a second cone positioned at least partially in the slip assembly,
wherein the first and second cones are configured to be moved toward one another from a run-in configuration to a set configuration,
wherein, when actuating from the run-in configuration to the set configuration, the sleeve is forced radially outward by the first cone,

wherein, when actuating from the run-in configuration to the set configuration, the slip assembly is forced radially outward by the second cone, and
wherein the downhole tool further comprising a retaining member extending around the slip assembly, wherein the retaining member is configured to break apart when the downhole tool is actuated into the set configuration, wherein the retaining member comprises one or more inserts at least partially embedded therein and extending outwards therefrom so as to provide a wear surface for engaging a surrounding tubular when running the downhole tool into a well.

16. A downhole assembly, comprising:
a downhole tool comprising:
a sleeve having a first end and a second end;
a slip assembly coupled to the second end of the sleeve;
a first cone positioned at least partially in the sleeve, proximal to the first end thereof, the first cone defining a valve seat; and
a second cone positioned at least partially in the slip assembly,
wherein the first and second cones are configured to be moved toward one another from a run-in configuration to a set configuration,
wherein, when actuating from the run-in configuration to the set configuration, the sleeve is forced radially outward by the first cone, and
wherein, when actuating from the run-in configuration to the set configuration, the slip assembly is forced radially outward by the second cone;

a setting tool comprising:
a setting sleeve configured
