Abstract

A downhole tool having a mandrel, with a fingered member and a conical member being disposed around the mandrel. There is a solid-body insert positioned proximately to each of the fingered member and the first conical member. The fingered member comprises a plurality of fingers configured to move from a first position to a second position.

Claims (59)

1. A downhole tool comprising:

a mandrel comprising:

a proximate end, a distal end, an outer mandrel surface, a flowbore extending through an entire length of the mandrel from the proximate end to the distal end, and a set of threads on the outer mandrel surface at the distal end;

a fingered member disposed around the mandrel;

a first conical member also disposed around the mandrel; and

an insert disposed around, but not engaged with the mandrel, the insert also positioned proximate to the fingered member and the first conical member, and in engagement with an end of the fingered member; and

a lower sleeve threadingly engaged with the set of threads,

wherein the insert comprises a solid circular body, a first end, a second end,

wherein the fingered member comprises a plurality of fingers, and wherein one or more ends of the plurality of fingers comprises an outer tapered surface.

2. The downhole tool of claim 1 , the tool further comprising:

a first slip;

a second slip;

a bearing plate;

a second conical member; and

a sealing element.

3. The downhole tool of claim 1 , wherein one or more components of the tool are made from a material comprising one or more of filament wound material, fiberglass cloth wound material, and molded fiberglass composite.

4. The downhole tool of claim 1 , wherein the mandrel further comprises a ball seat formed therein.

5. A downhole tool comprising:

a mandrel made of composite material;

a fingered member disposed around the mandrel; and

a first conical member also disposed around the mandrel and proximate to an end of the fingered member,

an insert disposed around, but not engaged with the mandrel, the insert also positioned proximate to each of the fingered member and the first conical member,

a first slip;

a second slip;

a bearing plate;

a second conical member;

a sealing element; and

a lower sleeve threadingly engaged with the mandrel,

wherein the insert comprises a solid circular body, a first end, a second end,

wherein the fingered member comprises a plurality of fingers.

6. The downhole tool of claim 5 , wherein one or more ends of the plurality of fingers comprises an outer tapered surface, and wherein at least one of the first slip and the second slip further comprise: a metal slip configured with a one-piece circular slip body comprising at least one longitudinal hole.

7. The downhole tool of claim 6 , wherein one or more components of the tool are made from a material comprising one or more of filament wound material, fiberglass cloth wound material, and molded fiberglass composite, wherein the mandrel further comprises: a distal end having a first outer diameter; a proximate end having a second outer diameter; and an outer mandrel surface, and wherein the outer mandrel surface at the distal end is configured with a set of threads.

8. The downhole tool of claim 5 , wherein the mandrel further comprises:

a proximate end, a distal end, an outer mandrel surface, a flowbore extending through an entire length of the mandrel from the proximate end to the distal end, and a set of threads on the outer mandrel surface at the distal end.

9. The downhole tool of claim 8 , wherein the mandrel further comprises a ball seat formed therein.

10. A method for performing a downhole operation in a tubular, the method comprising:

running a downhole tool through a first portion of the tubular, wherein the downhole tool comprises:

a mandrel comprising one or more sets of threads;

a fingered member disposed around the mandrel;

a first conical shaped member also disposed around the mandrel; and

an insert disposed around, but not engaged with the mandrel, the insert also positioned proximate to the fingered member and the first conical shaped member,

a first slip;

a second slip;

a bearing plate;

a second conical member;

a sealing element; and

a lower sleeve threadingly engaged with the mandrel,

wherein the fingered member comprises a plurality of fingers configured to move from an initial position to a set position, wherein at least one of the first slip and the second slip further comprise: a metal slip configured with a one-piece circular slip body comprising at least one longitudinal hole, and wherein the insert comprises a solid circular body, a first end, and a second end;

continuing to run the downhole tool until arriving at a position within a second portion of the tubular; and

setting the downhole tool within the second portion,

wherein the first portion comprises a first inner diameter that is smaller than a second inner diameter of the second portion.

11. The method of claim 10 , wherein the insert is made of polyether ether ketone.

12. The method of claim 10 , wherein the fingered member comprises an outer surface, and an inner surface, and wherein a first groove is disposed within the outer surface, and wherein a second groove is disposed within the inner surface.

13. The method of claim 12 , wherein one or more components of the tool are made from a material comprising one or more of filament wound material, fiberglass cloth wound material, and molded fiberglass composite.

14. The method of claim 10 , wherein the mandrel further comprises: a distal end having a first outer diameter; a proximate end having a second outer diameter; and a mandrel outer surface configured with a set of threads.

15. The method of claim 14 , wherein one or more ends of the plurality of fingers comprises an outer tapered surface.

16. The method of claim 10 , wherein the mandrel further comprises:

a proximate end, a distal end, an outer mandrel surface, and a flowbore extending through an entire length of the mandrel from the proximate end to the distal end.

17. The method of claim 10 , wherein the mandrel further comprises a ball seat formed therein.
