Abstract

A tubular includes an outer surface, an inner surface defining a passage, and a plurality of openings extending through the outer surface and the inner surface. A sleeve is positioned within the passage. The sleeve includes an outer surface portion having at least one recess. At least one release member extends from the inner surface into the at least one recess. The at least one release member maintains the sleeve in a first configuration relative to the plurality of openings. At least one of the inner surface and the outer surface portion includes a self-holding connection that establishes one of a reduced diameter portion of the passage and an increased diameter portion of the sleeve. The self-holding connection is configured to maintain the sleeve in a second configuration axially shifted relative to the first configuration.

First claim

What is claimed is:

1. A tubular comprising:
an outer surface, an inner surface defining a passage, and a plurality of openings extending through the outer surface and the inner surface, the inner surface including an annular recess;
a sleeve positioned within the passage, the sleeve including a first end, a second end, and an intermediate portion having an outer surface portion extending between the first end and the second end, the outer surface including at least one recess, the sleeve further including a pressure relief orifice spaced from the second end and an annular rib projecting radially outwardly of the outer surface between the second end and the pressure relief orifice, wherein the annular projection selectively nests within the annular recess to establish a self-holding connection; and
at least one release member extending from the inner surface into the at least one recess, the at least one release member maintaining the sleeve in a first configuration relative to the plurality of openings, wherein the self-holding connection is configured to axially and rotationally maintain the sleeve in a second configuration axially shifted relative to the first configuration.

2. The tubular according to claim 1 , wherein the first end of the sleeve includes a ball seat.

3. The tubular according to claim 1 , wherein the self-holding connection further includes a Morse taper formed at the second end of the sleeve.

4. The tubular according to claim 1 , wherein the self-holding connection further includes a first containment feature defining an increased diameter portion of the sleeve and a second containment feature defining a reduced diameter portion of the passage.

5. The tubular according to claim 4 , wherein the tubular includes a first tubular member joined to a second tubular member, the openings being formed in the first tubular member and the second containment feature being formed in the second tubular member.

6. The tubular according to claim 1 , further comprising: at least one seal extending about the sleeve.

7. The tubular according to claim 1 , wherein the at least one release member comprises a shear screw.

8. A downhole system comprising:
a first system; and
a second system fluidically connected to the first system through one or more tubulars, at least one of the one or more tubulars comprising:
an outer surface, an inner surface defining a passage, and a plurality of openings extending through the outer surface and the inner surface, the inner surface including an annular recess;
a sleeve positioned within the passage, the sleeve including a first end, a second end, and an intermediate portion having an outer surface portion extending between the first end and the second end, the outer surface including at least one recess, the sleeve further including a pressure relief orifice spaced from the second end and an annular rib projecting radially outwardly of the outer surface between the second end and the pressure relief orifice, wherein the annular projection selectively nests within the annular recess to establish a self-holding connection; and
at least one release member extending from the inner surface into the at least one recess, the at least one release member maintaining the sleeve in a first configuration relative to the plurality of openings, wherein the self-holding connection is configured to axially and rotationally maintain the sleeve in a second configuration axially shifted relative to the first configuration.

9. The downhole system according to claim 8 , wherein the first end includes a ball seat.

10. The downhole system according to claim 8 , wherein the self-holding connection further includes a Morse taper formed at the second end of the sleeve.

11. The downhole system according to claim 8 , wherein the self-holding connection further includes a first containment feature defining an increased diameter portion of the sleeve and a second containment feature defining a reduced diameter portion of the passage.

12. The downhole system according to claim 11 , wherein the tubular includes a first tubular member joined to a second tubular member, the openings being formed in the first tubular member and the second containment feature being formed in the second tubular member.

13. The downhole system according to claim 8 , further comprising: at least one seal extending about the sleeve.

14. The downhole system according to claim 8 , wherein the at least one release member comprises a shear screw.
