Abstract
A sealing assembly, a well system, and a method. The sealing assembly, in one aspect, includes a mandrel, and a sealing element positioned about the mandrel. The sealing element, in this aspect, includes a first sealing element portion and a second sealing element portion, and a deployable spacer positioned between the first sealing element portion and the second sealing element portion. The sealing assembly, according to this aspect, further includes a first collar sleeve coupled proximate a first end of the sealing element, and a second collar sleeve coupled proximate a second end of the sealing element.
Claims27
A sealing assembly, comprising:
- a mandrel;
- a sealing element positioned about the mandrel, the sealing element including:
- a first sealing element portion and a second sealing element portion;
- and
- a deployable spacer positioned between the first sealing element portion and the second sealing element portion;
- a first collar sleeve coupled proximate a first end of the sealing element;
- and
- a second collar sleeve coupled proximate a second end of the sealing element, wherein the first and second collar sleeves are configured to axially translate relative to one another along the mandrel to move the sealing element between a radially retracted state a radially expanded state, and further wherein the deployable spacer is configured to at least partially radially deploy from an undeployed state to a deployed state as the sealing element moves from the radially retracted state to the radially expanded state.
A well system, comprising:
- a wellbore located in a subterranean formation;
- and
- a sealing assembly positioned in the wellbore, the sealing assembly including:
- a mandrel;
- a sealing element positioned about the mandrel, the sealing element including:
- a first sealing element portion and a second sealing element portion;
- and
- a deployable spacer positioned between the first sealing element portion and the second sealing element portion;
- a first collar sleeve coupled proximate a first end of the sealing element;
- and
- a second collar sleeve coupled proximate a second end of the sealing element, wherein the first and second collar sleeves are configured to axially translate relative to one another along the mandrel to move the sealing element between a radially retracted state a radially expanded state, and further wherein the deployable spacer is configured to at least partially radially deploy from an undeployed state to a deployed state as the sealing element moves from the radially retracted state to the radially expanded state.
A method, comprising:
- positioning a sealing assembly within a wellbore located in a subterranean formation, the sealing assembly including:
- a mandrel;
- a sealing element positioned about the mandrel, the sealing element including:
- a first sealing element portion and a second sealing element portion;
- and
- a deployable spacer positioned between the first sealing element portion and the second sealing element portion;
- a first collar sleeve coupled proximate a first end of the sealing element;
- and
- a second collar sleeve coupled proximate a second end of the sealing element, wherein the first and second collar sleeves are configured to axially translate relative to one another along the mandrel to move the sealing element between a radially retracted state a radially expanded state, and further wherein the deployable spacer is configured to at least partially radially deploy from an undeployed state to a deployed state as the sealing element moves from the radially retracted state to the radially expanded state;
- and
- moving the sealing element from the radially retracted state to the radially expanded state, the moving causing the deployable spacer to deploy from the undeployed state to the deployed state.
