Abstract
Provided is a sealing/anchoring assembly, a well system, and a method. The sealing/anchoring assembly, in one aspect, includes a mandrel, a sealing/anchoring element positioned about the mandrel, and a setting sleeve coupled with a first end of the sealing/anchoring element. The sealing/anchoring assembly, in one aspect, further includes an internally threaded setting sleeve coupled with a second end of the sealing/anchoring element, the internally threaded setting sleeve configured to employ its internal threads to rotate and axially translate along the mandrel to move the sealing/anchoring element between a radially retracted state a radially expanded state.
Claims26
A sealing/anchoring assembly, comprising:
- a mandrel;
- a sealing/anchoring element positioned about the mandrel;
- a setting sleeve coupled with a first end of the sealing/anchoring element;
- and
- an internally threaded setting sleeve coupled with a second end of the sealing/anchoring element, the internally threaded setting sleeve configured to employ its internal threads to rotate and axially translate along the mandrel to move the sealing/anchoring element between a radially retracted state a radially expanded state.
A well system, comprising:
- a wellbore located in a subterranean formation;
- and
- a sealing/anchoring assembly positioned in the wellbore, the sealing/anchoring assembly including:
- a mandrel;
- a sealing/anchoring element positioned about the mandrel;
- a setting sleeve coupled with a first end of the sealing/anchoring element;
- and
- an internally threaded setting sleeve coupled with a second end of the sealing/anchoring element, the internally threaded setting sleeve configured to employ its internal threads to rotate and axially translate along the mandrel to move the sealing/anchoring element between a radially retracted state a radially expanded state.
A method, comprising:
- positioning a sealing/anchoring assembly within a wellbore located in a subterranean formation, the sealing/anchoring assembly including:
- a mandrel;
- a sealing/anchoring element positioned about the mandrel;
- a setting sleeve coupled with a first end of the sealing/anchoring element;
- and
- an internally threaded setting sleeve coupled with a second end of the sealing/anchoring element, the internally threaded setting sleeve configured to employ its internal threads to rotate and axially translate along the mandrel to move the sealing/anchoring element between a radially retracted state a radially expanded state;
- coupling a rotary motor with the internally threaded setting sleeve;
- and
- actuating the rotary motor to rotate and axially translate the internally threaded setting sleeve to move the sealing/anchoring element from the radially retracted state to the radially expanded state.
