Abstract
A treatment plug includes, an anchor runnable and settable within a structure having, at least two slips movably engaged with one another to cause the at least two slips to move radially into engagement with the structure in response to longitudinal movement between the at least two slips. The treatment plug also has at least one seal having a deformable metal member configured to radially deform into sealing engagement with the structure in response to longitudinal compression of the deformable metal member, and a seat that is sealingly receptive to a plug.
Claims23
A treatment plug comprising:
- an anchor runnable and settable within a structure having;
- at least two slips movably engaged with one another to cause the at least two slips to move radially into engagement with the structure in response to longitudinal movement between the at least two slips;
- at least one seal having a deformable metal member configured to radially deform into sealing engagement with the structure in response to longitudinal compression of the deformable metal member;
- and
- a seat that is sealingly receptive to a plug, the at least one seal being positioned longitudinally between the seat and the at least two slips thereby permitting the seal to be compressed between the slips and a plug seated against the seat.
A method of anchoring and sealing a treatment plug to a structure, comprising:
- longitudinally moving a first half of a plurality of slips relative to a second half of the plurality of slips;
- altering a radial dimension defined by the plurality of slips;
- anchoring the plurality of slips to a structure;
- longitudinally compressing at least one deformable member;
- sealingly engaging the structure with the at least one deformable member;
- building pressure against a plug seated at a seat of the treatment plug positioned in a direction upstream of the deformable member, the deformable member being positioned in a position upstream of the plurality of the slips, upstream being defined by pressure causing the plug to seat;
- and
- compressing the deformable member between the plugged seat and the anchored plurality of slips.
