초록 ▼

Apparatuses for restricting fluid flow through a well conduit comprise a tubular member having a seat member disposed within the tubular member for receiving a plug element. One or both of the seat member or the plug element comprise at least one shape-memory material to facilitate the plug element being able to land on the seat and/or to facilitate the plug element to pass through a seat member or other restriction in the tubular member either before or after landing on a seat.

대표청구항 ▼

1. An apparatus for restricting flow through a conduit, the apparatus comprising: a housing having a longitudinal bore and a seat member disposed within the bore, the seat member comprising a shape-memory material that is moveable between a first shape for receiving a plug element to restrict fluid flow through the longitudinal bore and a second shape for passage of the plug element through the seat member in response to at least one stimulus selected from the group consisting of temperature, electromagnetic field, acidity, chemical solution and light. 2. The apparatus of claim 1, wherein the seat member is biased toward the second shape by the shape-memory material. 3. The apparatus of claim 1, wherein the seat member is biased toward the first shape by the shape-memory material. 4. An apparatus for restricting flow through a conduit, the apparatus comprising: a housing having a longitudinal bore and a seat disposed within the bore for receiving a plug element to restrict fluid flow through the longitudinal bore, the plug element comprising a shape-memory material that is moveable between a first shape for landing on the seat to restrict fluid flow through the longitudinal bore and a second shape for passage of the plug element through the seat member in response to at least one stimulus selected from the group consisting of temperature, electromagnetic field, acidity, chemical solution and light; andwherein the plug element is biased toward the second shape by the shape-memory material. 5. A method of restricting fluid flow through a tubular member, the method comprising the steps of: (a) transporting a plug element through a longitudinal bore of a tubular member;(b) landing the plug element on a seat disposed within the tubular member causing restriction of fluid flow through the seat, the seat comprising a shape-memory material that is moveable between a non-operational shape and an operational shape in response to at least one stimulus selected from the group consisting of temperature, electromagnetic field, acidity, chemical solution and light, the operational shape allowing the plug element to land on the seat to restrict fluid flow through the tubular member;(c) moving the seat from the operational shape toward the non-operational shape and transporting the plug element through the seat;(d) returning the seat to the operational shape by activation of the shape-memory material of the seat; and(e) repeating steps (a) and (b). 6. The method of claim 5, wherein prior to step (b), the seat is contacted with the stimulus to retain the seat in the operational shape. 7. The method of claim 5, wherein during step (d), the stimulus is contacted with the seat. 8. A method of restricting fluid flow through a tubular member, the method comprising the steps of: (a) transporting a plug element through a longitudinal bore of a tubular member, the plug element comprising a shape memory material and moveable between a non-operational shape and an operational shape in response to at least one stimulus selected from the group consisting of temperature, electromagnetic field, acidity, chemical solution and light, the operational shape allowing the plug element to land on a seat disposed within the tubular member to restrict fluid flow through the tubular member;(b) landing the plug element on the seat causing restriction of fluid flow through the seat;(c) moving the plug element from the operational shape to the non-operational shape and transporting the plug element through the seat; and(d) returning the plug element to the operational shape by activation of the shape-memory material of the plug element. 9. The method of claim 8, wherein the stimulus is contacted with the plug element during step (d). 10. The method of claim 8, wherein during step (c), the plug element is contacted with the stimulus to move the plug element from the operational shape to the non-operational shape.
