Abstract
A method having the following steps: running a circulation valve comprising a reactive material into the well bore on the casing; reverse-circulating an activator material in the well bore until the activator material contacts the reactive material of the circulation valve; reconfiguring the circulation valve by contact of the activator material with the reactive material; and reverse-circulating a cement composition in the well bore until the reconfigured circulation valve decreases flow of the cement composition. A circulation valve for cementing casing in a well bore, the valve having: a valve housing connected to the casing and comprising a reactive material; a plurality of holes in the housing, wherein the plurality of holes allow fluid communication between an inner diameter of the housing and an exterior of the housing, wherein the reactive material is expandable to close the plurality of holes.
Claims (10)
1. A packer for cementing casing in a well bore wherein an annulus is defined between the casing and the well bore, the system comprising:
a packer element connected to the casing, wherein the packer element allows fluid to pass through the a well bore annulus past the packer element when it is in a non-expanded configuration, and wherein the packer element restricts fluid passage in the annulus past the packer element when the packer element is expanded;
an expansion device in communication with the packer element, and a lock that prevents the expansion device from expanding the packer element, wherein the lock comprises a reactive material.
a packer element connected to the casing, wherein the packer element allows fluid to pass through the a well bore annulus past the packer element when it is in a non-expanded configuration, and wherein the packer element restricts fluid passage in the annulus past the packer element when the packer element is expanded;
an expansion device in communication with the packer element, and a lock that prevents the expansion device from expanding the packer element, wherein the lock comprises a reactive material.
2. A packer as claimed in claim 1, wherein the reactive material of said lock comprises an expandable material that expands by contact with an activator material, wherein the lock becomes unlocked upon expansion of the expandable material.
3. A packer as claimed in claim 1, wherein the reactive material of said lock comprises a shrinkable material that shrinks by contact with an activator material, wherein the lock becomes unlocked upon shrinkage of the shrinkable material.
4. A packer as claimed in claim 1, wherein the reactive material of said lock comprises a dissolvable material that dissolves by contact with an activator material, wherein the lock becomes unlocked upon dissolution of the dissolvable material.
5. A packer as claimed in claim 1, further comprising a protective material that coats the reactive material, wherein the protective material is readable by an activator material to expose the reactive material to a well bore fluid, whereby the lock becomes unlocked upon exposure of the reactive material to the well bore fluid.
6. A packer as claimed in claim 5, wherein the reactive material unlocks the lock upon contact with a well bore fluid selected from the group of fluids consisting of water, drilling mud, circulation fluid, fracturing fluid, cement composition, fluid leached into the well bore from a formation, and activator material.
7. A packer as claimed in claim 5, wherein the reactive material of said lock comprises an expandable material that expands by contact with a well bore fluid, wherein the lock becomes unlocked upon expansion of the expandable material.
8. A packer as claimed in claim 5, wherein the reactive material of said lock comprises a shrinkable material that shrinks by contact with a well bore fluid, wherein the lock becomes unlocked upon shrinkage of the shrinkable material.
9. A packer as claimed in claim 5, wherein the reactive material of said lock comprises a dissolvable material that dissolves by contact with a well bore fluid, wherein the lock becomes unlocked upon dissolution of the dissolvable material.
10. A packer as claimed in claim 1, further comprising an isolation valve.
