Wellbore assembly with an accumulator system for actuating a setting tool
A wellbore assembly includes a conveyance member including at least one of a continuous spooled rod, a wireline, and a slickline; an accumulator system connected to the conveyance member; and a setting tool connected to the accumulator system. The accumulator system may be configured to supply a fluid pressure to actuate the setting tool. A method of operating a wellbore tool includes lowering a wellbore assembly into a wellbore using a conveyance member including at least one of a continuous spooled rod, a wireline, and a slickline, wherein the wellbore assembly includes an accumulator system and a setting tool. The method includes actuating the accumulator system to provide a fluid pressure to the setting tool. The method also includes actuating the setting tool using the fluid pressure.
1. A wellbore assembly, comprising:
an accumulator system connected to a conveyance member, wherein the accumulator system includes a first reactant, a second reactant, a first chamber, a piston, and a conduit; and
a setting tool connected to the accumulator system, the setting tool having an interior in fluid communication with the first chamber via the conduit, wherein:
the piston is responsive to an externally-supplied force to combine the first reactant and the second reactant in the first chamber and generate a rapid increase in fluid pressure in the first chamber, and
the increased fluid pressure flows from the first chamber and through the conduit to the interior of the setting tool to actuate the setting tool.
2. The assembly of claim 1 , wherein the first reactant and the second reactant include at least one of a liquid component, a solid component, and a gaseous component.
3. The assembly of claim 1 , wherein the first reactant and the second reactant are pre-filled in the accumulator system.
4. The assembly of claim 1 , further comprising:
a second chamber; and
a valve disposed between the first chamber and the second chamber.
5. The assembly of claim 4 , wherein the second chamber contains the second reactant.
6. The assembly of claim 4 , wherein the valve is a rupture disk.
7. The assembly of claim 1 , wherein the conveyance member includes at least one of a continuous spooled rod, a wireline, and a slickline.
8. The assembly of claim 1 , further comprising a second chamber containing the first reactant.
9. The assembly of claim 1 , wherein the first reactant includes a plurality of components, the plurality of components separated by one or more non-reactive components.
10. The assembly of claim 1 , further comprising a piston member disposed in the accumulator system, the piston member including a plurality of chambers.
11. The assembly of claim 10 , wherein:
each of the plurality of chambers includes a component of the first reactant;
the piston member is movable to sequentially expose each of the plurality of chambers.
12. The assembly of claim 1 , wherein the externally-supplied force is provided by one of the conveyance member, a weight stem, or a hydraulic pressure.
13. A method of operating a wellbore tool, comprising:
lowering a wellbore assembly into a wellbore using a conveyance member, wherein the wellbore assembly includes an accumulator system and a setting tool;
moving a piston of the accumulator system by applying an externally-supplied force on the piston, thereby mixing a first reactant with a second reactant in a chamber of the accumulator system to generate a reaction;
generating a rapid increase in fluid pressure in the chamber from the reaction;
causing the increased fluid pressure to flow from the chamber through a conduit of the accumulator system to an interior of the setting tool to actuate the setting tool which actuates the wellbore tool; and
operating the wellbore tool.
14. The method of claim 13 , wherein the first reactant and the second reactant include at least one of a liquid component, a solid component, and a gaseous component.
15. The method of claim 13 , further comprising pre-filling the first reactant and the second reactant in the accumulator system.
16. The method of claim 13 , further comprising mixing the first reactant and the second reactant to generate additional reactions.
17. The method of claim 13 , further comprising moving a piston member to mix the first reactant and the second reactant.
18. The method of claim 17 , wherein the piston member includes a plurality of chambers.
19. The method of claim 13 , further comprising rupturing a disk valve to mix the first reactant and the second reactant.
20. The method of claim 13 , further comprising wherein the first reactant includes a plurality of components.
21. The method of claim 13 , wherein the externally-supplied force is provided by one of the conveyance member, a weight stem, or a hydraulic pressure.
22. A wellbore assembly, comprising:
an accumulator system connected to a conveyance member, wherein the accumulator system includes a first reactant, a second reactant, a first chamber, and a piston; and
a setting tool connected to the accumulator system, the setting tool having an interior in fluid communication with the first chamber via a conduit, wherein:
the accumulator system is configured to drive the piston to push at least one of the first reactant and the second reactant into the first chamber to combine the first reactant and the second reactant in the first chamber and generate a rapid increase in fluid pressure in the first chamber,
the increased fluid pressure flows from the first chamber to the interior of the setting tool to actuate the setting tool.
