Abstract
Downhole setting systems and methods for setting downhole tools in subterranean formations. An example downhole setting system comprises a downhole setting assembly and a downhole tool configured to be set by the downhole setting assembly. The downhole setting assembly comprises a setting piston, and a mating element that physically constrains the setting piston from translating; the mating element configured to release and permit the setting piston to translate.
Claims20
A downhole setting system comprising:
- a downhole setting assembly comprising:
- a setting piston,
- a mating element that physically constrains the setting piston from translating;
- the mating element configured to release and permit the setting piston to translate;
- wherein the mating element comprises a lug, a ball, a key, or any combination thereof;
- a mandrel, wherein the mandrel comprises a slot configured to permit the mating element to move radially inward through the mandrel;
- and
- a downhole tool configured to be set by the downhole setting assembly;
- wherein the translation of the setting piston initiates the setting of the downhole tool.
6 more elements
A downhole setting assembly comprising:
- a setting piston, wherein translation of the setting piston actuates a downhole tool,
- a mating element that physically constrains the setting piston from translating prior to actuating the downhole tool;
- wherein the mating element comprises a lug, a ball, a key, or any combination thereof;
- and
- a mandrel, wherein the mandrel comprises a slot configured to permit the mating element to move radially inward through the mandrel.
2 more elements
A method of setting a packer comprising:
- introducing a packer setting tool comprising a downhole setting assembly in a wellbore, wherein the downhole setting assembly comprises:
- a setting piston, and
- a mating element that physically constrains the setting piston from translating;
- wherein the mating element comprises a lug, a ball, a key, or any combination thereof;
- the downhole setting assembly is coupled to a packer;
- a mandrel, wherein the mandrel comprises a slot configured to permit the mating element to move radially inward through the mandrel;
- and
- translating the setting piston to set the packer.
