Abstract
A downhole triggering tool includes a tool-engaging portion movable from a first position to a second position under the action of an external force, and a release mechanism for selectively permitting movement of the tool-engaging portion from the first position to the second position, the tool-engaging portion is restrained against the external force by the release mechanism through a force reducing mechanism.
Claims23
A downhole triggering tool, comprising:
- a tool-engaging portion movable from a first position to a second position under the action of an external force;
- and
- a release mechanism for selectively permitting movement of the tool-engaging portion from the first position to the second position, the tool engaging portion being restrained against the external force by the release mechanism through a force reducing mechanism.
A downhole tool, comprising:
- a setting tool comprising a fluid actuated piston arrangement in selective fluid communication with a fluid source, and a downhole tool-engaging portion;
- and
- a triggering tool comprising a setting tool-engaging portion movable from a first position to prevent fluid communication between the fluid source and piston arrangement of the setting tool, and a second position to permit fluid communication between the fluid source and piston arrangement, wherein the setting tool-engaging portion is moved under the action of an external force, the triggering tool further comprising a release mechanism for selectively permitting movement of the setting tool-engaging portion from the first position to the second position, the external force being transmitted to the release mechanism via a force reducing mechanism.
