Integrated Downhole Setting Tool for Reliable Tool Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for efficient techniques to reliably set and activate downhole tools in harsh and compact downhole environments.
Innovation Solution
A setting tool with an integrated igniter is used to activate downhole components by igniting a propellant, which generates ignition fluid to move the deployment portion and the connected downhole component to an activated position, allowing for reliable deployment in challenging downhole conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate igniter and setting tool are used, then the downhole tool can be activated, but the device complexity and assembly time increase
Solution Approach 1:
The patent combines the igniter and setting tool into a single integrated assembly where the igniter is positioned within the setting tool housing. This integration eliminates the need for separate handling and assembly of two distinct components, reducing overall device complexity while maintaining reliable activation functionality through the unified structure.
Solution Approach 2:
The integrated assembly serves multiple functions simultaneously: the igniter provides initiation capability while the setting tool provides the setting mechanism. This multi-functional design reduces the number of separate components needed, simplifying the overall system while ensuring both ignition and setting operations can be performed reliably.
2Productivity
If traditional setting tools are used in harsh downhole environments, then the tools can operate, but reliability and efficiency decrease
Solution Approach 1:
The igniter is pre-positioned within the setting tool housing before deployment, ensuring proper alignment and readiness for immediate activation. This preliminary configuration eliminates setup time and potential misalignment issues in harsh downhole environments, improving both activation efficiency and reliability.
Solution Approach 2:
The integrated design allows the setting tool to self-activate through the incorporated igniter system, eliminating the need for separate activation mechanisms or additional equipment. This self-contained capability ensures reliable operation in remote downhole conditions where external assistance may be limited.
3Device complexity
If the igniter is integrated into the setting tool, then device complexity is reduced, but manufacturing complexity increases
Solution Approach 1:
The integrated assembly is designed with modular components that can be manufactured separately and then assembled. The igniter and setting tool housing are distinct elements that can be produced using standard manufacturing processes, then combined through conventional assembly techniques, balancing integration benefits with manufacturing feasibility.

AI summary
A setting tool fora downhole tool includes a setting housing, a setting assembly, and an integrated igniter. The setting housing has a passage therethrough. The setting assembly is positioned in the passage, and includes a drive portion and a deployment portion. The drive portion has an elongate body with a propellant chamber. The deployment portion has an opening defining a drive cavity shaped to slidingly receive an end of the drive portion. The deployment portion includes a deployment end connectable to the downhole component. The integrated igniter is positioned in the propellant chamber, and includes an integrator housing, an internal propellant, and a switch assembly connected to the internal propellant. Upon triggering the switch, the internal propellant is ignited to release an ignition fluid under ignition pressure to move the deployment portion and the downhole component connected thereto to an activated position.
