Downhole Swaging Tool Adaptive Dimension Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing downhole tools, such as hangers and packers, often fail to be reliably set due to inadequate setting forces from the swaging process, which can lead to tool failure.
Innovation Solution
A downhole swaging system featuring a tubular with an area of strength that varies in resistance to swaging, paired with a swaging tool having a first swage with a fixed dimension and a second swage with an adjustable dimension that adjusts in response to changes in resistance, ensuring effective setting and expansion of the tubular.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed dimension swaging tool is used, then the device complexity is reduced, but the setting force is inadequate to reliably set the tool
Solution Approach 1:
The swaging tool transitions from a fixed dimension to an adjustable dimension configuration. The second swage's dimension is dynamically adjusted in response to resistance changes encountered during the swaging process, allowing the tool to adapt to varying tubular properties and ensure reliable setting.
Solution Approach 2:
The system incorporates feedback mechanisms where resistance changes detected during swaging trigger automatic adjustment of the second swage dimension. This closed-loop control ensures the tool maintains optimal setting force throughout the process, improving reliability without requiring complex manual intervention.
2Force
If the swaging dimension is adjusted in response to resistance changes, then the setting force is improved, but the device complexity increases
Solution Approach 1:
The swaging tool is divided into two distinct swages: a first swage with a fixed dimension and a second swage with an adjustable dimension. This segmentation allows each component to perform a specific function - the first swage performs initial swaging while the second swage provides adaptive force adjustment, distributing complexity across modular components.
Solution Approach 2:
The system changes the dimensional parameter of the second swage in response to resistance changes during swaging. By dynamically adjusting this physical parameter, the tool optimizes setting force to match the actual conditions encountered, improving performance without requiring complete redesign of the entire system.
3Reliability
If a two-stage adjustable swaging tool is used, then the tool setting reliability is improved, but the manufacturing complexity increases
Solution Approach 1:
The complex two-stage adjustable tool is manufactured as separate modular components - the first fixed swage and the second adjustable swage. This segmentation simplifies manufacturing by allowing each component to be produced independently using optimized processes, then assembled into the complete tool system.
Solution Approach 2:
The first swage with fixed dimension serves as a universal initial swaging element that can be used across different applications, while the second swage provides the specialized adjustable functionality. This multi-functionality approach allows the system to achieve high reliability through the combination of simple universal components and one adjustable element.

AI summary
A downhole swaging system includes, a tubular having an area of strength with a different resistance to swaging as compared to areas of the tubular outside of the area of strength, and a swaging tool. The swaging tool has a first swage, and a second swage with an adjustable swaging dimension, the second swage is in functional communication with the first swage such that the adjustable swaging dimension is adjusted in response to the first swage encountering a change in resistance to swaging.
