Downhole Tool Cyclical Loading Frequency Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Downhole tools with cyclical characteristics face operational limitations due to resonant frequencies that create detrimental forces, affecting their performance and lifespan, and existing methods lack effective means to optimize these tools in real-time.
Innovation Solution
A system and methodology that involves sampling cyclical activity at a frequency greater than the cyclical activity to collect detailed data, allowing for adjustments such as changing the frequency or magnitude of the cyclical loading to improve tool operation, using high-rate measurements and real-time processing to optimize tool performance and prevent operational limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the tool operates at resonant frequency to optimize performance, then the reach and effectiveness of the tool is improved, but detrimental forces are created that limit operation and lifespan
Solution Approach 1:
The system dynamically adjusts the cyclical loading frequency based on real-time monitoring of tool response and accumulated cycling data. The frequency is modified to maintain optimal performance while avoiding resonant conditions that cause detrimental forces, allowing the tool to adapt its operating parameters during deployment
Solution Approach 2:
The system implements feedback by monitoring the cyclical activity at a frequency greater than the cyclical activity itself, using this data to detect when resonant frequencies are approached, and automatically adjusting operating parameters to prevent detrimental forces while maintaining tool effectiveness
2Reliability
If cyclical activity is monitored and adjusted in real-time, then tool operation is optimized and lifespan extended, but data processing and control complexity increases
Solution Approach 1:
The downhole tool autonomously monitors its own cyclical activity and performs self-adjustment of operating parameters based on accumulated cycling data. The tool independently detects when resonant frequencies are approached and modifies its operation without requiring complex external control systems
Solution Approach 2:
The system samples cyclical activity at a frequency greater than necessary for basic monitoring (excessive action), which provides redundant data that simplifies processing by allowing threshold-based detection rather than complex analysis, and enables the tool to make adjustments based on partial information rather than complete cycle analysis

AI summary
A technique facilitates an improved operation of a tool, such as a downhole tool. The tool is operated in a manner which provides a dynamic or cyclical loading. The dynamic or cyclical loading of the tool is sampled by a suitable sensing system at a frequency greater than the frequency of the dynamic or cyclical loading to collect detailed data on the dynamic or cyclical loading. The data is used to adjust the tool in a manner which improves operation of the tool. One technique for adjusting the tool is changing the dynamic or cyclical loading of the tool by adjusting the frequency of the dynamic or cyclical loading.
