Innovation Solution
A drilling dynamics data recorder system is integrated within downhole tools, featuring a sensor package, processor, memory module, and communication port, enabling real-time data collection and logging of parameters like inclination, acceleration, temperature, and torque, and facilitating Condition-Based Maintenance (CBM).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional downhole drilling tools are used with limited sensors and data processing capability, then device complexity is reduced, but measurement precision and reliability of drilling dynamics monitoring deteriorate
Solution Approach 1:
The data recorder is positioned within a slot in the downhole tool, with the sensor package, processor, memory module, and communication port nested together in a compact integrated assembly. This nesting approach enables comprehensive drilling dynamics monitoring with multiple sensors and processing capabilities while maintaining compatibility with existing downhole tool structures.
2Reliability
If comprehensive drilling dynamics data collection is implemented, then reliability of maintenance scheduling is improved, but use of energy increases due to additional sensors and processing
Solution Approach 1:
The processor collects drilling dynamics data from the sensors and stores it in the memory module at periodic intervals rather than continuously processing all data. This periodic data collection and storage approach enables reliable maintenance scheduling based on accumulated drilling dynamics data while significantly reducing the energy consumption of the sensors and processor compared to continuous real-time processing.
