What are requirements for quartz accelerometers in oil and drilling fields?
In the oil and drilling fields, quartz accelerometers are used in various applications such as downhole monitoring, vibration analysis, and seismic exploration. These environments demand robust, high-performance sensors capable of operating under extreme conditions. Here are the key requirements and specifications for quartz accelerometers in the oil and drilling fields:
Key Requirements
1.High Temperature Tolerance
·Temperature Range: Must operate accurately at high temperatures, typically up to 200°C or even higher for some downhole applications.
·Temperature Stability: Minimal drift in performance characteristics with temperature changes.
2.High Pressure Resistance
·Pressure Range: Able to withstand high-pressure environments found in deep wells, often up to 20,000 psi or more.
3.Durability and Ruggedness
·Shock Resistance: Must endure high levels of mechanical shock, often up to 10,000g.
·Vibration Resistance: Capable of withstanding severe vibration and dynamic conditions during drilling operations.
4.Long-Term Stability and Reliability
·Bias Stability: Very low bias drift over time, critical for long-term downhole monitoring.
·MTBF (Mean Time Between Failures): High reliability to minimize downtime and maintenance costs.
5.Sensitivity and Accuracy
·Sensitivity: High sensitivity to detect small vibrations and movements.
·Accuracy: High accuracy and precision to provide reliable data for analysis.
6.Frequency Response
·Bandwidth: Wide frequency response to capture a broad range of vibration frequencies, typically from a few Hz to several kHz.
7.Corrosion Resistance
·Material: Use of corrosion-resistant materials to withstand harsh chemical environments.
8.Compact Size
·Form Factor: Small and compact to fit in tight downhole spaces.
Applications in Oil and Drilling
·Downhole Monitoring: Measuring vibrations and movements to monitor drilling operations and detect abnormalities.
·Seismic Exploration: Used in geophones for seismic surveys to map subsurface structures.
·Drill Bit Dynamics: Monitoring the dynamics of the drill bit to optimize drilling efficiency and reduce wear.
·Structural Health Monitoring: Ensuring the structural integrity of drilling equipment and rigs.
Example Products
Ericco ER-QA-03C1
·Bias: ≤±5 mg
·Scale factor repeatability: ≤15ppm
·Temperature Range: -40℃~+80℃.
·Range: ±60g
·Shock Resistance: 150g.
·Bandwidth: 800~2500 Hz.
Honeywell Model QA750
·Bias: ≤±8 mg
·Temperature Range: -55 to +95 ºC.
·Range: ±30g
·Shock Resistance: 200 g.
·Bandwidth >300 Hz
These specifications ensure that quartz accelerometers can provide accurate, reliable data in the demanding conditions of the oil and drilling fields, contributing to safer and more efficient operations.
