Oil and Gas Pipeline Safety Monitoring Application

A new sensing technology that uses light waves as carriers and optical fibers as media to "sense" and "transmit" external measurement signals.

Puniu HiFi-DAS Distributed Optical Fiber Acoustic Sensing System uses one fiber of the ordinary single-mode communication optical cable laid in the same trench with long-distance oil and gas pipelines as the front-end sensor. It can obtain the frequency, amplitude, and phase information of vibration waveforms around any position along the optical cable in real-time. By identifying specific event types (such as pipeline leaks, pig tracking, mechanical excavation, vehicle driving, manual excavation, etc.), it can accurately locate and issue alarms, achieving online real-time monitoring and security warning for the entire pipeline.

Scope of Application

1. Real-time monitoring and early warning system for third-party pipeline damage:
The system uses advanced distributed acoustic sensing and intelligent analysis technologies. It employs a single-mode fiber optic cable core laid alongside the pipeline as the front-end sensor. This allows for real-time acquisition of soil sound, vibration frequency, amplitude, and phase information near the cable. By combining a unique database and deep learning algorithms, the system conducts data analysis and intelligent threat strategy analysis, achieving precise GIS positioning.
Key features include:

2. Online Pipeline Leakage Monitoring: Solving the leakage monitoring issues caused by manufacturing and installation defects or aging and corrosion of pipelines.

3. Ground Surface Load: Monitoring of buildings or vehicle traffic pressure.

4. Pigging Operation Tracking and Monitoring: The DAS system collects vibration and acoustic signal data from the pipeline surface in real-time to obtain the location information of the pig.

5. Online monitoring of geological disasters around pipelines
Geological disasters caused by internal crustal movements, including:
Geological disasters caused by external environmental factors, including:
Geological disasters caused by special soil conditions
