Distributed Optical Fiber Vibration Monitoring System (gDAS-S300)
The distributed optical fiber vibration monitoring system sends pulse light to the optical fiber installed in the well and detects the Rayleigh backscattering signal at the same time. When
产品特点
Technical superiority and highlights
Heterodyne phase principle based on Rayleigh scattering
Through phase demodulation and Fourier transform, the noise data in time domain is transformed into acoustic field data in frequency domain to realize the real-time dynamic monitoring of sand and liquid penetration of different downhole perforation clusters.
Provides continuous detection and event location with a minimum spatial resolution of 1 meter
Gauge length options available
Detection of acoustic frequencies ranging from 1 Hz to 20,000 Hz
Single-port single-mode fiber configuration, up to 10 km well depth
Can be used in combination with distributed temperature sensing systems and other downhole tools
