AI Technical Summary
Technical Problem
Existing piezoelectric seismic tow cables are difficult to install, inefficient, and costly in data measurement tasks.
Method used
A multi-data measurement method based on fiber optic tow cables is adopted. Optical wave signals are received through distributed fiber optic detectors, and optical signal processing techniques such as OTDR and OFDR are used, combined with the principles of Raman scattering, Brillouin scattering and Rayleigh scattering, to process the optical wave signals to determine data such as temperature, seismic signals, detector point location and water depth.
Benefits of technology
It reduced the difficulty of seismic cable towing construction, improved construction efficiency, and saved data measurement costs.
