摘要：
A method and device for monitoring oil field operations with a fiber optic distributed acoustic sensor (DAS) that uses a continuous-wave fiber optic distributed acoustic sensor with a very small spatial sampling while being able to sense acoustic events that have a large bandwidth by employing a demodulation/decoding method utilizing multiple spread-spectrum codes.
