| 摘要 |
A smart hydrocarbon fluid production method and system monitor seismic and other acoustic events using a bow spring assembly (40,41) that converts broadside acoustic waves (49) travelling in a non-axial direction relative to a longitudinal axis of an elongate fiber optical sensor (43) into substantially longitudinal vibrations (46A, 46B) and associated microstrain variations in the fiber optical sensor (43) which can be monitored more accurately than broadside vibrations by a Distributed Acoustic Sensing (DAS) interrogation assembly connected to the fiber optical sensor (43). |
