Temperature sensing using distributed acoustic sensing |
摘要 |
An embodiment of a method of measuring temperatures includes: taking distributed acoustic sensing (DAS) measurement data by transmitting interrogation signals into an optical fiber disposed in an environment of interest, and receiving reflected signals over a selected time period from the optical fiber; processing the DAS measurement data to separate components of the DAS data associated with changes in temperature; and generating a temperature change profile for the selected time period based on the separated components of the DAS data. |
