METHOD AND SYSTEM FOR MONITORING FLUID FLOW IN A CONDUIT |
| 摘要 |
A method for monitoring fluid flow in a conduit comprises:
acoustically coupling an optical fiber to the conduit adjacent one or more flow restrictions (R1-R4) in the conduit;inducing a Distributed Acoustic Sensing (DAS) assembly to measure an acoustic noise signature (SNR1-4) generated in the fiber by the fluid flowing through each flow restriction (R1-R4);deriving the fluid flow rate of the fluid (QI, QI+II) flowing through each flow restriction (R1-R4) from the measured acoustic noise signature (SNR1-4); anddisplaying the derived fluid flow rate (QI, QI+II) at a fluid flow rate monitoring display. |

1. A method for monitoring fluid flow in a conduit, the method comprising:
acoustically coupling an optical fiber to the conduit adjacent to a flow restriction in the conduit; inducing a Distributed Acoustic Sensing (DAS) assembly to measure an acoustic noise signature generated in the optical fiber by the fluid flowing through the flow restriction; deriving the fluid flow rate of the fluid flowing through the flow restriction from the measured acoustic noise signature; and displaying the derived fluid flow rate at a fluid flow rate monitoring display. |
