摘要： A method of measuring fluid in-flow in a region of interest in a wellbore comprises deploying a fiber optic cable concurrently with placement of a downhole tubular, transmitting a light signal along the cable and receiving a reflected signal from the region of interest, and interpreting the received signal to obtain information about fluid flowing in the region of interest. The wellbore may include a horizontal portion. The received signal may also be interpreted by assessing amplitude and frequency spectra across array of channels, conditioning the received signal by removing at least a portion of the signal that is not related to flow, assessing flow regimes across depths and times, calculating axial flow/s within the wellbore using relationships for axial flow, and calculating flow into or out of the wellbore at one or more points using relationships for flow through an orifice.
