摘要： A flow monitoring system includes a pipe for transporting a fluid therethrough. An optical fiber generally spirals about the pipe along a longitudinal portion having a predetermined length to serve as a single transducer for detecting flow information from the longitudinal portion. A linear polarizer/analyzer circuit communicates with the optical fiber. A light source communicates with the linear polarizer/analyzer circuit and generates a light signal along the optical fiber at a frequency greater than a period of a disturbance to flow past the predetermined length of the transducer. A reflector is disposed along the optical fiber for reflecting the light signal along the optical fiber. An optical detector communicates with the linear polarizer/analyzer circuit. The optical detector determines from the light signal dynamic events along the optical fiber indicative of flow disturbances passing by the transducer.

摘要： A sensing cable includes a pair of sensing fibers that are connected to one another by a U-shaped turnaround section. The turnaround section is a section of sensing fiber coated with a jacket that includes metallic components. The turnaround section is bent and, then, annealed according to a method of the present invention. The turnaround section is robust and reduced in size (i.e., radius). The sensing cable also includes an inner sleeve that surrounds the sensing fibers and an elongated outer armor casing (i.e., including an armor tube and a sealing cap) that encases a terminating end thereof. The armor tube and the sealing cap protect the sensing fiber from mechanical and chemical harm, are reduced in size and facilitate insertion of the sensing cable into downhole environments. The sensing cable has improved operating range up to 300° C.

摘要： A method for calculating a temperature along a length of a sensing fiber of a distributed thermal sensing (DTS) system. The sensing fiber, which has two ends, is heat resistant for operation up to 300° C. The DTS system includes a two-channel DTS interrogator that is attached to each of the two ends of the sensing fiber. The DTS interrogator interrogates the sensing fiber from both ends, calculates a temperature difference between co-located positions along the length of the sensing fiber for each end, and determines an error associated with the temperature difference. Based on the determined error, a corrected temperature value along the length of the sensing fiber is calculated and outputted.
