demonstrate a non-intrusive dynamic monitoring method of oil well flow based on distributed optical fiber acoustic sensing (DAS) technology and the turbulent vibration. The quantitative measurement of the flow rate is theoretically acquired though the amplitude of the demodulated phase changes from DAS based on the flow impact in the tube on the pipe wall. The experimental results show that the relationships between the flow rate and the demodulated phase changes, in both a whole frequency region and in a sensitive-response frequency region, fit the quadratic equation well, with a max R2 of 0.997, which is consistent with the theoretical simulation results. The detectable flow rate is from 0.73 m3\/h to 2.48 m3\/h. The experiments verify the feasibility of DAS system flow monitoring and provide technical support for the practical application of the downhole flow measurement.<\/jats:p>","DOI":"10.3390\/s22114044","type":"journal-article","created":{"date-parts":[[2022,5,31]],"date-time":"2022-05-31T02:30:06Z","timestamp":1653964206000},"page":"4044","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Non-Intrusive Pipeline Flow Detection Based on Distributed Fiber Turbulent Vibration Sensing"],"prefix":"10.3390","volume":"22","author":[{"given":"Ying","family":"Shang","sequence":"first","affiliation":[{"name":"Laser Institute, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250014, China"}]},{"given":"Chen","family":"Wang","sequence":"additional","affiliation":[{"name":"Laser Institute, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250014, China"}]},{"given":"Yongkang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Laser Institute, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250014, China"},{"name":"Jinan Institute of Quantum Technology, Jinan 250101, China"}]},{"given":"Wenan","family":"Zhao","sequence":"additional","affiliation":[{"name":"Laser Institute, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250014, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7442-9182","authenticated-orcid":false,"given":"Jiasheng","family":"Ni","sequence":"additional","affiliation":[{"name":"Laser Institute, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250014, China"}]},{"given":"Gangding","family":"Peng","sequence":"additional","affiliation":[{"name":"School of Electrical Engineering and Telecommunications, University of New South Wales, Sydney, NSW 2052, Australia"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"209","DOI":"10.1002\/(SICI)1098-2760(19980620)18:3<209::AID-MOP14>3.0.CO;2-Z","article-title":"Fiber-opitc Fabry-Perot flow sensor","volume":"18","author":"Fang","year":"1998","journal-title":"Microw.
