Abstract: In order to enrich the detection means of buried pipelines in oil field, a thickness measurement and evaluation method by using the ultrasonic thickness measurement technology was introduced, the application in Shengli oil field was illustrated. The results showed that this technology had properties of accurate sampling data and reliable evaluation result, and it provided scientific and just detection data and evaluation result to guide operating, maintaining, repairing and replacing of detected pipelines. To the buried pipelines which can not be practiced by internal inspection and unfit for being non-trenched external test, this technology was the unique and reliable thickness measurement technology at present.
