Non-metallic pipelines have partially replaced metal pipelines due to their corrosion resistance, anti-scaling, and long service life, effectively alleviating pipeline corrosion problems caused by surface system corrosion in oil fields. However, due to the insulation properties of non-metallic pipelines, the detection technology for existing non-metallic pipelines is not mature, and most of the non-metallic pipelines in oil fields are in an invisible and hard to find state. They are easily damaged during construction, which brings great inconvenience to the operation and management of oil field pipelines. To solve the safety accidents and geological hazards caused by the unclear distribution of underground pipelines, this paper conducts corresponding research on the detection technology of buried non-metallic pipelines, analyzes the adaptability of existing non-metallic pipeline detection methods to non-metallic pipelines in oil fields, and proposes a new non excavation pipeline detection method - handheld buried pipeline detection method, which is applied and tested in the Shaanbei gas field. The test results have demonstrated the reliability of the handheld buried pipeline detection method and provided its applicable range.
