Online Corrosion Detection and Safety Assessment of Oil and Gas Mixed Transmission Pipelines
In response to the corrosion problem of the oil and gas mixed transmission medium in a single well pipeline of Tahe oilfield that has been suspended for a long time,through preliminary analysis of corrosion factors and causes,there is a risk of internal corrosion in the pipeline.By adopting online corrosion detection technology,corrosion detection and evaluation of the single well pipeline are carried out.Through on-site testing of five excavation pits in the pipeline,the safety strength of the excavation detection part of the pipeline reaches the level of continued use.However,due to only local pit testing,it cannot be ruled out that there is extremely severe corrosion in other parts of the pipeline.It is recommended to further conduct pressure testing on the pipeline to determine its pressure bearing capacity and identify weak points,providing a basis for the next step of corrosion control.
