The Application of Internal Corrosion Detection Technology in Long Distance Pipeline

The working principle, site application, application procedure, application methodology and economic evaluation of the internal corrosion detection technology (only MFL as an example) used in Kelamayi Oilfield are introduced. At present, the pipelines with different diameters in Kelamayi Oilfield are more than 2000 km in total lengthen which approximately 951. 2-km-pipeline uses MFL to detect corrosion. Based on the statistics, 21. 3 million RMB yuan is saved by means of this technology. In the article, the application cases of the technology in several pipelines are provided.
