In-line Inspection of Multi-deformation Multiphase Pipeline in Nanpu 35-2 oilfield
The electronic geometry inspection of the 6-inch multiphase pipeline in Nanpu 35-2 oilfield found four deformation points in the pipeline,and the use of conventional magnetic flux leakage testing equipment had a high risk of sticking.Therefore,it was necessary to transform the testing equipment to improve the passability of the testing equipment,carry out in-line inspection operations on the pipeline,and collect accurate and reliable data to provide support for the next step of pipeline integrity management.
