Abstract

Pipeline internal inspection gauge (PIG) can find out the internal defects of the pipeline and is one of the most effective pipeline inspection methods. However, the detection of small-diameter pipelines is currently a difficult problem facing by the oilfield integrity management, since the there is no suitable PIG for small-diameter pipeline. In response to this problem this study proposes a detection method for Φ168 small-diameter pipelines based on ultra-high-definition magnetic flux leakage technology. Based on the principle of magnetic flux leakage detection, a magnetic circuit model of ultra-high-definition magnetic flux leakage detection for Φ168 small-diameter pipelines is established, and a PIG for Φ168 small diameter pipelines is designed. It is verified that the PIG designed has good passability through the indoor pulling test. In addition, it has been applied in a pipeline in an oil field with good effect.
