摘要
根据多频管中电流、超声导波、瞬变电磁、金属磁记忆4种非接触式管道外检测技术的原理、性能特点、试验应用情况,结合大港南部油田管道实际情况,试验了4种检测技术对油田在用集输管道的适用性、准确性和存在不足。通过4种检测技术一定规模的试验应用,掌握了各种检测评价技术的功能特点及适应性,为进一步开展管道内外检测、缺陷评估、寿命预测等完整性管理积累了经验;另外,通过检测评价修复等工作,降低了管道运行风险、提升了管道本质安全、延长了管道寿命、降低了管道失效率、节省大量管道更换资金,并且对部分技术提出了改进建议。
Based on the theory, characteristics, test application of four kinds of non-contact pipeline inspection technology which are multiple frequency current, ultrasonic guided waves, transient electromagnetic and metal magnetic memory. The technologies are tested for applicability, accuracy and shortcomings combined with real situation of Dagang South Oilfield. Through experiment application of four kinds of inspection technology, the function characteristics of the inspection and evaluation technology are mastered, and the experience of integrity management of pipeline detection, defect assessment and life prediction are accumulated. In addition, through the inspection, evaluation and repair work, the pipeline risk is reduced, the pipeline intrinsically safe is improved, the life of the pipeline is extended, the pipeline failure rate is reduced, money is saved, and some technical Suggestions for improvement are put forward.
