油田埋地管道检测技术应用研究

Research of the Inspection Technology for Oilfield Buried Piping

通过总结目前国内外常用的埋地管道检测方法的原理及其优缺点,并进行现场对比试验,提出了埋地管道检测技术组合方法。通过此组合方法对某油田一段埋地管道进行了防腐层、管体腐蚀全面检测评价。检测结果表明,该综合检测技术可实现对环境敏感区埋地管道的不开挖全面检测,对管道走向及防腐层破损定位精确,满足油田工程应用。

The principles of the buried piping inspectionand exam ination methods normally used in home and abroad,and the advantages and the disadvantages of these methods,were summed through the comparison and testing research,the combined technical methods of inspection for buried piping were propose.This combined technical methods is applied to a buried pipeline of the Oilfield,This buried pipelines are fully tested and evaluated the coating and tube body corrosion.Test results show that,This combined technical methods can detect buried pipelines in environmentally sensitive areas not digging.It can pinpoint the direction and pipeline coating damage points,and can meet the oilfield engineering applications.
