摘　　要：对管道化学清洗工艺和风送挤涂修复材料性能进行了研究 ,探讨了厚浆型涂料用于高压注水管道内防腐蚀涂层的应用效果 ,介绍了小口径管道清洗修复技术在江苏油田的现场应用情况 :修复管道内径小于 92mm ,压力大于 2 5MPa ,一次性通过弯头数达 4 6 /km ,挤涂长度 1.78km。由此探索出一条适应江苏油田小口径管道清洗修复的新路子。The development of techniques for pipeline cleaning and repairing is introduced. The technology of chemical cleaning and the properties of extrusion coating repairing materials were studied. High build paint has been applied to corrosion protection of high pressure water injection pipeline. The application results of the small diameter pipeline cleaning and repairing technique in Jiangsu oilfield are expounded.
