CARP内喷涂油管失效分析

Failure Analysis of CARP Inner Spray Oil Tubes

CARP内喷涂油管是一种新型的防腐耐磨油管,在使用过程中,有的出现了油管工厂端接箍和螺纹腐蚀现象,对腐蚀情况进行了详细描述,并且进行了油管的机械性能试验、静水压试验和化学成分分析,对油井采出液进行了组分分析,将该种内喷涂油管进行生产工艺还原后进行了对比试验。在对试验数据分析的基础上,分析了该种油管工厂端螺纹腐蚀的原因,并提出了改进的建议。

CARP inner spray oil tube is a new kind of anti-corrosion and wearable tubes.In the process of using them,corrosion phenomenon occurs to the coupling and screw at the factory end of oil tubes.Based on the detailed description for the corrosion situation,the following things like the mechanical property test,the static water pressure test and chemical components analysis are carried out,together with the group analysis of production fluid of oil wells.Meanwhile,after the reduction of production techniques,the contrastive test is made for this kind of inner spray oil tubes.Based on the analysis of test data,the analysis focuses on the causes of screw corrosion at the factory end of oil tubes,followed by the suggestion of improvement.
