摘要: 超稠油输送集肤效应电伴热是输油管道加热的主要设备, 在超稠油输送中发挥了极为重要的作用。一旦伴热管和主管焊接部位发生局部腐蚀就会导致穿孔与破裂, 将会直接影响超稠油输送并带来巨大经济损失。辽河油田特石输油管道发生此局部腐蚀现象, 通过对腐蚀环境模拟进行研究, 得出结论是保温层破裂, 导致水分进入, 使得伴热管与主管发生局部腐蚀。

Abstract: Skin Electric Corrent Tracing(SECT) was the main pipeline heating equipment and plays a very important role in the process of super heavy oil transportaton. The perforation and rupture which were caused by the localized corrosion of heating tracer and main pileline welded joints can directly influence the super heavy oil transportation. The phenomenon was occurred in Liaohe oil field Teshi pumping station. The results show that the insulation layer is broken, and the water get into it, thus the local corrosion is formed between the heating tracer and the main pipeline.
