气相缓蚀剂在埋地套管处的应用评价
Application Evaluation of Volatile Corrosion Inhibition in Buried Casings
摘 要
气相缓蚀剂(VCI)在工业领域有广泛的应用, 可以控制套管环形空间内的多相腐蚀。对比多条管道套管处使用和未使用气相缓蚀剂对腐蚀点的个数、位置、深度、方位的影响, 数据表明使用气相缓蚀剂后腐蚀点的个数同比减少64.2%, >20%深度的腐蚀点个数同比减少90%, 腐蚀点方位分布较为均匀;相比腐蚀威胁更容易发生机械损伤。分析认为气相缓蚀剂在缓减套管内管道腐蚀方面有一定作用。

Abstract
Volatile corrosion inhibitor (VCI) are widely used in the industrial field and it can control multiphase corrosion within casing annular space. The anomaly's number, position, depth, orientation to the pipelines at used and unused volatile corrosion inhibitor were evaluated. Contrast with unused VCI, data show that the number of anomalies and depth (>20%) are reduced 64.2% and 90% respectively, and the orientation of anomalies is more uniform, it is easier to mechanical damage than corrosion threat. The results indicate that VCI has some advantages to mitigate pipeline corrosion within the casing and can effectively solve this particular environment corrosion problems.
