缓蚀剂CT2-19在高酸性气田地面管线上的应用

Application of Corrosion Inhibitor CT2-19 at High Sour Gas Field Pipeline

采用专利产品缓蚀剂CT2-19、CT2-19B,在西南油气田公司重庆气矿峰15井及峰15井到高峰站的地面管线上进行了多项酸性气田地面管线不停产状态下的缓蚀剂现场应用试验。结果表明,专利产品缓蚀剂CT2-19、CT2-19B能够较好地适应峰15井的工况,既可单独加注,也可与水合物抑制剂联作,能满足酸性气田冬季开发生产过程中防腐和防冰堵的要求。

The corrosion inhibitor CT2-19,CT2-19B were used at Feng-15 well and the pipeline between Feng-15 and Gaofeng station. The results show the inhibitors can control the corrosion of Feng-15 well and the pipeline,the corrosion inhibitors can use separately or with hydrate inhibitor,this means they can used for all season.
