子洲—米脂气田气井腐蚀防护技术研究

Zizhou-Mizhi gasfield corrosion protection technology research

通过介绍子洲-米脂气田近年开展挂片试验、不压井腐蚀检测、起出油管腐蚀调研等气井腐蚀防护研究,确定子洲-米脂气田腐蚀轻微,现用缓蚀剂加注制度可以满足气井腐蚀防护需求,并可以进一步优化加注制度。同时,文章对子洲-米脂气田气井缓蚀剂加注制度进行优化,确定更合理的腐蚀防护方法,以满足气井腐蚀防护需求。

This paper introduces the recent development in zizhou-mizhi gas field coupon tests, snubbing corrosion detection, tubing corrosion research and other gas well corrosion protection research, identified in zizhou-mizhi gas field is slight corrosion, inhibitor filling system can meet the demand of gas well corrosion protection, and can be further optimized filling system. At the same time, the article on in zizhou-mizhi gas field gas well corrosion inhibitor injection system optimization, determine more reasonable corrosion protection meth- ods, in order to meet the demand of gas well corrosion protection.
