普光气田是国内迄今为止规模最大、含硫及二氧化碳最高的特大型海相气田,普光气田集输系统采用湿气混输工艺,综合利用了“抗硫管材+阴极保护+缓蚀剂”的腐蚀控制技术,该技术对普光气田集输系统腐蚀起到了很好的控制作用。
The Puguang Gas Field is the largest ultra-large marine gas field in China so far with the highest sulfur content and the highest carbon dioxide. The Puguang gas field gathering and transportation system adopts the moisture mixed transportation technology and comprehensively utilizes “sulfur-resistant pipe + cathodic protection + corrosion inhibitor” Of the corrosion control technology, the technology of Puguang gas gathering system corrosion played a very good role in the control.
