为解决磨溪气田的腐蚀问题，研制了油溶性成膜缓蚀剂ＣＺ３－１与水溶挥发性缓蚀剂ＣＺ３—３，并将其复配使用．在室内采用常压、８０℃静态试验和高压（高Ｈ２Ｓ气体分压、高ＣＯ２气体分压）、８０℃静态试验评价了ＣＺ３—１和ＣＺ３—３复合使用时于含Ｈ２Ｓ、ＣＯ２、Ｃｌ－及高矿化度等腐蚀介质中的缓蚀作用；在现场试验中采用了加拿大卡普罗克（ＣａＰｒｏｃｏ）腐蚀监测系统考察了ＣＺ３—１和ＣＺ３—３复合使用时对气井地下管串及井口设施的缓蚀效果．室内评价及现场监测均表明ＣＺ３—１和ＣＺ３—３复合使用时在含Ｈ２Ｓ、ＣＯ２、Ｃｌ－及高矿化度等腐蚀介质中有良好的缓蚀效果．
In order to solve the corrosion problem in Moxi gas field, oil-soluble film-forming corrosion inhibitor CZ3-1 and water-soluble volatile corrosion inhibitor CZ3-3 were developed and used in combination. Atmospheric pressure, 80 ℃ static test and high pressure (high H2S gas partial pressure and high CO2 gas partial pressure) were adopted in the laboratory. The static test at 80 ℃ was carried out to evaluate the effect of CZ3-1 and CZ3-3 on the gas- And high salinity and other corrosive media. In the field test, a Canadian Capproco corrosion monitoring system was used to investigate the effect of CZ3-1 and CZ3-3 on the underground pipe string and wellhead facilities The corrosion inhibition. Both indoor evaluation and on-site monitoring showed that CZ3-1 and CZ3-3 had good corrosion inhibition effect in corrosive medium containing H2S, CO2, Cl- and high salinity.
