| 摘 要： | 采用ＸＲＤ，ＸＰＳ和ＥＰＭＡ对中原油田文２３－１，２３－８气井油管腐蚀产物和管材进行分析，并试验了碳钢在ＣＯ２介质中的腐蚀，研究结果表明，天然气中的ＣＯ２及凝析水是气井腐蚀的主要原因，管材的非金属夹杂物（ＭｎＳ，Ａｌ２Ｏ３）含量超标，是加速油管在ＣＯ２环境中局部腐蚀穿孔破坏的一原因，还探索了应用缓蚀剂防止气井ＣＯ２腐蚀的可能性。 |
| 关 键 词： | 气井 油管腐蚀 失效分析 缓蚀剂 腐蚀 |

| Abstract: | Oil pipes and their corrosion products of WEN23-1 and 23-8 wells in Zhongyuan oil field were studied by using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and electron probe microanal-yser (EPMA). Corrosion tests of carbon steel in solutions containing CO2 were carried out. The results showed that CO2 and condensate water were the primary factors causing corrosion of gas well. Nonmetallic inclusion (MnS, Al2O3) in oil pipe was another cause to accelerate localized corrosion and cracking failure of oil pipes in the medium with CO2. The possibility of application of inhibitor to prevent CO2 corrosion of gas well was discussed. |
