摘　　要：通过对气井水分析、气分析和腐蚀速度测试 ,研究了中原油田文 2 3气田气井腐蚀的主要原因。结果表明 ,气井的腐蚀主要是由于CO2 的酸性腐蚀所引起 ,而H2 S和细菌腐蚀并不严重。产量大、压力高的气井腐蚀较严重 。The main causes of corrosion of gas well in Tianwen 23 Gas Field of Zhongyuan Oil Field were studied through the analysis of water and gas from the gas well and testing of the corrosion rate. The results showed that CO 2 acidic corrosion was the culprit of the corrosion of the gas well while H 2S and bacteria played a very miner part in the corrosion. Protection measures should be taken for the high-production and high-pressure gas wells which suffered serious corrosion.
