摘要
通过对某海上油气田伴生气H2S和CO2检测分析,发现该油气田的主要腐蚀因素是CO2,硫化氢只有个别检测位置含量较高,对海底管道进行了重点分析,并使用NORSOKM-506腐蚀模型对CO2腐蚀进行计算,腐蚀速率在中等到严重的范围,而由于生产中使用缓蚀剂,实际的腐蚀速率会有较大程度的下降。
Based on H2S and CO2 test ＆ analysis of some offshore oil ＆ gas field, the CO2 gas is the main cause of corrosion. H2S content of a few test positions is higher. Selective analysis was made for subsea pipelines, and calculation was made by NORSOK M-506 corrosion model of CO2 corrosion, the corrosion rates are middle to high. Actually, the corrosion rate of subsea pipelines will fall much down due to the addition of corrosion inhibitor on stream.
