苏里格气田X区油管的腐蚀现状及腐蚀原因分析
|
摘要
通过油管壁厚测试、挂片腐蚀试验、腐蚀产物分析等手段分析了苏里格气田X区井筒油管的腐蚀原因。结果表明:目前该区气井井筒只是存在轻微的腐蚀;H_2O-H_2S-CO_2-Cl~-体系引起的电化学腐蚀是腐蚀的主要原因。结合X区腐蚀控制经验,提出了防腐蚀建议。
The corrosion reasons for oil tubes in X block of Sulige Gas Field were analyzed by means of measurement of tubing wall thickness,coupon corrosion test and analysis of corrosion products.The results show that the corrosion of oil tubes in X block was slight at the present,and the primary reason for tube corrosion was electrochemical corrosion caused by H_2 O-H_2 S-CO_2-Cl~-system.Anti-corrosion suggestions were given in combination with the experience of corrosion control in X block.
