| 摘 要： | 采用静态腐蚀挂片失重方法，研究了胜利油田采出水中主要腐蚀离子成份（Cl^-，Ca^2＋，HCO3^-）对20^#碳钢和渗锌碳钢的腐蚀行为，并对腐蚀原因做出了分析。研究表明，200碳钢及渗锌碳钢的腐蚀速率随腐蚀介质中Cl^-质量浓度的增加而呈现上升趋势；Ca^2＋离子的加入在一定程度促进了20^#碳钢和渗锌钢的腐蚀；HCO3^-对20^#碳钢腐蚀具有先抑制后促进作用。在模拟的采出水腐蚀介质中，渗锌碳钢的耐蚀性能要明显好于20^#碳钢，平均腐蚀速率小于石油行业腐蚀速率（0．076mm／a）控制标准规定。 |

| Abstract: | Adopting static corrosion weight-loss method,the corrosible effect Shengli oilfield produced water containing main ion ingredients(Cl-,Ca2+,HCO-3) on the carbon steel and penetrating zinc steel metal materials was studied,and causes of corrosion were also made analysis.The results show that with the concentration of Cl-increasing,the corrosion rate of 20# carbon steel and the penetrating zinc carbon steel is increased.When the content of Ca2+ ions was added,the corrosion rate of 20# carbon steel and the permeability zinc carbon steel also has a increasing trend.HCO-3 inhibited corrosion rate of 20#carbon steel and then increased;the corrosion resistance of penetrating zinc steel is superior to 20#carbon steel in the simulative oilfield water,the corrosion rate is less than the petroleum industry standard 0.076 mm/a,so penetrating zinc steel metal materials can be used in pipeline of the oilfield. |
