渗铝和渗锌碳钢在油田采出水中腐蚀规律研究

摘要

以模拟的油田采出水和海水作为腐蚀介质,采用静态挂片腐蚀失重法对20#碳钢、渗铝碳钢和渗锌碳钢进行腐蚀实验,初步研究了Cl-,Ca2+,HCO3-和温度对20 #碳钢、渗铝碳钢和渗锌碳钢的腐蚀规律.腐蚀评价的结果表明,在模拟的油田采出水和海水的腐蚀介质中,渗锌碳钢的耐蚀性能明显好于20#碳钢和渗铝碳钢.%Simulated oilfield wastewater and seawater were used as corrosive mediums, corrosion tests of 20# carbon steel,rnaluminizing carbon steel and sherardized carbon steel were evaluated via static corrosion weight loss method. The impact factorsrncontaining concentration of Cl- ,Ca2+ , HCOr and temperature were investigated. The research results show chat the corrosionrnresistance performance of sherardized carbon steel is superior to 20" carbon steel and aluminizing carbon steel in the corrosionrnmediums.
