宝浪油田区域土壤腐蚀性评价

The investigation and Evaluation on the Soil Corrosivity of Baolang Oilfield

针对宝浪油田区域具有代表性的5个井区,通过碳钢在土壤中的室内自然腐蚀埋片试验和现场埋片试验以及电化学极化测量,得出各井区土壤腐蚀性的相对强弱范围。同时还分析了土壤中硫酸盐还原菌的腐蚀情况,并结合德国的GW9多项指标法对宝浪油田区域土壤的腐蚀性进行了综合评价。

The tests on the room coupon,field coupon,and electrochemical polarization have been made, and the results of soil corrosivity have been obtained from the typical five fields in Baolang oilfield. The paper analyzes the corrosion of SRB,and comprehensively evalutes the soil corrosivity of Baolang oilfield according to the multi-index method of Germany GW9.
