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。
Aiming at the five well areas in Baolang oilfield, the natural corrosivity of carbon steel in soil was compared with that of in situ corrosion test and electrochemical polarization test Weak range. At the same time, the corrosion of sulfate-reducing bacteria in soil was also analyzed. The corrosiveness of soil in Baolong oilfield was comprehensively evaluated in combination with German GW9 multiple indicators method.
