摘要
对CO2在油田模拟采出水中碳钢的腐蚀情况和影响因素进行了试验分析和讨论。分别对型号为HJF-94和WSL-1的两种油田常用缓蚀剂的性质和缓蚀效果进行了测试。结果表明,HJF-94缓蚀剂,在较低和较高的浓度范围内,有较好的缓蚀效果;WSL-1缓蚀剂,在较低和较高的浓度范围内,有很好的缓蚀效果,尤其在较高浓度时缓蚀效果非常好。
Carbon dioxide is a species of weak acidic gas, it is an corrosive in oil and gas industries. The influencing factors of CO2 corrosion are discussed and analyzed for simulated extraction water of oil-field in which carbon dioxide dissolved. The characters of two common used oilfield corrosion inhibitors, HJF-94 and WSL-1, were tested. The results showed a good effect of inhibition after using the two corrosion inhibitors in the ranges of lower and higher concentrations. In this experiment, the WSL-1 exhibited better effect than the HJF-94 and the best effect appeared in high concentrations.
