| 摘 要： | 本文针对现河采油厂草古一中转站回水管网腐蚀严重状况，结合现场实际生产情况，分别从腐蚀产物、采出液、温度、二氧化碳、溶解氧、微生物、流速等方面进行研究，表明：草古一污水温度较高，pH值较低，污水体系为：CO2／HCO3^-为主构成的腐蚀介质，并通过正交实验研究表明腐蚀的主次要因素为：温度〉二氧化碳〉溶解氧〉矿化度〉pH值。温度是最重要的影响因素，其次为二氧化碳和溶解氧。结合草古一腐蚀情况，对目前防腐控制技术进行调研，提出了下步防腐控制措施。

| Abstract: | In order to solve the severe corrosion on returning water network of Caogu 1 transfer station in Xianhe oil production plant,corrosive products,produced water,temperature,carbon dioxide,dissolved oxygen,microorganism and flow rate were investigated.The results indicated that the Caogu 1 produced water had relatively high temperature and low pH,and CO2/HCO3-was the major corrosive factors.Results of orthogonal experiments showed that the order of factors on corrosion was: temperature>CO2>dissolved oxygen>sal... |
