陇东油田污水腐蚀机理研究

Study on Corrosion Mechanism of Sewage in Longdong Oilfield

针对陇东油田4种作业污水,研究了水质分析、静态腐蚀测试和现场仪器动态检测,同时分析了不同类型作业污水腐蚀的主要机理。结果显示压裂污水对金属的腐蚀最为严重,其次为采油污水,洗井污水和钻井污水的腐蚀性比较接近。

Water quality,static corrosion test and dynamic corrosion test of four kinds of sewage from Longdong oilfield were studied;main mechanisms of different types of sewage were analyzed.The results show that sewage from fracturing process has the most serious corrosivity to metals,second is oil extraction wastewater,corrosivity of well washing wastewater is closer to that of drilling sewage.
