油田回注水对地面系统腐蚀因素分析及防腐技术

Analysis of corrosion factor about produced- water on the ground system and anticorrosion technology

油田地面系统腐蚀主要有三种腐蚀类型:大气腐蚀、土壤腐蚀和回注水腐蚀。针对回注水对地面系统的腐蚀从溶解氧、CO2、H2S、细菌、溶解盐、p H值、水温、流速和空泡腐蚀进行了腐蚀机理分析。

The major corrosion forms of oil field ground system are atmospheric corrosion,soil corrosion and produced- water corrosion. On the basis of dissolved oxygen,CO2,H2 S,bacteria,dissolved salt,p H,temperature,flow velocity and cavitation corrosion,analysis corrosion mechanism of produced- water on ground system.
