摘　　要：2009年,渤海某油田在进行防垢剂中试时,发现防垢剂注入泵密封钢珠和柱塞杆都出现了变黑不能正常工作的问题。通过分析腐蚀失效原因,优化防垢剂配方和更换防垢剂注入泵相关部件,防垢剂注入泵的腐蚀失效问题得到了有效的解决,相关经验值得借鉴。in 2009,the surface of piston and seal steel ball turned black and couldn＇t work well.Based on the failure analysis and optimization of scale inhibitor formulation,the corrosion problem was solved successfully after new piston and seal steel ball were replaced.The experiences can be used as referenced by other offshore oilfield.
