摘　　要：安塞油田油水井套损严重。通过套损井工程测井、水质分析、侧钻拔套管分析、井下挂片试验以及腐蚀监测等手段，明确了安塞油田套管穿孔主要以外腐蚀为主；安塞延安组富含C02、洛河层含02气体是主要腐蚀源，内腐蚀轻微。并提出了相应的防治措施。Casings of producers and injectors are seriously damaged in Ansai oilfield, works through the casing well logging, water quality analysis, lateral pull casing of drilling, downhole etching method and means of corrosion monitoling, clear Ansai outside the main casing corrosion perforation main; Ansai Yanan rich C02, 02 Luo layer containing corrosive gas is the main source of minor internal corrosion. And the corresponding mitigation measures.
