摘　　要：通过对胡19区块生产系统腐蚀因素调查,摸清了腐蚀原因是由于胡19区块产出液中Cl-,CO2含量高,同时含有一定量的O2,H2S和SRB,从而形成弱酸性腐蚀水体。经向套管中注入DQF-2高效缓蚀剂(加药浓度200mg/L)后,产出水的铁离子含量与注药前相比,下降了74.2％;根据腐蚀挂片监测的数据。腐蚀速度由2.11mm/a下降到了0.075mm/a,达到了部分指标的要求。The investigation of the corrosion in Hul9 area are production wells revealed that the culprit is the weak acid water body formed from higher Cl-, CO2 and a certain amount of ft , H2S and sulfate reducing bacteria (SRB) in the production liquid. After the high -efficiency corrosion inhibitor DQF- 2 was injected into the conduit at a concentration of 200 mg/L, the iron ion in the production water was decreased by 74.2% as compared with that before the injection. The data from coupon test show that the corrosion rate is reduced to 0.075 mm/yr from 2.11mm/yr, meeting the specifications.
