本文针对滨南油田注聚区生产井采出液腐蚀原因,影响因素及其机理进行了探讨,采用失重法实验考察了聚合物浓度对腐蚀速率的影响;对不同阳离子、阴离子对腐蚀速率的影响进行了探讨,考察了pH值,温度特别是微生物对腐蚀速率的影响,用滨南油田注聚区生产井进行了试验评价。实验结果表明,注聚区生产井采出液中含有的残余聚合物对油井管杆的腐蚀有一定的缓解作用;但是,随着时间的增加腐蚀加重。 In this paper, the causes, influential factors and mechanism of production fluid in injection well of Binnan Oilfield are discussed. The effect of polymer concentration on corrosion rate is investigated by weight loss method. The effect of different cation and anion on the corrosion rate The effects of pH value, temperature, especially microorganism on the corrosion rate were investigated. The experimental evaluation was made with the injection wells in Binnan Oilfield. The experimental results show that the residual polymer contained in the production fluid in injection well zone can alleviate the corrosion of oil well pipe rod. However, the corrosion increases with the increase of time.
