摘要：The concentration and molecular weight of HPAM (HPAM) solutions, temperature, and pH were investigated in order to investigate the effects of HPAM on the amount of silicate scaling in the gathering line with the widely reuse of the Al- kali/surfactant/polymer (ASP) flooding. Heteropoly yellow method for spectrophotometer determination of silicon is applied to quantitative analysis of silicon in ASP-flooded produced water to obtain the acknowledgement that the HPAM have the maximum effect on silicate scale quantity under any conditions. The research provides a reliable basis for the mechanism research of the scaling problem in the oil extraction process of asp flooding and the adoption of scale inhibition and scale inhibitor.
