摘要
针对目前地面系统配注工艺中聚合物母液黏度损失较大,影响开发注聚效果,增加生产成本等问题,研制并试验了可增强径向力从而提高混合均匀度的新型螺旋式静态混合器,可以避免常规混合单元产生的机械剪切力,有效降低黏度损失;应用锥形梭型杆阀芯低剪切母液流量调节器,实现聚合物母液的流量调节,降低了机械剪切力。此外,应用先进的微生物技术,将产抗生素微生物菌群与NRB菌群进行复配,研发聚驱黏损抑制剂,可杀灭或消耗管道内硫化物、硫酸盐还原菌等微生物,降低聚合物母液黏损2%～5%。
In view of polymer solution viscosity loss in the process of current ground injection allocation system,affect the development effect of polymer injection,increase the production costs and other issues,develop and test applied the novel spiral static mixer which can improve the mixing uniformity through enhancing radial force and the multi spindle valve core low shear polymer liquid flow regulator, so can avoid mechanical shear force produced by the conventional mixing unit,and effectively reduce the viscosity loss.Implementation of polymer liquid flow control and reduce the mechanical shearing force. In addition, by the advanced microbial technology, compound with the combination of antibiotic bacteria and NRB bacteria group,develop biological inhibitors for polymer viscosity loss which can kill or consume the pipeline sulfide,sulfate reducing bacteria and other microorganisms,reduce the viscosity loss of polymer liquid for 2%~ 5%.
