| 摘 要： | 本文利用旋转滴技术研究了化学驱油体系中碱、表面活性剂、聚合物和盐对孤立油滴间聚并规律的影响，并利用聚并实验数据对界面粘度进行了推算。发现表面活性剂的存在不利于油滴的聚并，盐和聚合物的存在可提高油滴聚并速率，碱对聚并的影响具有表面活性剂和盐的双重作用。

| Abstract: | This paper studies the effects of alkali,surfactant, polymer and brine in chemical floodingsystem on coalescence behavior of isolated oil droplets by spinning drop technique. The inter-facial viscosity was calculated from experimental data of colaescence. It has been showed thatthe presence of surfactant is unfavorable for oil droplet coalescence ,the presence of brine andploymer can improve coalescence rate of oil droplets ,and the effects of alkali on coalescenceserves a dual purpose with surfactant and brine. |
