离子种类和质量浓度对不同温度稠油油水界面张力影响的实验研究
摘要
Abstract
The brine water containing Na+ ,Ca2* ,Mg2 + ions of different mass concentrations were prepared for studying the effect of the composition and mass concentration of ions and temperature on the interfacial tension between heavy oil and brine water. The interfacial tension(IFT) was measured by rotating oil droplets method at different temperature. The influence rules of temperature,ion species and ion mass concentration to the IFT were discussed. The experimental results show: The IFT between heavy oil and the brine water containing Na+ or Mg2 + decreases initially and then increases with the increase of the ion mass concentration,there is a minimum IFT value; the IFT between heavy oil and the brine water containing Ca2+ increases initially,then stabilizes,and finally increases again with the increase of the ion mass concentration. The IFT between heavy oil and the brine water containing Na * or Ca2 + decreases obviously with the rise of temperature,while the IFT between heavy oil and the brine water containing Mg2* decreases initially and then stabilizes with the rise of temperature. The IFT between heavy oil and brine water is controlled by both temperature and ion mass concentration. At low ion mass concentration,the IFT is mainly affected by temperature,while at high ion mass concentration,temperature has greater effect on the IFT between heavy oil and the brine water containing Na * and it has less effect on the IFT between heavy oil and the brine water containing Ca2+ , while ion mass concentration has greater effect on the IFT between heavy oil and the brine water containing Mg2 *.关键词
