使石油磺酸盐表面活性剂达到超低界面张力影响因素分析

Influence Factors of Petroleum Sulfonate Surfactants to Achieve Ultra-low Interfacial Tension

界面张力对三次采油中的表面活性剂驱具有重要意义,降低表面活性剂的界面张力,使表面活性剂发挥其最大的作用是在三次采油中关注的问题,在石油磺酸盐表面活性剂溶液中加入不同种类和不同浓度的矿物离子,并测量其界面张力,分析了矿物离子种类和浓度对石油磺酸盐表面活性剂界面张力的影响.

The interfacial tension plays an important significance in surfactant flooding of tertiary oil recovery, so how to reduce the interracial tension of surface active agents and exert the positive influences of surface active agents becomes more and more important in tertiary oil process. In this paper, the interfacial tension of petroleum sulfonate is measured which different kinds and concentrations of the ion is mixed. The effects of the type and concentration of mineral ions on the interracial tension of petroleum sulfonate surfactants were investigated.
