HYZ-12/AP-P4二元体系与原油界面性质研究

Study on the interfacial tension of HYZ-12/AP-P4 and crude oil binary system

对双离子对表面活性剂HYZ-12与水溶性疏水缔合聚合物组成的二元体系与模拟原油界面行为进行了研究。结果表明,油水界面张力随着HYZ-12表面活性剂浓度的升高先急剧下降后趋于平稳;SP二元体系与模拟油的油水界面张力随着HYZ-12浓度的增加而降低;HYZ-12/AP-P4二元体系中对降低界面张力作出主要贡献的是HYZ-12;一定量的无机盐对降低二元体系界面张力有利。该二元体系在提高采收率方面有一定的应用前景。

Study on the interracial tension of HYZ-12/AP-P4 and crude oil binary system. Result shows that oil-water interfacial tension decreased with the increase of HYZ-12 concentration, when the HYZ-12 concentration is closed to cmc, oil-water interfacial tension was very low. With the increase of HYZ-12 concentration,the interracial tension of HYZ-12/AP-P4 and crude oil decreased. HYZ-12 makes a major contribution to reduce interracial tension of HYZ-12/AP-P4 binary system. And a certain amount of inorganic salt is beneficial to reduce the interracial tension of binary system. The binary system has applieation prospect for enhanced oil recovery.
