石油磺酸盐/部分水解聚丙烯酰胺体系界面张力的研究

A STUDY OF INTERFACIAL TENSIONS OF SYSTEMS PETROLEUM SULFONATE/PARTIALLY HYDROLYZED POLYACRYLAMIDES

本文主要研究了不同矿化度和正丁醇浓度下,含有或不含有部分水解聚丙烯酰胺(HPAM)时,石油磺酸盐(3A)体系的表面张力及其与模拟油的界面张力。发现加入1000ppm的HPAM对3A体系的表面张力及其与模拟油的界面张力均无明显影响。

The surface tensions and interfacial tensions of systems petroleum sulfonate/partially hydrolyzed polyacrylamide/n-butanol/mineralized water with a model oil have been studied. The sulfonate used is a commercial product, 3A, manufactured by Yumen Refinery. Under experimental conditions of this study (concentrations of petroleum sulfonate 0.005-3％, n-butanol 6％, PHPAM 0 or 1000ppm, salinity 0-1000ppm, 28℃) no interaction (complex formation) of sulfonate with PHPAM is noticed, and the surface and interfacial tensions of these systems with a model oil practically not changed with addition of 1000ppm PHPAM and with change of sulfonate (1—4％) and butanol (6—9％) concentrations. Minerality of the systems is shown to be a favorable factor in creating low interfacial tensions.Increasing total minerality from 1000 to 4000 ppm causes a decrease of interfacial tensions from 10^(-1) to 10^(-3)mN/m.
