采用十二烷基硫酸钠(s.s.表面活性剂和s.O_(2)纳米颗粒作为发泡体系,在不同原油沥青质含量下进行泡沫稳定性实验,测量CO_(2)泡沫半衰期;采用扫描电子显微图像、紫外分光光度法测试和Zeta.位测量,分析沥青质降低CO_(2)泡沫稳定性的机理。研究表明:当合成油与发泡体系质量比为1∶9时,合成油沥青质质量分数从0增至15%,s.s.定泡沫半衰期从751 s.少至239 s.s.s.s.O_(2)稳定泡沫半衰期从912 s.短至298 s.当合成油与发泡体系质量比为2∶8时,随着沥青质质量分数增大,s.s.定泡沫半衰期从526 s.短至171 s.s.s.s.O_(2)稳定泡沫半衰期从660 s.短至205 s.由于沥青质与s.s.s.O_(2)纳米颗粒在水相中的相互作用,Zeta.位绝对值减小,颗粒表面电荷降低,导致薄液膜两侧界面之间的排斥力减小,从而破坏泡沫稳定性。
