摘要

用乌氏粘度计测定了聚乙烯吡咯烷酮(PVP)/十二烷基苯磺酸钠(SDBS)和聚丙烯酸胺(PAM)/十二烷基苯磺酸钠混合溶液的粘度,发现:恒定PVP浓度时,PVP/SDBS混合溶液的粘度随SDBS浓度的增加在一特定浓度处陡然增大,到另一更高浓度处粘度不再增加;而同样恒定PAM浓度,PAM/SDBS混合溶液的粘度却随SDBS浓度增加没有多大变化。对上述现象进行了初步解释并初步探讨了其油田应用意义。

Abstract

The viscosity of mixed PVP/SDBS solution as well as mixed PAM/SDBS solution was measured. it was found that when the concentration of PVP is constant, the SDBS can increase the viscosity of PVP/SDBS solution, yet, when the concentration of PAM is constant, the SDBS has little influence on the viscosity of PAM/SDBS solution. This paper preliminarily explains the above phenomenon and the significance of its application in the field.
