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。
The viscosities of polyvinylpyrrolidone (PVP) / sodium dodecylbenzenesulfonate (SDBS) and polyacrylamide (PAM) / sodium dodecyl benzene sulfonate solution were determined by Ubbelohde viscometer. It was found that constant PVP At the same concentration, the viscosity of PVP / SDBS mixed solution increased sharply at a certain concentration with the increase of SDBS concentration, while the viscosity of PVP / SDBS mixed solution did not increase at another higher concentration. With SDBS concentration did not change much. The above phenomena are preliminarily explained and the significance of the application of the oilfield is discussed.
