新型聚合物表面活性剂的水溶液性质研究

Study of aqueous solution properties of new type polymer surfactant

采用布氏粘度计测定大庆油田用的4种聚表剂的水溶液粘度及粘度稳定性,结构表明,4种聚表剂溶液的粘度随着聚表剂浓度的增加而增大;随着剪切速率的增大先快速降低,随后变化较小,且在模拟污水中,聚表剂溶液的粘度降低较快;聚表剂溶液的粘度随着时间的延长而降低,在模拟污水,聚表剂溶液的粘度相对稳定。

The viscosity and viscosity stability of aqueous solution of new type polymer snrfaetants in Daqing oil field were studied. The results showed that the viscosity of aqueous solution of four polymer surfactants in- creased with the concentration of polymer surfactants. The viscosity increased rapidly, and then was almost un- changed with the increase of shear rate. The viscosity reduced faster with increasing of shear rate in simulated wastewater than that of water. The viscosity of aqueous solution of four polymer surfactants decreased with prolonging of time, and the viscosity was relatively stable in simulated wastewater.
