摘要: 选用两种不同种类的降黏剂-水溶性降黏剂和油溶性降黏剂,分别测定其与塔河稠油采出液的油水界面张力、界面剪切黏度、油水乳状液的稳定性以及降黏效果。研究发现,水溶性降黏剂可以显著降低油水界面张力,油溶性降黏剂则主要影响界面剪切黏度。水溶性降黏剂利于形成油水乳状液,油溶性降黏剂可以提高乳状液的稳定性,并达到较好的降黏效果。此外,将两种降黏剂进行复配,在一定条件下复配体系的降黏效果及乳状液稳定性相对单一体系都显著提高。

Abstract: The oil-water interfacial tension, interfacial shearing viscosity, emulsion stability and viscosity reducing effect were investigated between two kinds of viscosity reducers and Tahe heavy oil. The results showed that the interfacial tension was decreased greatly by the water soluble viscosity reducer, while the interfacial shearing viscosity was mainly affected by the oil soluble viscosity reducer. The water soluble viscosity reducer was beneficial for the formation of the oil-water emulsion. The oil soluble viscosity reducer could improve the emulsion stability and had good viscosity reducing effect. When the oil soluble viscosity reducer was compounded with the water soluble one, the viscosity reducing effect and emulsion stability were greatly improved compared with the single reducer.

Key words: Heavy oil, Viscosity reducer, Emulsion, Interfacial tension, Interfacial shearing viscosity
