| 摘 要： | 通过实验研究稠油/水乳状液的表观粘度与分散相液滴直径、含水率和温度的关系。分散相液滴直径越大,表观粘度越小;与轻质油/水乳状液不同,稠油/水乳状液在较低的含水率时即表现出很强的剪切稀释性;温度变化对稠油/水乳状液的表观粘度有显著影响而对相对粘度影响很小。在考虑了剪切率的相对粘度预测模型中,Pal(1989)模型的预测结果与实际测量值较为接近。

| Abstract: | The relationships of apparent viscosity of heavy water-in-oil emulsion to the droplet size,the volume fraction of water and temperature were experimentally studied.The experiment shows that the viscosity decreases with the increase of the droplet size;and being different from light water-in-oil emulsion,the heavy water-in-oil emulsion presents a strong shear-thinning behavior even in lower water content;temperature change affects obviously the viscosity of concentrated water-in-oil emulsion,but it has a little impact on the relative viscosity.The predicted model for relative viscosity of Pal(1989) fits the experimental data well by taking into account the shear rate. |
