气体 -油水乳化液的管内流动是原油开采、油气输运以及许多化工领域中经常遇到的工程现象 ,正确认识油水乳化液在气体扰动下的动力特性对圆管内油、气、水多相流的理论建模具有重要的工程应用和学术价值 .本文通过垂直上升管内油气水三相弹状流的实验研究 ,提出了垂直上升弹状流中油水乳化液黏度计算模型 .基于此模型 ,油水乳化液在气体掺入下的流动特性可表现为气体扰动变稠的非牛顿流体特性和气体扰动变稀的非牛顿流体特性 .
Gas-oil-water emulsion in-pipe flow is a common engineering phenomenon in the field of crude oil extraction, oil and gas transport and many chemical fields. Correct understanding of the dynamic characteristics of oil-water emulsion under the disturbance of gas has important influence on the multi-phase flow of oil, gas and water Theoretical modeling has important engineering application and academic value.In this paper, the experimental study on the three-phase slug flow in vertically rising pipe is put forward to calculate the viscosity of oil-water emulsion in vertical rising slug flow model.Based on this model, The fluid properties of the fluid under gas incorporation can be characterized by non-Newtonian fluid properties thickened by gas perturbations and non-Newtonian fluid properties with gas disturbances.
