溶液黏度模型的研究进展

Research progress on solution viscosity model

黏度的研究对于流体流动的数字模拟、油气藏的开发以及CO_2的地质封存等都有着不可替代的意义,其也是评价油气藏的最终开发效果与反映油气藏经济效益的关键因素,当前关于电解质溶液黏度的理论研究主要存在2大类计算模型,即:(1)基于Erying绝对速率理论、Debye Hückel理论、Einstein方程等相关理论而开发的半经验半理论黏度模型;(2)基于如Jones Dole方程等的经验性黏度模型。

The study of viscosity has an irreplaceable significance for the digital simulation of fluid flow,the development of oil and gas reservoirs,and the geological storage of CO2. It is also a key factor in evaluating the final development of oil and gas reservoirs and reflecting the economic benefits of oil and gas reservoirs. There are two main types of computational models for the study of solution viscosity,namely:( 1) semi-empirical and semi-theoretical viscosity models based on Erying absolute rate theory,Debye Hückel theory,Einstein equation and other related theories;( 2) based on Jones An empirical viscosity model such as Dole equation.
