摘要: 建立了由细管驱替实验测定驱替气体在油藏流体中的对流扩散系数的测定方法。测定了CO2分别在正辛烷、正十四烷中的对流扩散系数,并研究了驱替速度及正辛烷、正十四烷分子量对扩散的影响。Abstract: The method for measuring convective diffusion coefficients of driving gases in reservoir fluid by slim tube displacement method has been established in this work. The convective diffusion coefficients of CO2-normal octane and normal tetradecane systems have been measured and the effect of driving rate and the molecular weight of normal octane and normal tetradecane on the convective diffusion have been investigated.
