摘　　要：本文主要研究沿程弥散,通过分析实验结果,对文献上广泛应用的计算弥散系数的公式作了全面分析,提出了确定弥散系数更为完善的两种方法;对同类岩心推导了驱替速度u与弥散系数D的关系式。This paper deals mainly with hydrodynamic dispersion. Based on the analysis of the experiment results and the widely used formulas for calculating dispersion coefficients reported in the literatures, two improved methods are presented for determining the coefficients. The relational expression of flow rates and dispersion coefficient has also been developed for similar cores.
