In the mathematical model of conventional three-dimensional two-phase non-distributive and distributive tracers problems,the concentration of water component in water phase Cww and the concentration of oil component in oil phase Coo are unknown in the water and the oil component functions,which would cause massive calculations to solve difference equations in the basic model.
常规三维两相非分配示踪剂、分配示踪剂问题的数学模型,其水组分和油组分方程中含有未知量Cww(水组分在水相中的浓度)和Coo(油组分在油相中的浓度),在对基本模型差分求解时会增加很大的计算量。
