中文说明：考虑毛管压力，相对渗透率，流体粘度，基质孔隙度，渗透率，网格数量，时间步长影响的二维渗吸作用数值模型。同时考虑不同边界对渗吸作用的影响，包括单一边界条件和混合边界条件，涉及边界条件的处理方法。可计算饱和度分布，压力分布，渗吸采收率曲线，残余油饱和度等。
English Description：
A two-dimensional numerical model considering capillary pressure, relative permeability, fluid viscosity, matrix porosity, permeability, number of grids and time step is developed. At the same time, the influence of different boundary conditions, including single boundary condition and mixed boundary condition, is considered. It can calculate saturation distribution, pressure distribution, imbibition recovery curve, residual oil saturation, etc.
