摘要: 以组分模型为基础,结合黑油模型的推导方式,建立了三维三相八组分的弱凝胶调驱的数学模型,模型中综合考虑了重力、毛管力、流体和岩石压缩性等各种影响因素.在模型的求解上采用了改进的IMPES方法即隐式求解压力,高阶显式求取饱和度的方法进行求解,以此提高饱和度求解的精度,并编制了相应的数值模拟软件,对弱凝胶体系的调驱效果进行了模拟研究.

Abstract: A three-dimensional,three-phase,eight-component mathematical model based on the component model and the black oil model is presented. The model considers main factors,such as gravity,capillary force,compressibility of fluid and rock etc.An improved IMPES (implicit pressure, explicit saturation) method is applied in which the phase pressure is calculated implicity and the phase saturation is calculated with high order accuracy.Based on this mathematical model,a numerical simulator is developed for the profile controlling and flooding with weak gel.

Key words: weak gel, profile controlling and flooding, mathematical model, component model, method with high order accuracy
