摘要
目前的聚合物驱数值模拟器都不具有聚合物参数估算功能,也没有一套具体的参数估算方法,需要研制具有参数估算功能的数值模拟前处理模块。通过从实验室获取黏浓曲线、流变性关系曲线、渗透率下降系数曲线和吸附曲线,并对描述这些性质的函数关系模型进行了适当的数学变换,利用最小二乘法求解模型,在此基础上,实现了参数估算的界面化。应用此参数估算模块计算数值模拟参数大大提高了聚合物驱数值模拟的工作效率。
At present,the numerical simulator for polymer flooding has no parameter estimation function and there is no specific estimation method as well.Therefore,preprocessing model of numerical simulation is necessarily to be developed. Through laboratory analysis of viscosityconcentration curve,rheology curve,permeability decline coefficient curveand adsorption curve and appropriate mathematical conversion of these function relations,least square method is adopted to solve this model.On the basis of that,the visual interface of parameter estimation has been realized.By using of parameter estimation model,enhance the working efficiency of numerical simulation for polymer flooding.
