摘要：

研究化学采油聚合物-表面活性剂二元复合驱中的毛管数曲线和相渗曲线。以毛管数与残余油关系实验曲线为基础完善了毛管数曲线数学表达式和以毛管数值为变量复合驱相渗透曲线的数学表达式,并成功用于化学驱油模拟软件中。经算例测试表明,采用新的毛管数曲线表达式和相渗曲线表达式的数值模拟更能反映复合驱采油机理和规律,适应现代采油技术的需求。

Abstract:

This paper studies capillary number and residual oil saturation curve and relative permeability curve of SP flooding. Based on experimental curve, the mathematical description of capillary number and residual saturation curve is proposed. On this new description and in collaboration with mathematical model of software UTCHEM, this paper proposes a new mathematical description of relative permeability curves in addition, which treat capillary value as a variable and applies to a kind of simulation software successfully. Some typical simulation experiments indicate that the numerical simulation which applies new description of capillary number and residual oil saturation curve and relative permeability curve can reflect the mechanism and discipline of SP flooding more accurate.

Key words: petroleum simulation; SP flooding; capillary number curve; relative permeability curve; field simulation experiment; SP flooding software
