摘要
本文用稳定法测定了WINSOR-Ⅲ型微乳液体系三相渗流时的相对渗透率曲线;分析对比了由“O/M/W”途径和“O/M & M/W”途径测得的各相流体相对渗透率曲线;对微乳液体系三相渗流相对渗透率曲线特征有了明确认识;初步研究了界面张力(σ_c和σ_(wo))、渗流速度对WINSOR-Ⅲ型微乳液体系三相渗流的影响。对于超低界面张力下的WINSOR-Ⅲ型微乳液体系,通过分析大量实验数据,提出了在用稳定法测其相对渗透率曲线时,根据分流率来计算各相流体饱和度的方法。
The way, adopted by the VIPUT/CHEM simulator, that deals with relative permeabilities of three-phase flow of micellar fluids has been discussed and analyzed. Mathematical statistics applied, emperical equations have been formulated for the threephase relative permeability curves that are suitable for microemulsion flooding in 'L' formation in Yumen oilfield.
