摘要:

本丈用稳定法浏定WINSOR-Ⅲ型徽乳液体系三相渗流时的相时渗透率曲线;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(δc和δwo)、渗流速度对WINSOR-Ⅲ型徽乳液体系三相渗流的影响,对于超低界面张力下的WINSOR-Ⅲ型徽乳液体系,通过分析大量实脸数据,提出了在用稳定法测其相对于渗透率曲线时,根据分流率来计算各相流体饱和度的方法。

Abstract:

Three-phase relative permeability measurements are made experimentally by the steady-state method for WINSOR-III type micellar fluids.Comparisons are made between the two ways("O/M; W" and "O/M+M/Wn)by which the three-phase relative permeability curves are obtained ,The characteristics of the shape of the curves have been recogiused .Preliminary study of the effects of IFT and flow rate on the three-phase flow behavior has been made .It is established that phase saturations can be calculated from fractional flow rate for steadystate flow under ultra low IFT conditions.

Key words: MicelIar fluid, Three-phase flow, Relative permeability, permeability, Laboratory experiment
