乳液驱油机理的研究是提高原油采收率技术中十分重要的基础研究内容之一。通过试验，用非稳定法较全面地研究了微乳液体系的两相及三相相对渗透率曲线，数据处理采用新的Ｗｅｌｇｅ／ＪＢＮ法。实验结果表明所采用的实验设计与处理方法是适宜的，它与稳定法的实验结果有较好的相容性，通过分析和讨论低界面张力下微乳液相对渗透率曲线的特征、润湿滞后效应及界面张力和流体粘度对相对渗透率的影响，获得了大量有益的结论。进一步完善了对微乳液体系相对渗透率曲线及微乳液在油藏岩石中渗流机理的认识
The study of emulsion displacement mechanism is one of the most important basic research contents in the field of oil recovery technology. Through experiments, the two-phase and three-phase relative permeability curves of microemulsion system were comprehensively studied by non-steady method, and the new Welge / JBN method was used for data processing. The experimental results show that the experimental design and processing method are suitable, which has good compatibility with the experimental results of the stability method. By analyzing and discussing the characteristics of the relative permeability curves of the microemulsion with low interfacial tension, the wetting lag Effects and interfacial tension and fluid viscosity on the relative permeability, obtained a lot of useful conclusions. Further perfecting the relative permeability curve of microemulsion system and the micro-emulsion understanding of seepage mechanism in reservoir rocks
