摘　　要：纳米颗粒具有尺寸极小、比表面积极大且用量极少等特点,被广泛用于油气藏开发,但有关纳米流体相渗曲线的研究鲜有报道。因此,通过文献调研,综述了毛管数、润湿性、温度及净有效压力等因素对纳米流体驱前后相渗曲线形状的影响,对构建相渗曲线的数学模型方法进行总结和讨论,并结合纳米流体特性优选了适用于纳米流体的相渗曲线获取方法。该研究可为纳米流体相渗曲线的准确获取、相渗数值模型的建立及纳米流体驱油机理的深入研究提供一定的理论参考和指导。Nanoparticles are widely used in oil and gas reservoir development because of their extremely small size,large specific surface area and low dosage,but little research has been reported on the phase permeability curves of nanofluids.Therefore,through literature research,the effects of factors such as the number of capillary,wettability,temperature and net effective pressure on the shape of phase permeability curves before and after the oil displacement by nanofluids are reviewed,the mathematical modeling methods for constructing the phase permeability curves are summarized and discussed,and the method of obtaining phase permeability curves that is applicable to nanofluids is preferred in combination with the characteristics of nanofluids.This study can provide certain theoretical references and guidance for the accurate acquisition of phase permeability curves of nanofluids,the establishment of numerical models of phase permeability and the in-depth study of the mechanism of oil displacement by nanofluids.
