研究表明，在毛细压力的动态作用下，多相渗流在多孔介质中处于瞬变状态。忽略毛管压力的动态效应可能会导致工程应用中的一些潜在误差。本文综述了毛细管压力动态效应测量的最新进展，重点介绍了实验装置、实验方法和数据解释方法。对多孔介质和流体的测量技术在精度和测量范围上都有了很大的发展。最先进的测量技术可以测量致密岩石和碳酸盐岩中毛管压力的动态效应，即使在超临界流体存在的情况下也可以测量。在测量过程中，必须记录润湿相与非润湿相之间的压差以及现场流体饱和度。此外，还需要防止末端效应和流动前沿压力的快速变化。通过不同注入压力下的电阻率可以测量流体的饱和度，适用于确定毛管动态压力。半渗透元件是测试毛细管动态压力的关键材料。它们的安装位置从多孔介质域的末端到侧面变化。此外，对于渗透率较低的多孔介质，普遍使用的基于质量平衡的方法不适合计算平均流体饱和度，如果使用质心校正相平均法和本征相平均法来计算平均毛管动态压力，则需要进行标定。本文为评价多孔介质中的多相非饱和渗流提供了参考。
Studies have shown that multiphase flows in porous media are in a transient state with the dynamic effect in capillary pressure. The ignorance of the dynamic effect in capillary pressure might lead to some potential errors in engineering application. In this paper, recent advancements in the measurement of dynamic effect in capillary pressure are reviewed, focusing on the experimental setup, experimental method, and data interpretation method. The measuring technologies are developed both in accuracy and measurement range of porous media and fluids. State-of-the-art measurement technology can measure the dynamic effect in capillary pressure in tight rock and carbonate even with the existence of supercritical fluids. During the measurement process, it is essential to record the pressure difference between the wetting and the non-wetting phases and the in-situ fluid saturation. Besides, the end effect and the rapid change in the pressure at the flowing front need to be prevented. The fluid saturation can be measured through electrical resistivity under various injection pressures, which is applicable to determine the dynamic capillary pressure. The semipermeable elements are particularly the key material for testing the dynamic capillary pressure. Their installation site changes from the ends to the sides of the porous media domain. Additionally, the widely used mass balance-based method is not suitable to obtain the average fluid saturation for less permeable porous media, and calibration is required if the centroid-corrected phase average method and the intrinsic phase average method are used to compute the average dynamic capillary pressure. This paper suggests a reference for the evaluation of multiphase and unsaturated flow in porous media.
