Abstract: An experimental method for measuring steady-state three-phase relative permeability of oil, gas and water in acore samples has been developed in this paper. Oil,gas and water saturation measurement by microwave-weight techniques,relative permeability measurement apparatus and experimental procedures are involued in the method. Three-phase relative permeability of oil,gas and water for a number of water wet sandstone. core samples has been measured by this method in steady state condition. Results indicates that this method is valid to measure three-phase relative permeability of oil, gas and water.

摘要： 本文提出一种测定油藏样品油、气、水三相相对渗透率实验方法,阐述了利用微波一称重技术测定油、气、水三相饱和度、相对渗透率的测定装置及实验程序。在稳态条件下,利用该方法测定了水湿样品的油、气、水三相相对渗透率。实验结果表明,用该方法测定油、气、水三相相对渗透率是可行的。
