| 摘 要： | 本文叙述了一种测定储集岩毛细管压力的新方法。选用某些无机盐的饱和溶液来控制平衡压力,在真空装置上,通过等温吸附实验,测定了两种天然岩心试样在低饱和度下的毛细管压力,结果与脱附法一致。在双对数坐标图上,毛细管压力与含水饱和度呈线性关系,但平衡时间大大缩短。

| Abstract: | A new method of measuring capillary pressure of porous medium is described. Saturated solutions of some inorganic salts are used to control equilibration pressure. The capillary pressures of two natural core samples are measured at low water saturation through vapor phase adsorption experments in vacuum apparatus, The results agree with those of the desorption experiments. The capillary pressure versus saturation relationship appears to be linear on the dual logarithmic coordinate diagram. However, the equilibration time has been decreased greatly. |
