The relationship between capillary pressure and water saturation is established based on the assumption that the height of water rise in a single capillary is equivalent to the height of log samples above the bottom of oil-water transition zone.

• 该方法认为、水沿水湿毛细管压力上升高度相当于油水过渡区中测井解释样本点距离过渡区底界面高度，从而把毛细管压力和测井解释样本点含水饱和度联系起来。
