THE PRESSURE-PLATE AND THE GRAVITY DRAINAGE COLUMN EXPERIMENTS WERE TESTED TO CONFIRM THE EFFICIENCY OF THE EMPIRICAL EQUATIONS EXPLAINING THE WATER-NAPL-AIR THREE-PHASE CAPILLARY PRESSURE-SATURATION RELATIONSHIPS. THE PRESSURE-PLATE EXPERIMENTS SHOWED THAT WATER SATURATION IS IDENTICAL TO THE WATER RETENTION CHARACTERISTICS OF AIR-WATER TWO-PHASE CONDITION. ON THE OTHER HANDS, THE GRAVITY DRAINAGE COLUMN EXPERIMENTS SHOWED THAT TOTAL LIQUID SATURATION UNDER THREE-PHASE CONDITION WAS NOT AGREEMENT WITH THE OIL RETENTION CHARACTERISTICS OF AIR-OIL TWO-PHASE CONDITION, WHEN OIL THICKNESS WAS THIN. ON THE OTHER HANDS, ANEW DEVICE WHICH CAN DETERMINE THE UNSATURATED WATER. OIL AND AIR CONDUCTIVITY DIRECTRY WILL BE DEVELOPED IN THE NEAR FUTURE USING DISPERSION COLUMN DEVICES.

本文通过实验验证了水-油-气三相毛细渗透率-饱和度关系经验方程的有效性。平板实验表明，含水饱和度与气水两相条件下的持水特性是一致的。重力泄油柱实验表明，当油膜厚度较薄时，三相条件下的总液体饱和度与油气两相条件下的持油特性不一致。另一方面，一个新的装置，可以确定不饱和水。在不久的将来，将使用分散柱装置来测量油和空气的电导率。
