摘要：

石油污染多孔介质中含有石油和水分，采用传统的烘干法测定其含水量时，水分和油分会同时产生挥发，无法准确测定含水量。在传统烘干法测定含水量的基础上，根据水分和油分不同的挥发特征，提出了石油污染多孔介质含水量的定义和计算公式，测定了不同石油在多孔介质中的烘干损失系数，建立一种测定石油污染多孔介质含水量的改进烘干法。结果表明：该法测定的石油污染多孔介质的含水量与实际值的误差约为0.10%~0.50%，低于传统方法的测定结果，可用于室内各项石油污染多孔介质的模拟研究。

关键词: 石油污染多孔介质, 含水量, 测定技术, 烘干法

Abstract:

It’s difficult to measure water content of oil-contaminated porous medium accurately by conventional oven drying method, because there are two kinds of liquids (water and oil) in the porous medium, which will volatilize simutaneously when drying. On the basis of conventional oven drying method, we proposed a definition and formula in testing water content of the oil-contaminated porous medium. The oil loss ratio in porous medium was measured according to volatilization characteristics of water and oil. Finally, an improved oven drying method was developed to measure water content in the oil-contaminated porous medium. The results show that testing error of this measuring technique is at order of about 0.10~0.50%, which is lower than that of the conventional oven drying method. This improved oven drying method can be used for lab studies of oil-contaminated porous medium.

Key words: oil-contaminated porous medium, water content, measuring technique, drying method
