| 摘 要： | 本文采用氯化钠作示踪剂测定含水层的弥散系数，并根据实测的溶解油吸附等温线来确定含水介质对石油污染物运移的阻滞系数，从而把反应性石油污染物在地下水中运移化为示踪剂的对流－弥散迁移和溶解油在水相与固相之间转移的叠加，最后作者把所得的耦合模型应用于评价大庆油田排污干渠对地下水污染问题。

| Abstract: | The coefficient of dispersion of aquifer is determined by using NaCl as tracer and the retard factor of water bearing medium to oil contaminant transportation is then determined by the measured adsorption isotherm. The travel of reactive oil contaminant in groundwater is converted into the superposition of convection dispersion of the tracer and the conversion of dissolved oil between water phase and solid phase. Finally, groundwater pollution by sewage from Daqing oilfield is evaluated with the established coupling model. |
