| 摘 要： | 通过对近年来轻非水相液体在非饱和带的污染机理、毛细压力-饱和度-相对渗透系数关系以及数学模拟的分析,总结了在三相流模拟过程中主要参数及物理过程的研究方法以及近年来研究非饱和带轻非水相液体污染的各种数学模型,论述了各种方法的优点和不足,提出需进一步研究解决滞后现象对油分布的影响;三相同时流动时气相对其他两相的影响;非等温条件下轻非水相液体进入包气带的污染迁移机理;开展原位实验研究复杂条件下的轻非水相液体污染迁移问题。

| Abstract: | Through analyzing the pollution mechanism,the capillary pressure-saturation,the relative penetration coefficient relationship,the mathematical simulation situation of light non-aqueous phase liquids in unsaturated zone in recent years,this paper summarizes the research methods of main parameters,the physical process and each mathematical model in recent studies on multiphase flow and pollution in the unsaturated zone by light non-aqueous phase liquids,and points out the merit and deficiency of every method.It is thought that further study should be focused on the influence of lag phenomenon to the oil distribution,the influence of gas phase towards oil and water phase,the migration mechanism of light non-aqueous phase liquids under the non-uniform temperature condition,and the migration mechanism of light non-aqueous phase liquids under complex conditions using field test. |
