裂隙介质中LNAPL污染物迁移研究进展

Research Progress on the Migration of LNAPL Pollutants in Fractured Media

石油化工行业的兴起推动了经济的快速发展,石化产品为社会各行各业的繁荣提供了物质基础,但近年来石油仓储工程在裂隙岩体中的泄漏污染问题频繁出现,地下水污染日益严重,给国家能源安全和城市供水安全带来了严峻考验。以地下水的开发利用与污染修复为背景,简要介绍了裂隙介质中多相流迁移数学模型,重点从机理、模型以及数值模拟研究等方面对LNAPL在裂隙介质中的迁移规律研究进行了详细分析,并对目前监测方法的应用作了介绍,进而对现有研究成果的不足和未来发展进行了展望,以期为LNAPL在裂隙岩体中的迁移预测和修复提供参考。

The rise of the petrochemical industry has promoted the rapid economic development and the petrochemical products have provided a material basis for social prosperity.However,in recent years,the leakage and pollution of oil storage projects in fractured rock masses have frequently appeared and groundwater pollution has become increasingly serious.The national energy security and urban water supply security are severely tested.Based on the development and utilization of groundwater and pollution remediation,the mathematical model of multiphase flow migration in fractured media was briefly introduced.It focused on a detailed analysis of the research on the migration law of LNAPL in fractured media from the aspects of mechanism,model and numerical simulation and the application of current monitoring methods was introduced.Furthermore,the deficiencies of existing research results and future development were prospected in order to provide a certain reference for the migration prediction and repair of LNAPL in fractured rock masses.
