摘　　要：为了解天津浅层孔隙含水介质对石油类污染物的吸附特征和油类在地下水中的迁移运动规律,利用宝坻和大港地区两个钻孔岩芯配制7个土样,以柴油类比石油,进行了室内静态吸附实验与动态淋滤实验,结果表明:(1)该地区浅部不同岩性地层对石油类污染物的吸附模式符合线性等温吸附模式,(2)石油类污染物在淡水区含水层中迁移10m需要700 d,在咸水区含水层中迁移10m 需要500 d,个别地点石油的超标不会造成大面积污染。To understand the adsorption property of Tianjin shallow porous aquifer medium to petroleum pollutants, and transportation law of petroleum in salt and fresh water aquifers, seven soil samples were made using 2 bores＇ core in Baodi county and Dagang district. Static adsorption experiments and dynamic filtering pole experiments were conducted with diesel oil liquor simulating contamination, it is concluded：（1） adsorption mode of soil samples to petroleum was linear isothermal adsorption equation,（2） it takes 700 days to transport 10 meters for petroleum in fresh aquifer then 500 days in salt aquifer. Therefore extra heavy concentration of petroleum in individual sites will not induce large area of groundwater pollution.
