Abstract: Hydrochemical mobility is a parameter reflecting the velocity of the transference front sharp of pollutants in watersoil pore medium, which relates to the soil property, water flow state and physicochemical property of pollutants. The dynamic balance of the soil pillar leaching experiment is used in this article to simulate the transference and transformation of the oil pollutants in the aeration zone of Jilin oilfield under the conditions of natural rainfall infiltration. The results show that the hydrochemical transference can be divided into leaching stage, adsorption stage and equilibration stage. The microbe decomposition is very weak. The concentration attenuation curves of leaching liquid in differentthickness soil layers are quite similar. The scale effect has been considered between indoor experiments and natural environment to determine the retardation factor and the hydrochemical mobility properly.

Key words: oil pollutant, soil layer in aeration zone, hydrochemical mobility, scale effect
