Abstract: This paper analyzed the pollution sources, paths of groundwater environment in Longnan of Daqing during oilfield exploitation.Based on the technological characteristics of oilfield exploitation,a mathematical model on the migration, transformation of oil pollutants was developed,in which,the degradability, the adsorption capacity of oil pollutants were taken into account.An analytical formula of oil pollutant migration in groundwater was derived with continuous sources,and a prediction on the migration was made,which provide an important basis for the environmental impact assessment of oilfield exploitation project.
