摘要

The ways in which pollutants enter the ground water were analyzed, based on the known distribution of contaminated groundwater in two aquifers in an oilfield. The study shows that the anomalies of COD_Mn, Cl^-, NO^-3, and TDS resulting from petroleum pollutants may be used as the reference indices of petroleum contamination. The groundwater polluted by infiltration is a relatively minor threat to the oilfield compared to the pollution by penetration through geosutures resulting from geological structural movements, which is the major cause of groundwater pollution.
