        Abstract:Pollution of groundwater from oilfield development is mainly due to factors such as the transfer of crude oil in the soil,the pollution in the oil zone and the geological conditions of crude oil leakage.In this paper,the influence on groundwater environment caused by the drilling period of Daqing Oilfield is analyzed,and the influence range of groundwater under accident situation is predicted.The prediction results show that the groundwater environment will not be affected by the common drilling period in the oilfield.For the event of a well leakage,the confined aquifer is mainly affected.According to the prediction,1000 days after the leak,the influence distance of the pollutant is 130 meters.The prediction results have certain reference value for the formulation of policies for protecting groundwater resources during drilling in Daqing Oilfield.
