摘要
油田开发对地下水的污染,主要是由于原油在土壤中的转移、油区污染情况以及原油泄漏地质状况等因素导致的。针对大庆油田钻井期可能对地下水环境造成的影响进行了分析,并对事故情况下对地下水的影响范围进行了预测。预测结果表明:油田钻井期正常情况下不会对地下水环境造成影响,如发生井漏事故,主要对承压水层产生影响,根据预测,泄漏后1000天,污染物的影响距离为130 m。该预测结果对于大庆油田钻井过程中制定保护地下水资源的政策具有一定的参考价值。
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.
