摘要
针对大庆石油管理局宋芳屯油田开发建设的实际情况 ,分析了石油污染物在土壤中运移的规律 ,并建立了非饱和带污染物迁移和地下水运动模型 .通过求有限元数值解 ,利用该模型对石油污染物在土壤中的迁移情况进行了模拟预测 ,结果显示了石油污染物可能对土壤造成污染的范围和影响程度 .
On the basis of case studies on the oil field construction, the mechanism of the petroleum pollutant transport in soil was analyzed. A coupled numerical model of pollutant transport and groundwater flow in the unsaturated subsoil is established. This model is applied to simulate the transport of petroleum pollutants in Songfangtun oil field, Daqing Petroleum Administration, which is one of the biggest oil fields in China. In combination with the field survey,the extent of the petroleum pollution to the soil in relation to oil field construction is simulated and the mechanism of pollution and its influence factors are analyzed.
