| 摘 要： | 根据土壤中溶质迁移转化模型，建立土壤中引油类污染物质迁移转化数值模拟模型，以预测在油井井场附近，石油类污染物质在土壤剖面的分布、迁移和转化,在大地龙北油田开发建设工程环境影响评价中，应用此模型预测石油对土壤的污染，为环境影响评价提供依据预测结果与实验结果相近，认为在通常情况卜地表的石油主要积累在30cm以上的土壤中，下渗的最大深度为80cm，不会对地下水造成污染

| Abstract: | Based on the solute transport and transformation model, a numerical simulation model for oil pollutanttransport and transformation is presented, which can predict the distribution, migration and transformation of oilpollutant in the soil. In the case study of the environmental impact assessment of Longbei oil field development,the prediction of soil pollution by oil is conducted through the application of this model, and the results similar tothe data of experiments. It shows that the oil on ground,which accumulates more than 30cm in the soil, can permeate 80cm at most; and will not pollute the groundwater under common conditions. |
