Modflow软件在矿山地质环境保护与恢复治理方案中的应用——以鄂尔多斯盆地某油田为例

Application of Modflow in land vegetation and environment protection in mines: A case study on an oil field in Erdos basin

含水层预测评估及地下水监测点布设是矿山地质环境保护与土地复垦方案中的重要部分,鉴于目前矿山地质环境保护与土地复垦方案中含水层预测评估多采用定性评估,很难有针对性地提出地下水防治与监测措施。文章以甘肃鄂尔多斯盆地某油田为例,利用Modflow软件建立地下水数值模型,通过数值模型的建立与校正,预测油田建设、施工对地下水环境影响,使含水层预测评估从定性评估趋于定量评估。

Aquifer prediction and assessment as well as layout of groundwater monitoring pointsare important parts of land vegetation and environment protection in mines. Because of the fact that so far the aquifer prediction and assessment in land vegetation and environment protection in mines are mostly qualitative assessment,it is difficult to put forward groundwater preventions and monitoring measures. To tackle the issuesa groundwater numerical model of an oil field in Erdos Basin is established by using Modflow as an example.. Through establishment and correction of the numerical model,influence of oilfield construction and operation on groundwater environment are predicted. This method makes prediction and assessment of aquifer tends to improve from qualitative to quantitative assessment.
