摘要
辽河油田以开采上第三系地下水为主,已出现降落漏斗、水质恶化及咸水入侵等问题。文章应用Visual MODFLOW模型,建立了地下水流数值模拟模型,对不同开采方案下的地下水动态变化进行了预测和分析,确定了最佳开采量和最优开采布局。建议调减开采量和调整地下水开采布局以实现辽河油田地区水资源可持续利用。
With the development of the Liaohe oil field, water supply has increased. Depression cones in groundwater levels have occurred and continued to expand in the upper Tertiary aquifer due to overexploitation, and water deterioration and salt water intrusion have also been encountered. Numerical model of groundwater flow was built up by means of the Visual MODFLOW, and water levels in 2010 and 2020 were forecast on the basis of developing countermeasures. According to present water resource development and national economic water needs, water usages have been forecast and reasonable countermeasures have been designed. Groundwater dynamics have been forecast and analyzed to decide the optimal development and distribution of pumping wells. The optimal results show that water levels rise slowly under decreasing development in the serious overdevelopment district, the area of the depression cone has been expanding. Rearrangement of groundwater development will be the best way to assure sustainable water resources in the area.
