摘要
VisualMODFLOW是综合MODFLOW、MODPATH、MT3D、RT3D和WinPEST等地下水模型而开发的可视化地下水模拟软件 ,具有水的质点向前、向后示踪流线模拟、任意区域的水均衡、简化数值模拟数据前处理和后处理 ,将模拟的复杂性降到最小等特点。龙西地区是大庆油田新增水源地 ,使用VisualMODFLOW在该地区进行了地下水资源的模拟与预报 ,建立准三维模型 ,发现PCG2求解方法精确度最高。另外 ,把随机模型和MODFLOW模型相结合 ,解决了边界水位在计算中不断变化的问题。按照设计开采量对地下水水位进行预报 ,根据模型预报结果 ,水源地设计开采量是可行的。VisualMODFLOW成功地运用于大庆龙西地区地下水资源的评价 ,操作简便 ,预报准确、可靠 ,说明具有很好的应用和推广前景。
Visual MODFLOW is a visual software on groundwater simulation, consisting of MODFLOW, MODPATH, MT3D, RT3D and WinPEST, ect. It's function is characterized by simulation complexities in trail simulation as running of forward and back of water particles, water balance in different zones, and pre-- and post--processes of data in simplization numerical simulation and so on. The groundwater in Longxi area has been considered as a new water resources of Daqing Oilfield. This software was employed in the groundwater resource assessment of Longxi area of Daqing City. The simulation and prediction of groundwater in this district has been conducted. A quasi--3D model was established, and the precision of solve PCG2 is the best in the simulation. In additional, the problem on the momentarily changing of water table was solved by MODFLOW model combined with random model. This application appears to be successful, precise and creditable to make assessment of groundwater resources.
