首先对地下水动力场进行了数学描述，以流体势分布度量水动力场，建立了地层埋藏史与流体压力孕育史恢复的数学模型，以此可作为恢复古水动力的重要依据；最后提出了模型实现中的一些建议，系统阐述了古水动力场恢复的原理和方法 First of all, the groundwater hydrodynamic field is described mathematically, and the hydrodynamic field is measured by the fluid potential distribution. A mathematical model of the history of formation burial and the restoration of fluid pressure history is established, which can be used as an important basis for restoring ancient hydrodynamics. Finally, Some suggestions in the realization are given, and the principle and method of restoration of ancient hydrodynamic field are expounded systematically
