摘要
以塘沽地热田为例,建立了地热水位模拟的数值模型,并利用1991年11月至1995年4月的水位动态资料进行了模型的识别与验证。针对31眼地热井布局方案不甚合理的现状,以地热田水位降深最小及地热井开采时干扰最小为目标函数,以地热田最大水位降深满足设计降深及地热井开采量满足实际需水量为约束条件,建立了地热田开采的双目标函数优化管理模型,求解模型得到了优化开采方案。通过与现状开采方案的对比,说明所制定的优化开采方案是合理的。
The numerical model simulating the table of thermal groundwater in Tanggu district, Tianjin City, is developed and the validity of the model is verified by the observation data of dynamic groundwater table in the period from Nov. 1991 to Apr. 1995. The minimum drawdown of water table and the minimum interference of adjacent wells during exploitation are set as the objective functions. The design drawdown and required water discharge are set as the restraint conditions. On this basis the optimized management model with double objective functions is established and the optimal exploitation scheme can be obtained by solving the model. The resonability of this method is verified by exploitation practice.
