重庆南温泉背斜地下热水可持续开发研究

重庆南温泉背斜南温泉、小泉及桥口坝地下热水开发点为一个地下热水系统，过去由于缺乏对地下热水的可持续开发研究，各开发点盲目开采，使得有名的天然南温泉、小泉枯竭。目前开发商正在桥口坝开发地下热水，为了避免重蹈覆辙，及合理开发和保护地下热水资源环境可持续发展，必须进行地下热水可持续开发研究。在分析南温泉背斜地下热水系统物理模型的基础之上，建立相应的有限元模型，并采用实测水位与模拟水位对比进行模型校正，当模拟水位与实测水位相近时，所得的模型是符合客观实际的。采用此模型模拟不同可持续开发方案下，桥口坝地下热水的最大开采量，并对不同开发方案进行分析优选，得到最佳的可持续开发方案。

Research on Sustainable Exploration of the Geothermal Water in Nanwenquan Anticline of Chongqing

The geothermal water of Nanwenquan,Xiaoquan and Qiaokouba is a whole geothermal water system in Nanwenquan anticline of Chongqing.In the past,due to lack of study on sustainable exploration of the geothermal water,the source of geothermal water from Nanwenquan and Xiaoquan was drying up.Now,three enterprises are exploiting the geothermal water in Qiaokouba.There must be a sustainable exploration for the geothermal water,in order to utilize and protect the geothermal water resource.The geothermal water in the three exploiter's areas was quantitatively studied on sustainable exploitation by finite element numerical simulation.The geological mode was generalized and the mathematical model was established.Then,the simulative water level obtained was compared with the actual one,and the mathematical model was identified and adjusted.The right mathematical model has been acquired when the simulative water level obtained was approximate to actual water level.The infiltration of geothermal water was simulated under two schemes of exploitation conditions.An optimum scheme has been obtained by analysis.The maximal yield of exploitation was acquired under sustainable exploitation of the geothermal.
