增城区高滩温泉地热资源评价与开发利用

Evaluation and Exploitation of Geothermal Resources of Gaotan Spa in Zengcheng District

在分析增城区高滩温泉地热田的区域地质环境条件和区域地质特征条件的基础上,通过对原有勘查资料的整理和近期的水文地质试验及水文动态观测结果的对比分析,计算得出地热流体热储温度为118℃,循环深度为1 104 m,渗透系数为0.69 m/d,影响半径为197 m,可开采量为2 591 m3/d,年可利用的热能为218 972 160 MJ,规模属于小型,水量、水质都能得到保证.最后,针对地热资源开发利用现状中存在的问题提出了相关建议,对合理利用地热资源具有一定的指导意义.

Based on the analysis of regional geological environmental conditions and regional geological characteristics conditions of the Gaotan spa geothermal field in the Zengcheng district, through comparative analysis and calculation of the original exploration data, recent hydrogeologieal tests and the hydrological dynamic observations, it is concluded that the thermal storage temperature of the geothermal fluid is 118 ℃ , cycle depth is 1 104 m, permeability coefficient is 0.69 m/d, influence radius is 197 m, exploitable ammount is 2 591 m3/d, annual available heat power is 218 972 160 MJ, these belong to a small scale, and water quantity and water quality can be guaranteed. Finally, against existed problem during the geothermal resources development and utilization, some related recommendations are proposed, which are instrunctive and meaningful for rational use of geothermal resources.
