兰考县地热资源地质特征及潜在环境地质问题研究

Study on geological characteristics of geothermal resources and potential environmental geological problems of geothermal resources in Lankao County

本文针对兰考县地热资源的地质特征及潜在环境地质问题展开深入研究。通过该地区地热资源的分布特征调查和分析,并从地热地质构造、热流场分布、地下水循环等方面揭示了地热资源的地质特征。分析了地热开发利用可能引发的环境地质问题,当地热能过度开采将造成地面沉降、地热流体水量和温度衰减等,地热尾水处理不当会产生“盐污染”和“热污染”,造成地质灾害频发和生态环境破坏。因此,针对地质环境问题,如何更安全、更合理地开发利用地热资源,显得尤为重要。

This study focuses on the geological characteristics of geothermal resources in Lankao County and potential environmental geological problems.An in⁃depth investigation and analysis of the distribution characteristics of geothermal resources in this region were conducted,revealing the geological features of geothermal resources such as geothermal geological structure,heat flow field distribution,and groundwater circulation.An analysis of potential environmental geological problems caused by geothermal development and utilization was also carried out.Over⁃exploitation of geothermal energy may lead to ground subsidence,decline in the quantity and temperature of geothermal fluid,improper treatment of geothermal wastewater leading to“salt pollution”and“thermal pollution”,as well as frequent geological disasters and ecological environment destruction.Therefore,addressing geological environmental issues and finding safer and more rational ways to develop and utilize geothermal resources becomes particularly important.
