摘要
合肥市滨湖新区位于义城盆地东部。据前人对该区区域地质、水文地质、地热地质等研究及部分钻孔揭露热水情况,认为滨湖新区具备形成低温地热田的地质条件,未来地热开发前景可观。作为重点规划区,滨湖新区的地热资源利用对合肥市乃至安徽省的经济发展都具有重要意义,因而开展合肥市滨湖新区地热资源潜力评价工作尤为迫切。在收集研究前人资料基础上,通过开展地质调查、物探、水质测试、综合研究等多种技术方法,细致查明了区内地热地质条件,进行了地热成矿条件和地温场特征分析。基于以上系统开展了合肥市滨湖新区地热资源潜力预测评价,利用热储法计算得到区内地热能资源总量为3.295 8×10^(14)Kcal,属潜力大的大型地热田。滨湖新区地热资源潜力评价工作成果较为丰硕,明确了肥东凹陷层状低温地热资源分布区(Ⅰ)为下一步地热勘查范围,为后期滨湖新区地热勘查基金项目的申报开展提供了详实有力的立项依据,更为该区有望实现的地热资源开发利用奠定良好基础。
Binhu New Area of Hefei city is located in the eastern part of Yicheng basin.According to previous studies on regional geology,hydro-geology,geothermal geology and some boreholes to expose hot water in this area,it is believed that Binhu New Area has geological conditions to form low-temperature geothermal fields,and the prospect of future geothermal development is promising.As a key planning area,the utilization of geothermal resources in Binhu New Area is of great significance to the economic development of Hefei city and even Anhui province,so it is especially urgent to carry out the evaluation of geothermal resource potential in Binhu New Area of Hefei city.Based on the collection and study of previous data,geothermal geological conditions in the area were meticulously identified and geothermal metallogenic conditions and geothermal field characteristics were analyzed by carrying out geological survey,physical prospecting,water quality testing and comprehensive research and other technical methods.Based on the above system,the prediction and evaluation of geothermal resource potential in Binhu New Area of Hefei city was carried out,and the total amount of geothermal energy resources in the area was calculated to be 3.2958×10^(14)Kcal using the thermal storage method,which is a large geothermal field with great potential.The evaluation of geothermal resource potential in Binhu New Area is fruitful,and the distribution area of stratified low temperature geothermal resources in Feidong depression(Ⅰ)is clearly defined as the next geothermal exploration area,which provides a detailed and powerful basis for the declaration of geothermal exploration fund projects in Binhu New Area at a later stage,and lays a good foundation for the expected development and utilization of geothermal resources in the area.
