济宁市城区遥感地热异常及其地热田地质特征

Remote-sensing Geothermal Abnormality and Geological Characteristics of Geothermal Fields in Districts of Jining City

摘要:

济宁市城区地处鲁西南潜隆之济宁凹陷，在以往地热地质分区上为成热条件一般区，目前没有地热成井。通过卫星遥感热红外信息分析，发现该区存在若干地热异常。结合常规地质调查、水井钻孔测温、电测深和热水样分析等异常验证，确认济宁市城区南部存在一个深埋型低温层状地热田。地热田面积大于300km2，热水温度可达50℃，热能资源量在3.95×1018J以上，开发利用前景可观。
