济宁市城区遥感地热异常及其地热田地质特征

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300km^2，热水温度可达50℃，热能资源量在3.95×10^18J以上，开发利用前景可观。

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

Jining districts locate in Jining depression in hidden uplift in southeast of Shandong province. There is no geothermal wells in this area. Through analysis on satellite remote-sensing infrared information, geothermal abnormality has been found in this area. Combining with general geological survey, drilling wells temperature, electric sounding and analysis of thermal water sample, it is regarded that a low temperature cellar type geothermal field occurred in south part of Jining districts with the square of 300km^2. The temperature of hot water can reach 50℃, and the water amount is over 3.95×10^18J with bright future in geothermal resource exploitation.
