摘　　要：为合理开发利用地热资源,根据凤南地热异常区地面调查、浅孔测温、物探、钻探、抽水试验、水质分析,以及水位、水温长期观测等工作手段,圈定了凤南地热异常区的范围、热储规模,初步查明了地热异常区地质条件。经分析研究认为,凤南地热异常区属断裂构造控制的中低温水热系统,北西向张性断裂与北东向压性断裂的复合部位是构成地下热水的良好通道和储集区,地热异常明显,地热类型属Ⅱ-2型。In order to reasonably develop and utilize geothermal resources,the scope and thermal storage scale of the Fengnan geothermal anomaly area have been delineated through ground investigation,shallow hole temperature measurement,geophysical exploration,drilling,pumping test,water quality analysis,and long-term observation of water level and water temperature.The geothermal geological conditions of the project area have been preliminarily identified.After analysis and research,it is believed that the Fengnan geothermal anomaly area belongs to a medium to low temperature hydrothermal system controlled by fault structures.The composite part of the northwest trending tensile and northeast trending compressive faults is a good channel and storage area for underground hot water,and the geothermal anomaly is obvious.The geothermal type belongs to type II-2.
