福建省永春洑江地热单元形成机理及资源利用前景分析

Mechanism analysis and resource utilization prospect of Fujian province Yongchun Fu Jiang geothermal formation unit

基于野外调查工作的基础上,文章通过对永春洑江地热单元地热地质条件的分析,认为地热水主要受北东向和北西向断裂构造控制,在断裂带复合处的楔形区内出露温泉,形成火山热-对流热混合型热水系统,其复合部位的楔形区是今后找水的主要靶区;该单元地热水资源较丰富,热水井口温度54.5℃~63.0℃,日可开采热量qc为1.866×108KJ/d,日可开采水量QW为1 087 m^3/d。地热资源丰富,开发利用前景看好。

Based on the basis of field survey of the Yongchun Fu Jiang geothermal unit geothermal geological condition analysis,that hot water is mainly controlled by NE and NW trending faults control. In the fracture belt compound wedge outcropping in hot springs,Formation volcanic heat- on hot water system of heat of mixing flow,the composite part of the wedge is future exploration for the main target zone; element of the geothermal water resources are rich,hot water wellhead temperature 54. 5 to 63. 0 DEG C,recoverable heat QC for 186. 6 × 10^8 KJ / d,day can mining water QW for 1 087 m^3/ D. Rich geothermal resources,development and utilization prospect.
