Analysis of the Characteristics and Causes of Geothermal Water in Tiantangshao,Yinjiang,Guizhou
摘要
Abstract
Based on a systematic analysis of geothermal geological conditions,characteristics of hydrochemical field and temperature field in the Tiantangshao area of Yinjiang County,Guizhou Province,the authors summarized the cause of geothermal water in the area,and provided a theoretical basis for the later geothermal water exploration and development planning.The geothermal well of Tiantangshao is located in the Tiantangshao-daobaxiang composite thermal reservoir unit,its geothermal water mainly occurs in the water-bearing layers of limestone and dolomite occuring between Qingxudong formation and Honghuayuan formation,it is rich in Ca2+、SO42-、Mg2+、HCO3-、K+、Sr2+、F-and other anions and cations,and the content of metasilicate is high.The temperature of geothermal water thermal reservior may be higher than 75.5℃,and the water circulation depth is about 1850m.There is no special heat source such as young magmatic rock mass and radioactivity in the shallow part of the area,the secondary fold mountain cap(Tiantangshao)anticline is the main thermal reservoid structure,which stores the heat,under the combined action of the Yangjiaba fault and the overlying insulating water layer of clastic rock,forming the deep reservoir geothermal water with development value in the limestone and dolomite occuring between the upper Cambrian and the lower Ordovician.关键词
