摘要
为提高地热水生产规模,满足高沙片区地热水的长期供应,特组织高沙片区地热资源储量核实工作。对高沙片区开展1∶2.5万地热地质调查、音频大地电磁测深、高密度电阻率测量、地热地质钻探、钻孔测温、降压试验、岩矿鉴定、水质分析等工作,基本查明了高沙片区地热田地热地质条件,圈定了高沙片区地热田热异常面积为1.33 km^(2);明确了地热流体赋存条件与岩性的关系,热储主要埋藏深度为40.00~121.00 m;确定了地热流体的通道为近南北向断裂及裂隙溶洞发育带。研究为高沙片区地热田地热资源储量计算、勘探开发及远景规划等工作提供重要依据。
In order to increase the scale of geothermal water production,to meet the long-term supply of high sand area of geothermal water,the organization of high sand area of geothermal resources reserves verification work.Geothermal geological survey,audio magnetotelluric sounding,high density resistivity measurement,geothermal geological drilling,borehole temperature measurement,depressurization test,rock and mineral identification,water quality analysis and other work were carried out in the high sand area.The geothermal geological conditions of the geothermal field in the high sand area were basically identified,and the geothermal anomaly area of the geothermal field in the high sand area was delineated to be 1.33 km^(2).The relationship between the occurrence conditions of geothermal fluid and lithology is clarified.The main burial depth of geothermal reservoir is 40.00~121.00 m.It is determined that the channel of geothermal flu⁃id is near north-south fracture and fissure karst cave development zone.The study provides an important basis for reserves calculation,exploration and development and long-term planning of geothermal resources in Gaosha area.
