摘要:
河北四家地热异常区地势西北高、东南低，地热资源丰富。为了科学保护、合理利用该地热资源，以地热异常为研究对象，采用地温场测量、水化学及同位素测试、地球物理测量等方法手段，探讨了四家地热异常区地热资源形成机制、赋存环境及循环机理。研究表明，该地热异常区内地热井水位埋深介于-0.94~3.02 m之间，水位埋深浅; 异常中心以垂直向上对流传热为主，异常外围以传导传热为主，深部热流沿异常中心的断裂交会处上升，并产生横向迁移、扩散，在一定范围内储存起来，形成了本区的地热异常。可控源音频大地点测测深剖面解译成果表明，四家地区深部花岗岩体被切割，使深部的热流能够沿断裂上升，混合并加热赋存于四家地热异常区下部，形成该区域的地热异常。水质分析结果表明，四家地区地热流体水化学类型主要为SO42--Na+型，F-、SiO2含量与水温呈良好的正相关关系，同时F-、SiO2质量浓度严格受地温场的控制。四家地区地下热水为大气降水补给，属大气成因，区内地下热水氚值较低，为0.6~0.8T.U，通过研究认为本区地下热水年龄大于30 a。研究成果为今后在冀东及类似山区开展地热资源勘查研究具有指导意义。
Abstract:Sijia geothermal anomaly with lot geothermal energy is located in the northwestern part of Qinglong of Hebei Province.In this paper, in order to protect and utilize the geothermal resources scientifically, the geothermal anomaly is studied by means of geothermal field measurement, hydrochemistry and isotope measurement, geophysics measurement, etc. The formation mechanism, occurrence environment and circulation mechanism of geothermal resources in four abnormal geothermal areas are discussed for the first time.According to the study of this area, it is found that the buried depth of geothermal wells in the four geothermal anomalies ranges from -0.94 m to 3.02 m, which is characterized by the shallow depth of the water level.The center of the anomaly in the area is dominated by vertical upward convective heat transfer, and the periphery of the anomaly is dominated by conductive heat transfer.The deep heat flow rises along the fault junction of the anomaly center and generates lateral migration and diffusion.It is stored within a certain range and formed geothermal anomalies in this area.The interpretation results of the CSAMT show that the deep granite body in this area is cut, so that the deep heat flow can rise along the fault, and mixed and heated to the bottom of the Sijia geothermal anomaly areas to form geothermal anomalies in the area.The results of water quality analysis indicated that the hydro-chemical type of the geothermal fluid in this area is mainly SO42--Na+ type, F- and SiO2 content both have a good positive correlation with water temperature, and those mass concentration are strictly controlled by the ground temperature field.The underground hot water in this area is replenished by atmospheric precipitation, which is the cause of the atmosphere.The value of 3H of the underground hot water in the area is low, ranging from 0.6 T.U to 0.8 T.U, which directive considers that the underground hot water in this area is older than 30 years.The achievement of these results will lead the geothermal resources exploration in eastern Hebei and similar mountainous areas.
