| Renewal Characteristics and Basis of the Geothermal Water Resources in Middle Hebei Plain: A Case Study of the Guantao Formation Underground Geothermal Water System |
| To tackle the problem of the geothermal water resources updatable characteristics in the Guantao Formation of the middle Hebei plain, the authors adopted the identification method of abnormal variation of the geothermal water level under the same pumping intensity to study the characteristics of annual and monthly decline of the geothermal water level in response to the pumping and annual precipitation in the upper reaches of the geothermal water system since 2000. Some conclusions have been reached: (1) The geothermal water resources of Guantao Formation has a certain renewable capability, which is related to such factors as the variation of annual precipitation in the upper area of the geothermal water system, the buried depth, the decline range of the geothermal water level, and the ratio between the coarse sandstone and the fine sandstone in the decline range; (2) Large-scale exploitation of the geothermal water in the Guantao Formation is a necessary condition of being recharged from lateral inflow recharge in the upper reaches of the geothermal water system; it belongs to the pumping induced recharge, and the number of the recharge resources is not large; (3) The trend of the geothermal water level since 2000 shows that the geothermal water system has been in overdraft state, and hence it is necessary to increase the supply of pressure or artificial recharge; otherwise, the sustainable development and utilization seem to be very difficult or even impossible. |
