Abstract:Shallow geothermal energy is green renewable energy. If it is widely used, it can greatly reduce the energy consumption of urban buildings and relieve the pressure of urban environmental protection. Through field thermal response test, thermophysical property test, hydrogeological drilling and investigation, the thermophysical parameters, hydrogeological conditions, geothermal field characteristics and shallow geothermal storage conditions of the strata in the working area have been identified. Combining with AHP and index method, the suitability zoning has been carried out, and the following research results have been obtained. The shallow geothermal energy in the working area is mainly distributed in the deep clay, sand and bedrock. The average thermal conductivity of the borehole is 2.11w/m·K, and the average heat exchange is 42.53W/m. The suitable area of ground water heat pump in the working area is 0.995km2, the medium suitable area is 29.21km2 and the unsuitable area is 34.795km2. The suitable area of ground heat pump is 59.886km2, and the unsuitable area is 4.94km2.
