随着全球对清洁能源需求的增加，地热资源作为可再生能源受到广泛关注。该研究以开封市祥符区为例，评价了该地区地热资源的开发潜力及应用前景。研究表明：祥符区热储层的垂向温度场可分为变温带、恒温带和增温带，深度影响显著。地温梯度在500 m以深随深度增加而增大，500 m以浅逐渐降低。地热流体的化学成分分析显示，不同深度热储层间水化学类型差异明显，各热储层之间无显著水力联系。根据最大允许降深法和可采水量换算法，估算无回灌条件下地热流体可开采总量为9 390×10⁴ m³；在完全回灌条件下，地热流体可开采总量为360.7×10⁸ m³，开发潜力巨大。研究成果为祥符区地热资源的高效开发利用提供了科学依据和指导。

With the growing global demand for clean energy, geothermal resources as a renewable energy source have attracted widespread attention. This study evaluated the geothermal resource development potential and application prospects in the Xiangfu District of Kaifeng City. The results showed that the vertical temperature field of the thermal reservoir in the Xiangfu District could be divided into varying temperature zones, constant temperature zones, and increasing temperature zones, with depth significantly influencing the temperature distribution. The geothermal gradient increased with depth above 500 m and gradually decreased below 500 m. Chemical analysis of geothermal fluids showed significant differences in the water chemistry types between thermal reservoirs at different depths, with no significant hydraulic connection between the reservoirs. Based on the maximum allowable depth reduction method and the extracted water volume method, the total exploitable geothermal fluid without reinjection was estimated to be 9,390×10⁴ m³. Under complete reinjection conditions, the total exploitable geothermal fluid was estimated to be 360.7×10⁸ m³, indicating substantial development potential. These research findings provide a scientific basis and guidance for the efficient development and utilization of geothermal resources in the Xiangfu District.
