| 摘 要： | 在地热开发过程中经常遇到如下问题：热储压力随开采量和时间的增加而降低，地热尾水排放造成热污染和资源浪费等。回灌是解决上述问题的有效方法。针对回灌过程中渗流场的动态变化，建立地热回灌渗流场数学模型，推导了渗透系数恒定与变化时不同条件下的单井回灌公式。实例分析表明：所得公式能够表征回灌渗流场中各变量之间的相互关系，可以解释和预测回灌过程中水头与流量的变化趋势。 |

| Abstract: | The pressure of geothermal reservoir declines as volumes of geothermal water is pumped,and heat pollution and waste of resource are caused by discarded geothermal water during the process of geothermal exploitation. Geothermal reinjection is one of the best method to solve the problems. The seepage field is dynamic while water into reinjection well. The model of seepage field for geothermal reinjection is established. Under the conditions of constant hydraulic conductivity and variable hydraulic conductivity,calculation formulas for single reinjection well are obtained. The results from example analysis show these formulas can express the relation of variable depending on the seepage field. The model can be used to explain and protest the trend of pressure and reinjection activities. |
