| 摘 要： | 建立了地热热储二维分布模型，对地热生产过程中地热热储的压力响应和冷却效应进行了数值模拟，提出了利用地热尾水回灌和井内换热相结合的新型对井系统。该系统采用采水井内换热器和地面套管式换热器，既可节省保温费用，又可减少散热损失。根据井筒传热模型，建立了井内换热器优化设计方法，得出了井内换热器的最佳长度为360m。

| Abstract: | A two-dimensional distributed parameter model of geothermal reservoir was established. The pressure maintenance and temperature cooling effect of geothermal reservoir were predicted by numerical simulation. A new-type couple-well heating system was put forward to adopt the techniques of the re-injection of geothermal exhaust water and the heat-exchanger in well bore. The system can save insulating cost and reduce heat loss using heat exchanger in well bore and casing heat-exchanger on surface. Based on well bore heat transfer model, an optimal design method of heat-exchanger in well bore was given, and the optimal length of the heat-exchanger in well bore was 360 metres, |
