| 中文摘要:无干扰地下换热井是利用中深部地层自然地温对循环介质预加热，实现冬季供暖辅助加热，达到节能减排效果。该循环系统为闭式循环，利用密闭的金属换热器，只取热不取水，是一种绿色的供暖方式。由于环保、清洁低碳、无污染等特点，将是北方地区清洁供暖的重要技术手段之一。介绍了该型换热系统及完井工艺。 |

| Abstract:The concept of the interference-free underground heat exchange well is to pre-heat the circulating medium with the natural ground heat in mid-deep to deep wells and provide auxiliary heating in winter, achieving energy conservation. It is a closed loop system with the sealed metal heat exchanger and a kind of green heating method, since it recovers only heat without consuming water. With the features of environmental protection, cleanliness and low carbon without pollution, it will be one of the most important means for clean heating in north China. This paper presents the heat exchange system and the completion technology. |
