| 中文摘要:天津地热在开采的同时重视回灌，有效地保护了宝贵的地热资源。天津在基岩裂隙型地热中回灌效果良好，但馆陶组地热井回灌量欠佳，为了解决这一问题，进行了研究探索。介绍了采用射孔工艺成井，在保证取水效果的同时，使稳定无压回灌量达到了101 m3/h，取得了很好的效果。 |

| Abstract:The recirculation being paid attention in the geothermal exploitation can effectively protect the valuable geothermal resources. Recirculation effects are good in bedrock fracture geothermal exploitation in Tianjin, but not in Guantao formation, on which the pertinence study is made. The paper introduces the perforating technology in well completion, stable non-pressure recirculation volume reaches to 101m3/h with water taking effect being ensured at the same time. |
