| 中文摘要:在新开发的利用地热井供暖系统中，需要通过多次多井的回灌实验，提取更为精确的回灌数据，从而选取最佳回灌井。地热井使用一段时间后，需通过采灌互倒的形式，调整灌井与采井。传统的回灌装置设置以建设项目为主导，不能较好的统筹考虑钻探施工、地热井钻井工艺构造、前期的回灌试验验证和使用过程中的地热井维护等因素，此外，固定式回灌装置存在占地面积大，投资代价高，安装维护复杂等问题。为此，研制了一种移动式地热尾水回灌装置，此装置结构简单，能够实现整体移动、快速安装、快速转场，提供多级过滤并辅助加压的回灌方式。 |

| Abstract:In the newly developed geothermal well heating system， it is necessary to obtain more accurate reinjection data through multiple well reinjection experiments， so as to select the best reinjection well. After the geothermal well has been used for some time， the injection well and the production well are reversed. The traditional placement of the reinjection device is more like part of a building project， thus， without proper consideration of drilling operation， geothermal well drilling technology structure， early reinjection test verification， geothermal well maintenance and other factors. There are also some problems with the fixed reinjection device such as large footing area， high cost of investment， complex installation and maintenance. As a result， a mobile geothermal tail water reinjection device is designed and manufactured. This device is featured of simple structure， movement as one piece， rapid installation and transfer as well as multi-level filtration and auxiliary pressurized reinjection. |
