运用“指标法”进行浅层地温能适宜性分区可行性探讨

Using the index method to carry out the suitability partition of shallow geothermal energy

本文介绍了吉林省浅层地温能利用现状及存在的问题。从工作实际出发,在浅层地温能调查评价中,运用《浅层地温能调查评价规范》的指标法对水源热泵的适宜性进行评价不完全正确。在对水源热泵应用现状调查中发现仅用运用指标法中灌采比分类确定地下水源热泵的适宜性欠妥当。即使灌采比小于50%(不适宜区),但采用抽一灌二、或抽一灌三,回灌效果良好,基本上可以利用,这一点应当引起人们的重视。指标法在有些地区应用效果较好。

In this paper, the writer introduces the present situation and problems of shallow geothermal energy utilization in Jilin Province. On the basis of working practice, in the evaluation of shallow geothermal energy, to evaluate the suitability of the water source heat pump by using Index method of evaluation criterion of shallow geothermal energy survey is not entirely correct. In the application investigation of water source heat pump, it is found improper that the suitability of the underground water source heat pump is determined by using injection pumping ratio classify of the index method. Even if the injection pumping ratio is less than 50% （unsuitable area）, to use pumping one injection two, or pumping one injection three, the effect is good, can be used, which should be paid attention to. The index method is effective in some areas.
