摘要
本文以北京市朝阳区姚家园公园地热井为例,利用该井的抽水试验数据、水质化验数据和其它相关成井数据,通过适当的方法评价了该地热井地热资源利用情况,求取了该地热井含水层的渗透系数,以合理的方法确定该地热井的影响半径和地热井的保护范围。通过对该地热井热储量的计算与评价、热水的腐蚀性、结垢和起泡的评价、投资成本与回收效益方面的研究,对量化评价单个地热井的一些关键的技术和经济指标进行了探讨,为评价地热井效益提供了一种参考模式。
This paper takes the geothermal well in Yaojiayuan Park of Chaoyang District in Beijing as an example, and uses the pumping test data, water quality testing data and other related data of this well, evaluates utilization conditions of the geothermal resources of this well through appropriate methods, obtains the aquifer permeability coeffi cient of this geothermal well. Through a reasonable way, this paper ascertains the infl uence radius and the scope of protection of the well, probes quantitative evaluations what are about some key technical and economic indexes through geothermal heat storage calculation, corrosion, scaling, foaming evaluation, investment, costs and benefi ts of recycling research, provides a reference model for evaluating the benefi ts of geothermal well.
