北京地热资源勘查始于20世纪50年代中期。70年代初期，针对以往对地热资源的可再生性认识不足，不能真实反映地热资源中蕴含的可循环利用的热量，造成计算值偏小的情况。本文介绍了一种地热可再生资源量的新算法，计算每个热田的可再生资源量，从而重新估算北京市地热能的资源潜力。通过计算，采用对井抽灌方式且地热水100%回灌条件下抽灌井间距为300m时，10个地热田范围内地热能可提供的供暖面积为3.01亿m2；采用地热梯级利用（和热回收）结合其他辅助清洁能源调峰方式对建筑物进行供暖，全市热田面积内可供暖面积为8.60亿m2。对比传统地热可采资源量与本次研究采用的新算法，采用对井系统供暖可大大提高布井密度，使可供暖面积提高73倍。通过对地热能可再生资源量进行计算，对于推进全国范围内的地热发展，具有良好的推动作用。

Beijing geothermal resources exploration began in the mid of 1950s. The early 1970s, for the lack cognition to renewable characteristics of geothermal resources in the past, it cannot correctly relfect the recycled heat contained from geothermal resources, resulting in the calculated value being smaller. The paper describes a new algorithm of geothermal renewable resources to calculate renewable resource of each geothermal ifeld, thereby re-estimates geothermal resource potential in Beijing. By calculation, using the way of couple well pumping and at 100% recharge irrigation conditions with the well spacing of 300 meters, it can provide heating area of 301 million square meters in ten geothermal ifelds. The use of geothermal cascade utilization (and heat recovery) combined with other clean energy peaking mode for heating, the heating area of ten geothermal ifelds can attain 860 million square meters. Compared with the traditional geothermal recoverable resources and new algorithms in this study, the use of the couple well system can greatly improve the well spacing density and enhance 73 times of heating area. Through the geothermal renewable resource calculation, it plays a good role in promoting the geothermal development across the country.
