摘要:
北京市地热资源属于沉积盆地型中低温地热资源,目前已有50年集中开发利用历史。经过多年开发利用,已突显出一系列问题。为合理确定北京市地热资源开发利用方向,服务首都城市功能,建设宜居城市,本文通过资料收集分析、野外地热地质补充调查及水化学取样,分析了北京地区地温场分布特征、水化学特征、同位素特征,其中研究表明热储顶板温度高于80℃的地区主要分布在北京凹陷中心和大兴迭隆起南部的凤河营附近;北京地区地热水化学类型主要为HCO3-Na型水。并开展了地热资源温度区划、地热资源开发利用方案区划及开发利用潜力区划。综合考虑地热田划分、地热资源特征、地热资源潜力区划,结合开采程度、资源条件及地区经济发展的需要,进行了地热资源保护区划,将其划分为限制开采区、控制开采区、鼓励开采区和其他地区,其面积分别为378.65 km2、562.88 km2、1612.07 km2、3722.31 km2。本文分析研究,对掌握北京市地热资源总体特征、了解地热流体补给来源、制定地热资源保护区划、合理开发利用地热资源具有重要指导意义。

Characteristics and regionalization of geothermal resources in Beijing

Abstract:
Geothermal resources in Beijing belong to middle-low temperature geothermal resources, which have experienced more than 50 years of concentrated development and utilization. After years of development and utilization, there have occurred some highlighted environmental geological problems in Beijing. In order to reasonably determine the direction of the development and utilization of geothermal resources in Beijing and to build a livable city, this paper summarizes the distributive characteristics of these resources by analyzing the features of geotemperature, hydrogeochemical and stable isotope characteristics. It is found that the geothermal reservoir with the roof temperature higher than 80oC is mainly located in the center of Beijing depression and near the Fengheying in the southern part of Daxing superimposed uplift, and the water chemistry type in Beijing is mainly HCO3~Na type. The authors also put up zonation for geotemperature regionalization, geothermal resources exploitation and utilization as well as potential regionalization. The geothermal resources protection regionalization is based on the division of the geothermal fields, the characteristics of geothermal resources in combination with the exploitation degree, resource conditions and regional economic development requirements. The region can be divided into restricted mining area, control mining area, mining area and other areas, with the respective area being 378.65 km2, 562.88, km2,1612.07 km2, and 3722.31 km2. The results obtained by the authors are of great significance for understanding the overall characteristics of the geothermal resources and the sources of geothermal water supply and for formulating the geothermal utilization planning. The results also has a guiding significance for protection and exploitation of geothermal resources.
