河北省环首都县市区地热温泉资源赋存特征与潜力评价

Evaluation of the occurrence characteristics and potential of geothermal hot spring resources in counties, cities, and districts of Hebei Province surrounding capital Beijing

摘要

摘要:
研究目的 河北省地热温泉资源广泛分布，储量丰富，地热资源作为一种清洁可再生能源，具有较高的开发利用价值。对环首都县市区地热资源进行系统调查评价可为河北省打造环首都康养产业提供科学依据，助力实现“建设京畿福地、老有颐养的乐享河北”目标。
研究方法 通过对环首都各县市进行地热地质测量、水文地球化学测量以及收集相关资料，系统论述了环首都14个县市区地热地质条件、地热流体特征，总结环首都地热资源概况和分布特征，分析断裂对流型和盆地传导型地热资源的赋存条件，对地热资源量及开采潜力进行评价。
研究结果 环首都县市区地热资源主要分为带状热储、层状热储及复合型热储三类，带状热储中大部分地热田的水化学类型为SO₄−Na型水，层状热储中地热流体主要为HCO₃−Na型水。该区地热资源量达2241.56×10⁴ m³/a，可开采热量为5.58×10¹⁵ kJ/a，相当于燃煤18.29×10⁴ t/a。通过潜力分析，环首都绝大部分县市区地热资源极具开发潜力，共有赤城县、遵化市等9处属极具开发潜力区。
结论环首都周边地热资源较丰富，但开发利用程度较低，需进一步采取政策引导、产业规划以推动地热资源的勘查开发利用，为环首都康养产业的建立提供资源保障。

Objective Geothermal hot spring resources in Hebei Province are widely distributed and abundant, and geothermal resources have high development and utilization value as a clean and renewable energy source. Conducting a systematic investigation and evaluation of geothermal resources in counties and urban areas surrounding the capital can provide a scientific basis for Hebei Province to develop a wellness industry around the capital, aiding in achieving the goal of 'building a blessed land around Beijing where the elderly can enjoy care and leisure in Hebei.'
Methods Based on the geothermal geological measurements, hydrogeochemical measurements, and the collection of relevant data, the geothermal geological conditions and geothermal fluid characteristics of 14 counties and cities around the capital were systematically discussed, the general situation and distribution characteristics of geothermal resources in the capital were summarized, the occurrence conditions of tectonic convection and basin conduction geothermal resources were analyzed, and the geothermal resources and exploitation potential were evaluated.
Results The geothermal resources in the counties, cities, and districts of Hebei Province surrounding capital Beijing are mainly divided into three categories: zonal heat storage, layered heat storage, and composite heat storage, and the hydrochemical type of most geothermal fields in the zonal heat storage is SO₄−Na water, and the geothermal fluid in the layered heat storage is mainly HCO₃−Na water. The geothermal resources in this area are 2241.56×10⁴ m³/a, and the recoverable heat is 5.58×10¹⁵ kJ/a, which is equivalent to 18.29×10⁴ t/a of coal. Through the potential analysis, the geothermal resources of most counties and cities around the capital have great development potential, and there are 9 areas with great development potential, including Chicheng County and Zunhua City.
Conclusions The geothermal resources around capital Beijing are abundant, but the degree of development and utilization is low. It is necessary to further adopt policy guidance and industrial planning to promote the exploration, development and utilization of geothermal resources, providing resource guarantee for the establishment of the health care industry around the capital.
