河北省集中开采区馆陶组热储可持续开发利用模式分析

Analysis of the sustainable development and utilization model of thermal storage in the Guantao Group,a concentrated mining area in Hebei Province

河北省地热资源富集,分布广泛,其中新近系馆陶组热储分布面积为5万km2,新近系馆陶组热储地热井占比高达56.68%,多用于冬季供暖。以河北省深州市、阜城县集中开采区为例,分析馆陶组热储的特点、以往开发利用模式与存在问题,结合政策要求与利用需求,提出适合于热水级以上(≥60℃)与温热水级(<60℃)的地热资源供暖方式下的开发利用模式,以期将地热资源利用率由50%~65%左右提高到81%~87%左右。促进地热清洁能源可持续发展,助力双碳目标实现。

Geothermal resources are abundant and widely distributed in Hebei Province,of which 50,000 are distributed in the thermal reserve of the Neoproterozoic Guantao Group,and 56.68%of the geothermal wells in the thermal reserve of the Neoproterozoic Guantao Group are mostly used for winter heating.Taking the centralized mining areas of Shenzhou City and Fucheng County in Hebei Province as examples,analyze the characteristics,previous development and utilization patterns and problems of the thermal storage of the Pavilion Guantao Group,combine policy requirements and utilization needs,and propose a development and utilization pattern suitable for geothermal resources heating methods above the hot water level(≥60)and warm water level(<60℃),with a view to increasing the utilization rate of geothermal resources from about 50%to 65%to about 81%to 87%.Promote the sustainable development of geothermal clean energy and help achieve the dual carbon goal.
