Geothermal Reservoir Characteristics and Potential Evaluation of the Neogene Guantao Formation in North China:A Case Study of Tianjin
摘要
Abstract
Geothermal resources are a type of clean,green,low-carbon renewable energy with large reserves and wide distri-bution.Vigorously promoting geothermal energy development is of great significance to China in achieving its"dual carbon"goals and advancing the adjustment of the green energy structure.The Beijing-Tianjin-Hebei region is rich in geothermal re-sources.Analyzing the occurrence characteristics of thermal reservoir resources and accurately assessing geothermal resource reserves are important approaches to realizing the sustainable exploitation and utilization of geothermal resources and promot-ing the"dual carbon"initiative.From a geological structure perspective,the Guantao Formation spans multiple tectonic units.Its thermal reservoir consists of fluvial clastic rock deposits and is absent in some areas,with a total distribution area of 8 435.2 km² in Tianjin.Taking the Guantao Formation thermal reservoir in Tianjin as the primary research object,this study analyzes the spatial distribution and reservoir characteristics of the thermal reservoir and conducts in-depth investigations by comprehensively applying the thermal reservoir method and the injection-production balance method.The results show that the geothermal resource quantity of the Guantao Formation,calculated using the geothermal reservoir method,is 154.04×1018 J,equivalent to 52.56×108 t of standard coal,with a geothermal fluid storage capacity of 359.39×109 m3.For the injection-production balance method,the allowable annual exploitation volume of geothermal fluid,calculated based on the single-well exploitation right protection radius under reinjection conditions,is 4.112×108 m3/a,and the allowable annual exploitable heat energy is 679.37×1014 J/a.In addition,a comprehensive evaluation and zoning of the development and utilization potential of Guantao Formation geothermal resources are carried out,which provides key data support for the rational exploitation of geo-thermal resources in Tianjin and the Beijing-Tianjin-Hebei region.关键词
