Medium-deep geothermal resources are widely distributed in China,with good resource endowment and large reserves.The current geothermal resource assessment methods are mainly used to evaluate shallow geothermal energy,and do not consider factors such as environmental carrying capability and extraction feasibility,making it difficult to guide the development of deep geothermal resources.This paper quantifies the development potential of medium and deep geothermal resources from multiple perspectives and applies the resource and environmental carrying capacity evaluation system to the evaluation of medium and deep geothermal resources.This study system integrates three types of factors including geothermal resource endowment,environmental impact,and socio-economic and technical conditions,takes into account factors such as thermal reservoir depth and temperature,and combines hierarchical analysis and statistics to clarify the grading indexes and weight assignments.Based on the evaluation system of medium-deep geothermal resources proposed in this paper,the potential and prospect of medium-deep geothermal resources in typical regions are evaluated,which can provide theoretical guidance for the development of medium-deep geothermal resources.
