To quantitatively assess the quality of deep hydrothermal geothermal resources in the target area

with a focus on middle-deep hydrothermal resources in sedimentary basins

a comprehensive analysis is conducted. This analysis delves into the effects of geothermal geological conditions

the nature of the geothermal resources themselves

and the quality of geothermal fluids on the overall resource quality. For this assessment

sixteen indicators that significantly impact the quality of geothermal resources are identified. These indicators are then incorporated into an Analytic Hierarchy Process（AHP） framework

which assigns weights to each indicator

facilitating a quantitative evaluation. The middle-deep hydrothermal geothermal resources are divided into three levels and seven categories. Level Ⅰ areas are resource advantage areas that can be efficiently developed; Level Ⅱ areas are resource rich areas that meet the requirements of industrial development; Level Ⅲ areas are resource non enriched areas. Ultimately

a quantifiable resource evaluation system is formed to provide data analysis conclusions on whether geothermal resources can be utilized. The relevance and practicality of this evaluation system are demonstrated through its application in a case study. The example of geothermal development and usage in the Caofeidian District of Tangshan City

Hebei Province

serves as a testament to the system's effectiveness in guiding decision-making processes for geothermal resource utilization.
