Characteristics and genesis mechanism of deep geothermal resources in the North Jiangsu Basin, East China

Abstract

Geothermal resources have been recognized as an important component of clean and renewable energy, and the exploration, development, and utilization of geothermal resources, especially deep geothermal resources, are of great significance to achieve carbon capping and carbon neutrality. This study reviews the exploration process of deep geothermal resources in the North Jiangsu Basin (NJB) as an example and presents the latest results with the latest data. The study shows that the NJB is a typical heat basin with an average heat flow value of 68 mW/m2; the favorable deep geothermal resource areas in the NJB are mainly distributed in depressions (especially those near the Jianhu Uplift), rather than the Jianhu Uplift; the genesis mechanism of the favorable deep geothermal resource areas in the NJB can be summarized as two times, two sources thermal concentration. It provides not only an important possible model for future geothermal resource utilization in the Yangtze River Delta region but also a new idea for the study of geothermal characteristics and genesis mechanisms in East China.
