Achievements and prospects of exploitation, utilization and management of geothermal resources in Tianjin

This paper is the results of geothermal resources exploration, utilization and management.Objective Tianjin's geothermal resource endowment has outstanding advantages, and it is in a leading position in geothermal exploration, development, protection and management in China. However, under the background of the construction of ecological civilization, the security of energy resources and the realization of the goal of " double carbon, " the utilization and management of geothermal resources are still deficiency, which needs further research and discussion. Methods Based on the history and achievements of the utilization of geothermal resources in Tianjin, this paper discusses the current situation and existing problems of the utilization of geothermal resources, clarifies the challenges faced by geothermal management, and puts forward specific countermeasures and methods to scientifically guide the sustainable utilization. Results In the future, the control degree of geothermal exploration in Tianjin should be improved, and the geothermal resources of 4 000~6 000 m should be found out to ensure the supply of resources; Key technologies such as prevention and control of sandstone pore-type reinjection attenuation, reservoir reconstruction and injection of exogenous water should be strengthened to improve resource carrying capacity; It is necessary to promote multi-energy combination, grid-connected interconnection, reduce tail water temperature, improve heat supply efficiency and increase heat supply capacity; Strengthen the unity, integrity and guidance of geothermal resource management, and create a policy environment conducive to the development and utilization of geothermal resources. ConclusionsTianjin has a long history of geothermal exploration, and the method is perfect. Geothermal development and protection are equally important, and the management system is increasingly standardized, which has played a leading role in the national geothermal exploration. In the future, we should improve the degree of exploration and tap the deep geothermal resources; Break through the technical difficulties of sandstone reservoir reinjection attenuation, reasonably set the layout and development mode of geothermal resources utilization.Improve the life cycle management mechanism of geothermal wells, innovate the management mode of geothermal resources, and promote the healthy and orderly development of geothermal industry.
