The Cascaded Utilization of Geothermal Resources

The geothermal resource is a clean complex resource, which can be changed into sustainable energy guided by the science theories. Demonstrating the heating engineering of a immigration village in Tianjin, the intention of this paper is to survey the sustainable utilization of geothermal resource meeting basic heating load, containing: (1) the dynamic prediction technologies of the production–reinjection of geothermal wells; (2) the design of inclined geothermal well; (3) the technologies of cascaded utilization of geothermal resource; and (4) the project appraisal. The results show geothermal resource is sustainable, and yield good economic returns and social benefits.
