Enhanced Geothermal System Used For Deep Geothermal Power Generation Systems

摘要

The present invention relates to a deep geothermal power generation system using an artificial reservoir geothermal method. According to the present invention, the deep geothermal power generation system using the artificial reservoir geothermal method comprises a pump system and a power plant formed on the ground surface to generate electric power. According to the present invention, the deep geothermal power generation system using the artificial reservoir geothermal method further comprises: a supply unit connected to the pump system and extended from the ground surface to a geothermal heat collection layer placed in a deep position to supply water supplied from the pump system to the geothermal heat collection layer and to form an artificial reservoir with a geothermal water heated by the geothermal heat of the geothermal heat collection layer; a vertical production well distanced from the supply unit to be drilled from the ground surface down to the geothermal heat collection layer and to collect geothermal water of the artificial reservoir to the power plant through an operation of the pump system; and a radial down hole drilled from an end unit of the vertical production well towards an end unit of the supply unit to provide a collection path of geothermal water collected to the vertical production well and to be formed radially by being plural around the supply unit, thereby extending the collection path of the artificial reservoir. Accordingly, the present invention is able to reduce initial general costs since it is not needed to install a horizontal well, which is respectively installed on an injection well and a production well, in the artificial reservoir geothermal method, to allow the radial down hole radially formed on an end unit of the production well to improve connectivity of geothermal water introduced to the production well, and to minimize a volume of the geothermal water failed to be introduced into the production well, thereby maximizing the power generation efficiency and increasing the efficiency in generating electricity.
