Problems solved by technology

Furthermore, these modern attempts to commercialize HDR geothermal production are economically limited by the high cost of drilling injection wells and multiple production wells
The high cost of the wellbore severely constrains the project design to be an optimal production system that exploits the maximum thermal energy in the host rock

Embodiment Construction

[0040] The present invention will be described more fully below with reference to the accompanying drawings showing preferred embodiments of the invention. However, the invention may be embodied in many different forms and its construction should not be limited to the embodiments shown herein; rather, these embodiments are provided so that those skilled in the art will That this disclosure was thorough and complete, it fully conveys the scope of the invention.

[0041] The present invention utilizes a dispersed system of expandable fractures in a hot rock formation, and the subsequent elastic cycle of "expansion" and "contraction" of the reservoir through the injection and recovery of injected fluid (such as water), thereby extracting from the hot rock formation Based on advances in heat extraction. Seams in the formation will open as fluid (eg, water) is injected into the wellbore to increase reservoir pressure. The seams in the formation will close as the reservoir pressur...

Abstract

The present invention relates to a method and system for extracting and / or utilizing thermal energy from rock formations. This Abstract is provided to comply with rules requiring an Abstract that allows a searcher or other reader to quickly ascertain subject matter of the technical disclosure. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

Description

technical field [0001] The present invention relates to the drilling of well bores, methods of completing well drilling and the extraction and / or utilization of thermal energy from formations beneath the earth's surface. Background technique [0002] Permeable geological formations with high temperatures have been found in many specific locations around the globe. When rainwater seeps through the ground and into these rock formations, it is heated and can flow to the surface as springs and hot springs. High temperature impermeable geological formations (typically Precambrian formations) are found almost all over the globe, and they are usually located at deeper depths than high temperature permeable formations, which are usually sedimentary rocks in nature. These impermeable Precambrian rock formations are generally considered to be quite dry, and heat can be recovered from them by the hot dry rock (HDR) geothermal production method, in which water is pumped into a well (th...
