The technology of hydraulic fracturing and reservoir construction in Hot Dry Rock (HDR) is crucial in the development of geothermal energy. This technique involves the injection of high-pressure fluid into the underground HDR formations to create a network of fractures, enhancing the permeability of the reservoir and significantly improving the efficiency of heat extraction and the utilization range of geothermal resources. The specific operation includes drilling into the target HDR layer, injecting high-pressure water to create a network of fractures, enhancing permeability for the circulation of geothermal fluids. Cold water is injected underground, undergoes heat exchange, and then extracted to the surface through production wells for electricity generation or heating. The hydraulic fracturing and reservoir construction technology in HDR is not only suitable for traditional geothermal energy-deficient areas but can also be widely applied in regions with abundant HDR, further promoting the sustainable development of the geothermal energy industry. With continuous technological advancements, the efficiency of hydraulic fracturing and the stability of reservoirs continue to improve, and the associated environmental impacts are gradually reduced, reflecting the development concept of emphasizing both technology and environmental protection.

Furthermore, the promotion of this technology has stimulated the development of related industrial chains, enhancing the overall efficiency and economic viability of geothermal energy development and utilization, providing strong support for the transformation to green energy.
