System and method of creating EGS having zonal injection wells

摘要

the present invention is constructed to determine the period-specific injection system and method for creating yijieseu about that, and more particularly, is, if you do complete the entire length of the geothermal production in open hole (Open Hole) and to the hydraulic fracturing, and some are only fracture zone is created, direct fracture (Short-circuit) with a high deep terrain is likely to be extended, Divide the entire length of a segment of the optimal number based on the direction and form generation and geothermal production characteristics of the fracture, yijieseu built only by open-hole completion of a piecewise constant infusion gakgae period (EGS: Enhanced Geothermal Systems) creating a which relates to a system and method. ; The present invention, in the entire length of dispersion fracture making possible to produce, by adjusting the injection pressure can be prevented from making direct the formation of fracture zone, to pull production provide a significant boost to the effect that the amount of geothermal energy, and also through the above effect, we hear so much more to create high performance yijieseu (EGS) in the Ministry unfold geothermal power, indigenous energy only to generate electricity By making, enhance our country's energy self-sufficiency, and provides a much reduced effect of making energy imports and greenhouse gas emissions.
