GEOTHERMAL ENERGY COLLECTING METHOD

摘要

A method of collecting geothermal energy includes removing cuttings from a bore hole by circulating a medium through the bore hole while a bit penetrates the earth by being rotated, thereafter obtaining a geothermal production well by inserting a casing pipe into the bore hole of the well, carrying out a scaling prevention treatment, drawing out a geothermal fluid from the production well and utilizing energy possessed by the geothermal fluid upon conveying the fluid to a predetermined location.
