| Abstract: | With the gradually increasing development of deep geothermal reservoir in Tianjin area, it becomes more difficult for geothermal well drilling construction as serious leakage formations should be drilled through. Therefore, a set of air-lift reverse circulation drilling system with suspension type independent inner pipe is developed. In combination with the engineering examples of 2 geothermal wells in Tianjin area, the paper introduces this drilling system and analyzes the application effects in deep geothermal wells construction. |
