Abstract

Interference-free geothermal development is a closed cycle system. The Circulating medium extracts heat from geothermal reservoir by sealed pipe. Interference-free geothermal development just takes heat without groundwater. At present, the research on non-interference geothermal development is in its infancy, and a mature calculation model has not yet been formed. Based on drilling hydraulics and combined with pipe heat transfer, this paper modularizes underground pipes for geo-thermal development, and establishes a set of pressure drop and heat transfer calculation models for interference-free geothermal development by means of infinitesimal segment. Apply C # for software development. The model established in this paper is used to calculate the pressure drop and heat transfer of the double-butt U-shaped well on Xi’an Depression. The results show that this research can provide a certain theoretical basis for calculation of pressure drop and heat transfer in the process of Interference-free geothermal development.
