<p>PURPOSE:To predict a maximum shut-off pressure and a maximum temperature of a geothermal pile well. CONSTITUTION:The length of a liquid phase 6 in a geothermal pile well 1 is calculated from a pressure acting upon the geothermal pile well 1 and the specific weight of geothermal fluid flowing into the geothermal well 1. Further, it is calculated from the depth of a feed pump in the well 1, the density and specific enthalpy of the geothermal. Further, the inflow temperature of the geothermal fluid at which the thus calculated lengths of the liquid phase concede with each other, is obtained, and the pressure in the pile well 1 at that temperature is calculated.</p> |
