| Abstract | The Wumishan reservoir of the Jixian System (JXW) is one of the most exploited geothermal reservoirs in the Tianjin area. In this paper the characteristics of formation and existence of the reservoir is studied, based on regional geological data. The JXW or Jixian System covers all over the plain and mountain areas in Tianjin with continuous stable distribution, thick deposition, rich fissures and good water quality etc. Chemical and isotopic analysis indicate that the type of thermal fluids in JXW changes from HCO3-Ca•Mg in the north to Cl•SO4-Na in the south and takes on horizontal zoning characters, which is mainly influenced by the runoff and discharge of thermal fluids. |
