WS01 well is located in the south of Wenshang County. It was completed in August 2017 with a depth of 2 269.28 m .The thermal reservoir type is Ordovician limestone thermal reservoir.The water intake intervals are 1 977.90 ~2 008.10 m,2 008.10~2 027.30 m,2 027.30~2 043.00 m,2 102.55~2 123.90 m,2 154.85~2 165.00 m,and the cumulative thickness is 96.6 m.The average temperature of wellhead outlet is 61 ℃,and the water output is 764.16 m^3 /d when the depth is 210.054 m,and the recoverable heat of a single well is 1.41×10^5 MJ/d. The geothermal water has a pH value of 6.69,The mineralization degree is 24 929.3 mg/L and the hydrochemical type is Cl-Na·Ca. It can be named as strontium bromide type hot mineral water containing iodine lithium metaborate metasilicate. It is suggested that the direction of development and utilization should be for therapeutic bathing.
