Based on the newly measured borehole temperature logs from 22 wells and other researchers' data,we analyze geothermal field features in Xiongxian,and find that the transfer model is mainly conductive in the cap rock,but the thermal reservoir is mainly convective due to the forced convection resulted by geothermal production and recharge. Several borehole temperature measurements show that the length of well static time and the migration patterns in well control the temperature distribution and the dynamic changes in the borehole: with more time to keep well static,the temperature data inversely changes in the neutral point. The temperature profile is different between the production and the recharge wells. The temperature of Quaternary bottom in Xiongxian geothermal field is 32.8 ℃～48 ℃,and the Rongcheng uplift is 28 ℃～35 ℃. The temperature of Tertiary bottom in Xiongxian geothermal field is 64.5 ℃～81.29 ℃,and the Rongcheng uplift is 45 ℃～60 ℃. The geothermal gradient of cap rock in Xiongxian geothermal field is between 43.9 ℃/km and 72.2 ℃/km,the average value is 51 ℃/km. The Rongcheng uplift is between 31.4 ℃/km and 41.1 ℃/km,the average value is 37.1 ℃/km. The geothermal flow in Xiongxian geothermal field is between 80.61 mW/m2 and 113.86 mW/m2. It is the highest geothermal flow in Jizhong depression.
