Geothermal resources is one of the most practical and competitive new energy at present，and there is abundant geothermal resources in the new coastal region． The article get the three following conclusion through the geothermal geological condition by the drilling strata and the condition of the reducing test: stratigraphic division is done by the analysis of formation lithology and the drilling aging; the water yield is higher than 100 m3 /h，the flow temperature is 67℃--71℃; the average geothermal gradient of the overlying strata is 3. 08℃-- 3. 33℃ /100 m．
