Characteristic Of Geothermal Geology And Research Of Far-seeing Zone Of Geothermal Exploration In Pingzhuang Basin

Based on analysis of geologic foundation record about Pingzhuang basin, a lot of sino-foreign geothermal geology record and investigation of field geology, measuring of ground temperature in person and geo-chemical analysis of ascension spring, gushing water of fault, the fact that the anomaly of geothermal gradient of Pingzhuang basin, which is in region of low geothermal gradient, is caused by redistribution of conduction-oriented geothermal heat flow which is result from upheaval and depression of basin foundation bed is pointed out. After the field of ground temperature is simulated under the background of conduction-oriented geothermal heat flow by means of ANSYS, the characteristic of ground temperature distribution of top surface of basin foundation bed (Yixian team) is revealed. The sound condition of transmissibility fault and feeding water source, which are imperative in formation of the low-medium temperature geothermal system of convective type, is possessed in Pingzhuang basin. The low-medium temperature geothermal system of convective type is the main geothermal exploration object. Finally, a far-seeing zone of geothermal exploration is submitted in Chaoyanggou-Luotuoyingzi in the north of Pingzhuang basin.
