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

Also the theoretical basis of the method have been checked through simple deducing simulation and the influences of various physical parameters on the method have been studied. it is shown that the method is theoretically reliable for the production oil wells without very high production rate and is more suitable in field production for oil wells ( i ) in area with bigger geothermal gradient ; ( ii ) producing fluids ( oil and water ) with distinguish thermal characteristics ; ( iii ) producing oil with lower heat capacity or water with higher heat capacity ; ( iv ) with good surface measurement accuracy, as well as the method h as certain requirements on the accuracy of the temperature and flowmeter logs sensors
