中国雄安新区地热资源丰富。然而，热状态和地热能聚集机制尚不清楚。根据地质条件和现今地温场特征，建立了2D模型，分析了幔源热传导过程，预测了深部地温场的分布。荣成隆起和牛驼镇隆起的大地热流分别为64和75 mW/m2。该区地热资源受热传导、构造隆起、深部大裂缝和储层内对流四要素控制。
There are abundant geothermal resources in the Xiong'an New Area, China. However, the thermal state and geothermal energy accumulation mechanism are not clear. Based on the geological conditions and the characteristics of the present geothermal field, a 2D model was established to analyze the process of mantle-derived heat conduction and to predict the distribution of the deep geothermal field. We calculated the terrestrial heat flow for the Rongcheng uplift and Niutuozhen uplift to be 64 and 75 mW/m(2), respectively. The geothermal resources in this area are controlled by a four-element model comprising heat conduction, structural uplift, large deep fractures, and convection within the reservoir.
