摘　　要：本文根据钻探资料和近年的勘查研究成果,结合部分已开发利用地热资源情况,对濮阳市地热资源的分布特征、赋存规律和地热田的结构进行了初步分析。指出濮阳市地热资源的分布在平面上可分为3个区,即西区、中区和东区。西区平均地温梯度为3 5℃/100m,地下热水主要储存于奥陶系马家沟组灰岩溶洞溶隙中,温度>60℃,而30～60℃的温水和温热水储存于上第三系明化镇组砂岩裂隙孔隙之中,埋深300～1080m;中区和东区的地热资源主要储存于上第三系馆陶组和明化镇组砂岩裂隙孔隙之中,中区平均地温梯度为3 2℃/100m,东区平均地温梯度为2 8℃/100m,地下热水埋藏深度在中区和东区依次加深。文中还对濮阳市地热田的储、盖、通、源等主要条件及其形成特征进行了论述。Based on recent exploration and exploitation data, characteristics of the occurrence of geothermal resources in geothermal fields in the city of Puyang are preliminarily analyzed in this paper. The geothermal resources can be found in the west, central and east areas in Puyang. The average geothermal gradient in the west area is 3.5℃/100m. Geothermal water with greater than 60 ℃ occurs mainly in the karstified limestone of the Majiagou Group of the Ordovician System, and geothermal water with 30～60 ℃ can be found in the porous and fractured sandstone of Minghuazhen Group in the Upper Tertiary, which ranges in depth from 300 to 1080 m. Geothermal water in the central and east areas is observed in the sandstone of Guantao and Minghuazhen Gropus in the Upper Tertiary. The average geothermal gradients in these two areas are 3.2 and 2.8 ℃/100 m, respectively. In addition, the formation of the geothermal water in Puyang is also discussed.
