摘　　要：柘城县城区地处在近年最先勘查发现的胡襄煤田内的南部边缘地段。区内地层属华北地台型沉积,自下而上发育有寒武系、奥陶系、石炭系、二叠系、新近系和第四系,其中,石炭系上统太原组和奥陶系中统为区内重要的热储集层,该热储层蕴藏着丰富的热能及热水能源,具有广泛的适用性和良好的开发利用前景。依据勘查钻孔资料,阐述了区内地质、构造特征;利用钻孔测温资料,分析研究了地温、地温场、热储层的分布特征;给出了热储层的深度和温度范围;圈定了柘城城区西北角为地热异常地段,并分析了地热异常地段的控热构造特征或成因;提出了开发利用地热资源的优选地段及深度范围,为地方经济发展、合理开发、高效利用地热资源,提供了第一手资料依据。Zhecheng county is located in the southern fringe of the Huxiang Coalfield, which was first explored in recent years. The strata in this area belong to the North China platform deposit, and Cambrian, Ordovician, Carboniferous, Permian, Neogene and Quaternary are developed from bottom to top. Among them, the upper Carboniferous Taiyuan and Ordovician are important thermal reservoirs in this are- a, which contain abundant thermal energy and hot water energy, and have wide applicability and applicability, with good prospects for development and utilization. Based on the data of exploration boreholes, this paper expounds the geological and structural characteristics of the area, to analyze and study the distribution characteristics of geothermal, geothermal field and thermal reservoir by using borehole temperature measurement data, to give the depth and temperature range of the thermal reservoir, delineated the northwest corner of Zhecheng City as the geothermal anomaly section, and to analyze the thermal control structure of the geothermal anomaly section. Geo- thermal resources can be exploited and utilized in a reasonable way, which provided a first-hand basis for local economic development, rational development and efficient utilization of geothermal resources.
