摘　　要：应用广域电磁法对郑州地区深部寒武-奥陶系岩溶型热储进行探测研究,共布设了4条NNE向广域电磁测深剖面,获得了415个测深点。通过对广域电磁测深数据的处理、分析和反演,获得了研究区内4000 m以浅的二维电性结构模型。综合区域地质资料,地层由新到老依次划分为第四系-新近系、三叠系、二叠系-石炭系、奥陶系-寒武系、元古界。推断了新郑-太康断裂、大隗镇断裂、张庄断裂、推断断裂F4和李粮店断裂的位置、产状等信息。其中,新郑-太康断裂为新郑凸起与薛店-尉氏南次凹带的分界断裂,控制了三叠系沉积。基于地层和断裂分布特征,推断了7个深部寒武-奥陶系岩溶型热储的有利部位,认为位于新郑-太康断裂的DR1热储部位成热条件最好。The wide field electromagnetic method was used to detect and study the deep Cambrian-Ordovician karst heat storage in Zhengzhou area.A total of four NNE-trending wide field electromagnetic sounding profiles were set up,and 415 sounding points were obtained.Through the processing,analysis and inversion of the wide field electromagnetic sounding data,a two-dimensional electrical structure model with a depth of 4000 m in the study area was obtained.Based on regional geological data,the strata are divided into Quaternary-Neogene,Triassic,Permian-Carboniferous,Ordovician-Cambrian,and Proterozoic from top to bottom.The location and occurrence of the Xinzheng-Taikang fault,Daweiizhen fault,Zhangzhuang fault,the inferred faults F4 and the Liliangdian fault were inferred.Among them,the Xinzheng-Taikang fault is the boundary fault between the Xinzheng uplift and the Xuedian-Weishi southern sub-sag belt,which controls the Triassic deposition.Based on the characteristics of strata and fault distribution,seven favorable locations of deep Cambrian-Ordovician karst heat storage were inferred.It is considered that the DR1 thermal reservoir position located in Xinzheng-Taikang fault has the best thermal conditions.
