| 摘 要： | 在河南省开封凹陷区地热资源调查评价工作中,采用大地电磁测深法,通过对2条剖面(50个测点)的资料分析,采用有效视电阻率数据对剖面进行反演处理,继而从电性特征方面查明区内断裂构造的发育状况,划分重要地质界面,了解基底起伏及地层富水性,圈定出本区地热异常范围。

| Abstract: | In the investigation and evaluation of geothermal resources in Kaifeng depression,the authors employed magnetotelluric sounding method and,through an analysis of data obtained from 50 measuring points along two profiles,performed inverse processing of the profiles according to effective apparent resistivity data.On such a basis,the conditions of fault structures in this area were found out in terms of their electrical character,important geological boundaries were recognized,the basement undulation and wate... |
