| 摘 要： | 电磁阵列剖面（EMAP）方法是深部地球物理方法中必不可少的手段，与高密度电法类似．它也是一种阵列勘探方法．其资料反演须计算稚可比偏导数矩阵，对于二维模型其反演计算量大．误差难干控制。研究使用高密度电阻率反演方法对EMAP资料进行处理解释．并与常规二维反演结果进行对比．发现这种应用不仅可行，而且运算量大大降低、误差可以控制，并且在确定目标体横向电阻率的差异和断层位置以及确定高阻基底的深度上效果更好。

| Abstract: | Electromagnetic Method of Arrangement Profile(EMAP) was an essential instrument which was necessary in deep geophysical method.It was also a method of array exploration similar to high-density resistivity.It was necessary to compute Jacobi differential coefficient matrix in EMAP datum inversion.For 2-D model,its inversion calculation was very great.Its error was difficult to control.High-density resistivity was used to interpret EMAP data and contrast it with general OCCAM 2-D inversion result,and it is not... |
