摘　　要：利用有限差分法建立二维模型,通过利用傅里叶变换将磁偶极子源沿激发方向变换为一组线电流源,将问题变为频域问题,在数学上进行简化,减少了大量未知数,降低计算成本。In resistivity logging, the traditional one-dimensional modeling lacks the ability to model three-dimensional formations, while the numerical calculation methods for three-dimensional modeling are complex in form, take longer to calculate and require higher computer performance. In order to quickly and accurately calculate the conductivity of complex formations, a two-dimensional formation resistivity logging model that simulates three-dimensional resistivity logging is established.
