【Abstract】 Numerical algorithm of three-dimensional electromagnetic modeling using integral equation is realized based on the electrical tensor Green’s function when the apparent resistivity varies linearly in both the horizontal and vertical directions. The effects of the dimension of the anomaly strike on the scattering fields are studied. Three-Dimensional electromagnetic sounding profiles are analyzed. We have also considered the effect of formation parameters on magnetotelluric response, and obtained some important results.更多还原
