Born近似快速三维反演井地电法数据

The main goal of this paper is to develop a method of 3D imaging for the field excited by a electrical dipole located in borehole and received at the surface of the earth.Our method is based on the Born Approximation and re-weighted regularized conjugate gradient(RRCG) method.The numerical result demonstrates the Born Approximation can be effectively used for 3D imaging for borehole-ground electrical method.It also demonstrates that the method can be used as the basis for fast 3D inversion in reservoir monitoring application and in water injection exploration.
