| 摘 要： | 本文提出了一种新的二维电阻率成像方法,即电阻率层析成像.介绍了电阻率成像的几种供收方式,借鉴地震波和电磁波的反投影技术,应用电阻率反投影并联合使用常规算法,即导电α中心法作正演计算、非线性最小二乘法作反演修改,从而进行二维电阻率的图像重建.用Fortran语言编制了实现上述过程的程序,进行了大量数字模拟实验,获得较好的成像效果.

| Abstract: | This paper presents a new two-dimentional resistiving imaging method, namely resistivity tomcgraphic imaginery, and describes some supplying-receivipg ways for resistivity imagery.It takes advantage of the reverse projection technique of seismic wave and electromagnetic wave, and applies the reverse projection of resistivity combined with the utilization of routine algorithm (conductive center method for direct calculation and nonlinear least squares method for inverse revision)so as to carry out the reconstriction of two-dimensional resistivity image.Using Fortran language,the authors made programming for realizing the above process, and performed lots of digital simulation experiments and, as a result,obtained fairly good imaging effect. |
