摘要
基于边界积分方程 ,提出了依据二极采样数据、但利用电位差的某种线性组合的“准三极”电阻率层析成像方法 .研究表明 ,该方法不仅较好地解决了对高阻异常体的成像问题 ,而且使低阻异常体的成像质量获得了明显改善和提高 ,因此增强了电阻率层析成像技术的实用性 .
Based on Boundary Integral Equation(BIE), the“Quasi three poles” resistivity tomography method is suggested in this paper in which data are got with “pole pole” array but some kind of their linear combinations are used for inversion. The study results show that this method can not only resolve the problem of tomography to resistive bodies, but also improve the quality of tomography to conductive bodies, both under the condition of high contrast of conductivity of background to anomalies, so the method of this paper can improve the practice of resistivity tomography technology.
