Research and application of two-dimensional high density resistivity tomography

  • 摘要: 电阻率层析成像是基于研究区域边界处的电压和电流值确定区域内部电阻率的分布,它同声波和电磁波层析成像原理有着本质的不同。讨论了电阻率层析成像正演最常用的有限元法,给出了电阻率层析成像反演法的模拟退火方法,并将其成功运用到电阻率成像反演中。应用实例显示,高密度电阻率二维层析成像的分辨率比常规电阻率法解释结果要高,应用前景广泛。
    Abstract: Resistivity tomography(RT) is a technique determining the resistivity distribution within the studied area based on the measurements of potential and current values on the boundaries.It is essentially different from the acoustic and electromagnetic tomography.In this paper,at first,the finite element used most commonly in RT is discussed and the simulated annealing of RT inversion method,and then we discussed simulated annealing algo-rithm and its application to resistivity interpretation.The simulated annealing method is applied to 2-D resistivity inversion.The instance of resistivity tomography is given.It is indicated that the resolution of resistivity tomogra-phy is higher than that of traditional method.
