本文采用物理模拟相似准则,推导出在相同地电模型情况下,发射线框边长非100m回线装置的响应与发射边长100 m重叠回线装置的响应之间的转换公式,该方法定名为相似模拟法(PSM).采用该方法对反演效果不好的发射线框边长非100 m回线装置采集的数据进行预处理后再1D反演,结果表明:某些反演模型响应曲线与实测曲线拟合效果较差的数据,经预处理后,反演模型响应曲线与实测曲线拟合较好,反演电阻率更接近真实的地质情况,反演结果的横向分辨率更高.某些不能得到反演结果的非100 m边长装置数据经预处理后能得到比较接近实际地质情况的反演结果.
In this paper, the similarity criterion of physical simulation is used to deduce the conversion formula between the response of non-100m transmission line device with 100m overlap transmission line and the response of the transmission line with 100m overlapped transmission line under the same geoelectric model. The method is named (PSM). Using this method, the data collected from the non-100 m loop line with poor inversion performance are preprocessed and then retrieved by 1D. The results show that some inversion models respond After the pretreatment, the response curve of the inversion model fits well with the measured curve, the inversion resistivity is closer to the real geological conditions, and the horizontal resolution of the inversion result is higher Some non-100 m side-length devices that can not obtain the inversion results can be preprocessed to get the inversion results closer to the actual geology.
