在水平层状介质模型条件下,离散的电阻率函数可用一种褶积滤波形式表示,此滤波系数利用一阶贝塞尔函数求出。用此滤波系数对实际的ρ_S曲线进行滤波,得到各点的转换电阻率实测值T_(io)。根据各层电性层参数计算的转换电阻率理论值T_(io)将T_i与T_i进行比较,若T_ i偏离较大,则需反复修改电性层参数,直至达到精度符合要求为止。这时T_i值的电性层参数便是实测T_i值的精确解。文中列举了H型理论曲线和两个实际例子,证实了方法的应用效果。
In the case of horizontal layered media model, the discrete resistivity function can be expressed in terms of a convolution filter, which is calculated using a first-order Bessel function. The actual ρ_S curve is filtered by this filter coefficient, and the measured value of conversion resistivity T_ (io) at each point is obtained. Calculate the theoretical value of conversion resistivity T_ (io) according to the parameters of electric layers in each layer to compare T_i with T_i. If T_i is greatly deviated, modify the parameters of electric layer repeatedly until the accuracy is met. At this time T_i value of the electric layer parameters is the exact solution of the measured T_i value. The article lists the H-type theoretical curve and two practical examples, confirming the application of the method.
