Cole-Cole模型是频谱激电的一个重要模型,其参数可以区分引起激电异常的极化体和寻找深部矿(化)体。目前时间域激发极化法通常只利用视电阻率和视极化率(或某一个视充电率)数据对勘探目标进行解释,而忽视了其它视充电率数据,造成资源浪费。为充分利用时间域激电数据,提出一种Cole-Cole模型参数反演方法。该方法只需要3个以上视充电率,简单易行,不会明显增加野外的工作量,为时域激电勘探提供更为丰富的信息。算例表明,这种方法反演精度较高,结果可靠。同时,本文在不同的仪器之间分别采集了时域和频率域的激电实验数据,通过对时域和频率域Cole-Cole模型频谱参数反演的对比计算,验证了该方法的可靠性。
The Cole-Cole model is an important model of the spectral power spectrum with parameters that distinguish between polarizers that cause the anomalies of the anomalies and the search for deep ore bodies. In the current time domain, the excitation polarization method generally uses only the apparent resistivity and the apparent polarization rate (or a certain apparent charge rate) data to explain the exploration target, ignoring other apparent charge rate data and resulting in waste of resources. In order to make full use of time-domain data, a Cole-Cole model parameter inversion method is proposed. The method requires only three or more apparent charge rates, which is simple and easy to operate, does not significantly increase the workload in the field, and provides more abundant information for time-domain power exploration. The example shows that this method has high accuracy and reliable results. At the same time, the experimental data collected in different time domain and frequency domain are collected in different instruments, and the comparison of the spectral parameters of Cole-Cole model in time and frequency domain is carried out to verify the reliability of the method.
