| 摘 要： | 相位激发极化法是一种频率域激发极化方法,可直接测量电场电压与供电电流之间的绝对相位差。由于该方法对仪器精度要求较高,因而国内有关实际应用方面的资料相对较少。在金属矿产勘查中,目前国内大多采用时间域激发极化方法,测量岩矿石的极化率或充电率。虽然频率域激发极化法也有应用,但主要采用双频或多频测量,利用视频散率参数进行解释,野外测量工作量较大,测量精度相对较低。近几年,利用相位激发极化法在科研、生产中做了一些工作,这里介绍相位激发极化法模型试验及数据反演结果,岩矿石标本时间域(充电率)和频率域(相位)测试对比结果,以及实际应用实例及数据反演结果。应用结果表明,用相位激发极化法在矿产勘查中可以取得较好的勘察效果,并能在今后的工作中发挥更大的作用。

| Abstract: | The phase induced polarization(Phase-IP) is a method in frequency domain;It measures absolute phase difference directly between measuring voltage and supplying current.Since the method requires high accuracy apparatus,it is lack of related references of the Phase-IP information at home.At present,the induced polarization method in time domain is adopted mostly to measure the polarization and charge rate of ore deposits.Although the frequency domain IP is applied too,it has much working capacity and the lower survey accuracy because double or more frequencies is adopted and the interpretation is processed through the apparent dispersion rate parameter.In recent years,we have done a lot of work through the phase-IP method in the science study and in the production.The paper introduced the model testing and the data inversion results with the PhaseIP in typical model examination,and the correlation results of the charge rate in time domain contrast to the phase in frequency domain,and also the application cases in miner searching work with the method.The practical applying results explain that the Phase-IP method can be taking a good exploration effect and can be playing great role in mineral exploration. |
