摘要
激发极化法(Induced polarization method, IP),简称激电法,是以岩、矿石的激发极化效应为基础,通过建立人工激电场,观测和研究岩、矿石受激发产生的极化场,来达到勘探目的的一类地球物理勘探分支方法。其可以分为时间域激电法和频率域激电法。自上个世纪50年代激发极化法传入我国开始,激发极化法在我国得到了快速的发展。目前激发极化法已经广泛应用于国民生产中的各个方面。中间梯度装置与偶极-偶极装置是激发极化法比较常用的两种装置,其装置自身拥有各自的优点及缺点,但作为有源场其勘探结果会受到电极影响。
     随着计算机的发展,数值模拟已经成为目前国内外对于地球物理研究的主要模拟手段,而实验模拟已经较少被使用。但实验模拟手段因其相比于数值模拟更接近于实际情况,模拟的效果更具有指导意义。因此将两种模拟手段结合在一起是必要的。
     本文主要采用对激发极化法中常用的中间梯度装置和偶极装置进行详细的物理实验模拟和数值模拟的手段,得到完善的视电阻率和视极化率曲线,进行针对性的比分析的手段,对极化体的激发极化性进行研究。本文取得如下成果:
     1、对中间梯度装置及偶极装置进行系统的物理实验模拟和数值模拟,得到一套完整的不同模型的异常曲线,并分析其产生异常的原因及规律。
     2、中梯装置及偶极装置的适用条件不同,对于同性质的模型,其效果不同。此外二者的供电电极对于勘探的数据会造成一定的影响。给数据的分析、解释带来一定的困难。因此需要对其异常形态有足够的了解才能准确的分析和解释。
     3、本文系统的研究了不同情况下的激发极化特性,其研究成果对于激发极化法的理论研究及生产实践具有较强的指导作用。
     4、指出了目前激发极化法的一些不足之处并对于今后的工作提出了一些建议。
Induced polarization method (IP) is based on rock, ore, metal induced polarization effects to find and solve hydro-geological, engineering geological issues, such as a group of electrical prospecting methods. It consists of time domain method and frequency-domain method. Since 1950s, induced polarization method has been rapidly developed in our Country. At present, the IP method has been applied in various areas. Central gradient array and dipole-dipole array are the common configurations of IP method and they have their own advantage and shortcoming. Since the deployment of the source field, the exploration results of IP method also are affected by their electrodes.
     With the development of computer technology, numerical simulation has become the main means of geophysical simulation, and the experimental simulation has been less used. However, the results of experimental simulation fit the actual situation much better than numerical simulation, and experimental simulation is more meaningful in practice. Therefore, it is necessary to combine them into the simulation.
     By comparison, the results and conclusions are as following:
     1、By comparison, we can find that the numerical simulation has a good performance in simulating the induced polarization effect of models, in most cases, but for some situations, compared with the experimental simulation, there are some differences exist.
     2、The applicable abilities of central gradient array and dipole-dipole array are different, for the connatural model, the results sometimes are different too. Furthermore, electrodes of them can cause some effects on the exploration data and bring difficulty in analysis and interpretation.
     3、A Systematic study of the characteristics of induced polarization in difference cases has been done. The result of the study provides suggestions on the theoretical research and fieldwork, based on Induced polarization method.
     4、This paper points out some deficiencies and proposes some suggestions for future research of Present IP method.
