Method and device for high density detecting polarizability using metal electrode

Abstract

A device of using metal electrode to detect polarizability is prepared as setting hold circuit and summation circuit of sampling in said device then controlling each step of detecting polarizability by setting operation program of computer.

Description

technical field [0001] The invention belongs to a geophysical detection method and equipment, in particular to a method of polarizability imaging technology and a device used therefor. Background technique [0002] The so-called high-density detection of formation polarizability is to use a high-density electrical imager to connect a detection cable, and set a large number of electrical connection points for connecting electrodes on the line, with 60, 120 or more. All electrodes are connected with electric imager through this cable, see accompanying drawing 2. Under the control of the electric imager, the polarization potential value of the formation is measured by scanning, and then the polarizability is calculated. [0003] When the metal electrode is driven into the soil at a certain point, the positive and negative charges are adsorbed on the electrodes of different polarities. As time goes by, they gradually accumulate and exist on the electrodes in the form of polariz...

It can be seen that the cumbersomeness of this method

Moreover, the non-polarization of the so-called non-polarized electrode means that it does not produce a polarization effect, which is also relative. It actually still has a polarization effect. Although it is much smaller than the metal electrode, it still has a non-negligible effect on the detection results. influences
