Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] see figure 1 , a natural electric field electrokinetic observation system, including a grid layout system and an electrokinetic observation device, the grid layout system includes a reference electrode 2 and more than two non-polarized electrodes 1, and the two or more non-polarized electrodes Polarized electrodes 1 are arranged on each survey point respectively. More than two non-polarized electrodes 1 can be arranged in the shape of a cross, a square, a well, or a grid, and other shapes can also be arranged according to local conditions; however, the measuring points should be dispersed to cover the exploration area as a whole to obtain the full surface area. Information, to avoid local over-density. The reference electrode 2 is a non-polarized electrode with zero potential reference. The reference electrode 2 is preferabl...

Description

technical field [0001] The invention relates to an observation system, in particular to a natural electric field electrokinetic observation system. Background technique [0002] The natural electric field method is a high-efficiency, low-cost traditional electrical exploration method, which has been successfully applied in metal exploration, oil and gas reservoir exploration, geothermal resource development, hydrogeological exploration and other fields. In recent years, the research on the natural electric field has mainly focused on its dynamics, that is, the electrokinetic effect of the natural electric field; the research has mainly focused on the monitoring of heavy metal pollution, landslides, dam leakage monitoring, volcanic activity, and earthquake prediction. [0003] At present, the observation of the electrokinetic effect of the natural electric field mainly uses a pair of measuring electrodes for measurement and manual recording; however, this measurement method ...
