2D 3D Geophysical Exploration Instrument for Underground Water and Metal

Introduction

Underground geophysical exploration instrument can be widely used in the exploration of metal and non-metal mineral resource exploration, urban exploration, and railway bridge exploration. It is also used to find hydrological and engineering geological explorations such as groundwater, determining the base of reservoir dams.

Measure mode: apparent resistivity, natural potential, polarization rate, voltage

Multi-Electrode2D Resistivity Imaging: it can conduct 2D resistivity imaging, take

WDA-1/WDA-1B as the mainframe. And WDZJ-4 is multiplex electrode converter

Intelligent Multi-Electrode 2D Resistivity Imaging: There are two systems that can conduct 2D,3D resistivity and multi-IP imaging, take WDA-1/WDA-1B as the mainframe.with multi-electrode or IP electrode and resistivity cable or intelligent cable.

Working Principle

Along the horizontal plane or the vertical planes of X and Y axis direction, a limited solid space can be divided into numerous short rectangular columns which are combined as the 3D Model of this solid. And in each column, an appropriate point could be regarded as the approximate resistivity of the whole. What is the difference between them is, 2D imaging mode divides one big cross-section into different smaller ones and measures all the survey points of small sections to complete the measurement approximately, while 3D imaging mode is developed from 2D, finishing the measurement approximately through combining all the points along the planes of different directions (in column mode) on the basis of 2D measurement. However, 3D imaging mode is not only a simple combination of 2D mode but involves data processing by inversion software to make the inversion model more practical. Electrode array of 3D imaging is S-shaped rectangula , taking four adjacent electrode locations as the corners of small column on the ground, which means the length and width of column is equal to the unit electrode distance. Then resistivity of these columns at different depths could be measured by different electrode combination modes. Finally, measured data is processed by inversion software, reflecting the underground with model.
