An instrument for measuring resistivity of rock and ore in boreholes. To measure resistivity, a certain amount of electric current is applied to the rock layer, and the potential difference caused by the electric current is measured at different positions of the rock layer, and then the apparent resistivity is calculated. Therefore, resistivity logging instrument generally includes two parts: power supply and measurement record. Due to the influence of the actual measured conditions, the resistivity of the measured result is somewhat different from that of the actual rock layer, so the measured result is called the apparent resistivity. Many methods of measuring apparent resistivity have been developed for different geological purposes. In these different measurement methods, some power supply electrode and measurement electrode structure and combination mode is different, some power supply and measurement form is different. In order to distinguish these different methods of apparent resistivity measurement, many names for measuring apparent resistivity have been given. For example: gradient resistivity, potential resistivity, three lateral resistivity, resistivity logging instrument is simple to use, use is very wide, almost all industries (metal and non-metal, coal, oil field, nuclear industry, hydrology, geothermal, etc.) drilling will be resistivity logging. Resistivity logging data are often used to divide formation electrical profile, calculate porosity, permeability, etc.
