It is an instrument for measuring the resistivity of rocks and ores in boreholes. When measuring resistivity, a certain current is supplied to the rock formation, and the potential difference between different locations of the rock formation due to the supplied current is measured, and then the apparent resistivity is calculated. Therefore, the resistivity logger generally consists of two parts: power supply and measurement record. Due to the actual measurement conditions, there are some differences between the measured results and the resistivity of the actual rock formation, and people call such measurements the apparent resistivity. Many different methods of measuring apparent resistivity have been developed for different geological purposes. In these different measurement methods, there are different structures and combinations of power supply electrodes and measurement electrodes, and there are different forms of power supply and measurement. In order to distinguish these different methods of measuring apparent resistivity, many different names for measuring apparent resistivity have been named.
Gradient resistivity, Potential resistivity, Triple lateral resistivity, Double lateral resistivity, Microelectric gradient resistivity, Micropotential resistivity, Microfocus resistivity, Spherical focus resistivity, Single point resistivity, Ground resistivity, Mud resistivity, etc. Resistivity logs are simple to use and very versatile, and are performed for drilling wells in almost all industries (metal and non-metal, coalfield, oilfield, nuclear industry, hydrology, geothermal, etc.). Resistivity logging information is commonly used to delineate the electrical profile of a formation, calculate porosity, permeability, etc.
