Analysis of Shielding Characteristics of MIT7530 Array Sensing Instrument Based on Digital Twin

Induction logging instrument is a kind of electrical instrument that is now used more frequently, and analyzing the influence of shielded coil on the receiving voltage is the premise to ensure that the voltage value is correct. This paper is based on the array induction instrument MIT7530 and starts from the basic principle of induction instrument logging. Visual Studio software is used to design a shielding characteristic analysis program, and the output data is read and written in the format of JSON files. The characteristics of the imaginary and real parts of the voltage values of the seven arrays at three frequencies were analyzed, and their characteristics changed with the number of turns and source distance of the shielded coil.
