Dual Induction - Octal Lateral Logging is an indispensable item in oil and gas exploration in oil fields. However, the linearity of the instrument is not good in the high resistivity layer. In order to improve the logging success rate of the induction instrument and the accuracy of the data measured in the high resistivity layer, According to the principle of induction logging and the need of production, the resistance value of increasing 50Ω · m scale point is theoretically demonstrated and calculated, and the original scale ring is improved. Compared with the well logging data before and after the improvement, Scale ring improved to improve the success rate of logging and the accuracy of the measured data
