The basic principle of high frequency and other parameters induction is introduced. Taking the typical three wells in Shengli Oilfield as an example, the application of high frequency induction data in the detailed analysis of thin intercalations, determination of reservoir fluid saturation type, and evaluation of reservoir resistivity spatial distribution are analyzed in detail. The results show that high-frequency induction has very high vertical resolution and good radial detection characteristics, and can accurately calculate the real formation resistivity, intrusion zone resistivity and invasion radius. By comparing with conventional sensing and thin-layer logging data In contrast, the superiority of high-frequency isoparametric sensing in the application of logging technology is demonstrated
