AI Technical Summary

Technical Problem

Existing magnetic anomaly polarization techniques do not fully utilize aeromagnetic three-component data, resulting in low data utilization and difficulty in accurately determining the magnetization state of complex geological bodies. Furthermore, traditional methods have poor stability in low-latitude regions, low inversion efficiency, and are susceptible to noise interference.

Method used

A pole-setting method based on the three aeromagnetic components is adopted. By acquiring and processing northward, eastward and vertical data, and using an improved Transformer model for inversion, equivalent rectangular data is constructed to achieve stable pole-setting across all latitudes.

Benefits of technology

It significantly improves data utilization and anomaly interpretation accuracy, corrects the influence of remanence, enhances the stability and inversion efficiency of polarization results, and is suitable for large-scale massive data processing.
