  • Three-dimensional unwrapping processing method and system for borehole transient electromagnetic method
    Patent number: 12663557
    Abstract: A three-dimensional unwrapping processing method for a borehole transient electromagnetic method includes: acquiring measurement information of each measuring point in a target borehole, where the measurement information includes a secondary field induced electromotive force and a roll angle; establishing, for each measuring point, an unwrapped diagram with the roll angle as a horizontal coordinate and the secondary field induced electromotive force as a longitudinal coordinate; and transforming, when an electromotive force signal in the unwrapped diagram is a negative response, the electromotive force signal into a positive response according to a transformation equation of the roll angle to acquire measurement transformation information. The processing problem of the borehole transient electromagnetic method in detecting a negative induced electromotive force response is solved, and the acquired measurement transformation information includes a negative electromotive force signal.
