Claim 8:
9. The fault characterization method for precise navigation of deep oil and gas based on image fusion as described in claim 1 is characterized in that the center point position of the bead-like structure is obtained by:
based on the superimposed fault attribute map, average coordinates of each point are obtained to obtain a center position (x, y, z) of the bead-like structure:, x
