FMI electrical imaging logging crack width calculation method based on model well

The invention relates to the technical field of fractured reservoir research, and discloses a model well-based FMI electrical imaging logging fracture width calculation method, which comprises the following steps of: obtaining the fracture width of a model well through a fracture width gauge; preparing the slurry in the model well into slurry with different resistivity in batches to obtain slurry resistivity data and corresponding FMI electrical imaging logging crack width; according to the slurry resistivity data of different times and the corresponding FMI electrical imaging logging crack width, different times of stratum contrast ratios are obtained; obtaining a crack width correction coefficient of any well according to the crack width obtained by the crack width gauge, the FMI electrical imaging logging crack width and the stratum contrast; according to the crack width correction coefficient of any well, the corrected FMI electrical imaging logging crack width of the actual well is obtained.
