Compensation sound wave correction method for fracture development section based on electrical imaging porosity spectrum

The invention discloses an electrical imaging porosity spectrum-based compensation sound wave correction method for a fracture development section, which comprises the following steps of: firstly, determining a compensation sound wave correction curve based on a plurality of logging curves, then carrying out porosity spectrum characteristic analysis based on electrical imaging logging information, and extracting a porosity spectrum mean value to reflect the carbonate rock fracture development degree; and finally, correcting the compensation acoustic logging curve of the fracture development section based on the average value of the electrical imaging porosity spectrum in combination with the calculated compensation acoustic correction curve. According to the scheme, conventional and electric imaging logging information is fully combined, compensation sound wave calculation is carried out by using methods such as optimization, the determined compensation sound wave curve can well reflect longitudinal wave spee
