Representation method for diagenetic seismic facies of sandstone reservoir

The invention discloses a representation method for diagenetic seismic facies of a sandstone reservoir. According to the representation method for the diagenetic seismic facies of the sandstone reservoir, quantitative indexes of typical rock electric parameters for reflecting the diagenetic characteristic of the sandstone reservoir and the environment are utilized to accurately evaluate the diagenetic facies longitudinal phase sequence of the sandstone reservoir of a non-core hole and the plane distribution and the rule of the diagenetic facies of the target stratum reservoir, more effective technical information is provided for sandstone oil and gas exploration and development, favorable blocks of the sandstone oil and gas exploration and development are optimized, the forecasting accuracy of the favorable blocks is improved, the success rate of exploration and development is improved, and the cost of exploration and development is lowered.
