The invention provides a description method of a turbidite reservoir with a high sandstone-stratum ratio. The method comprises steps of step 1, carrying out fine synthetic recording calibration and explicating a corresponding relation between lithological characteristics and seismic reflection characteristics; step 2, carrying out multi-well crossploting analysis and optimally selecting a well measuring curve capable of effectively distinguishing sand shale; step 3, by use of the effective well measuring curve, carrying out reservoir reversion under waveform indication; step 3, based on the well, carrying out mutual comparison and careful analysis on the well participating in the reversion and determining reversion chromatography blocks; and step 5, carrying out comparison verification onreal drilling sand bodies of wells which participate in and fail to participate in the reversion with well side reversion channels, and carrying out accurate tracking description on the sand bodies byusing the reversion and drilling data. According to the invention, sand body shapes matching with the actual depositional characteristics can be accurately and quickly described; and growth and distribution characteristics of the turbidite can be quite precisely reflected.
