The invention discloses a wheeler domain section sand body carving method based on a three-dimensional earthquake.The method comprises the following steps of determining a sequence top-bottom interface in combination with well shaking, calculating a seismic event inclination angle guiding body, tracking chronological strata according to the result whether inclination angle guiding mutates or not, and arranging chronological strata according to the sedimentation sequence to representing relative geological time, wherein parameters for tracking the chronological strata are of data drive, all the strata are continuous, and the maximum iteration is twice; breaking mutational sites, conducting iteration ten times, and establishing a three dimensional chronological stratum layer body; leveling all single layers of the layer body, and converting all the single layers into a Wheeler domain.Through Wheeler domain sections, the horizontal distribution scope of a sand body can be reflected, space carving is conducted on the sand body, through Wheeler domain seismic sections, horizontal distribution of the seismic attribute inside the sand body can be further reflected, and distribution characteristics of the sand body are researched.By means of the method, accuracy for identifying an alluvial fan sand body ad a fan-delta sand body can be improved, and the well drilling success rate is raised.
