The application provides a sandstone and conglomerate OVT domain partitioned gather optimization stacking offset optimization method, which comprises the following steps: step 1, determining the fan body burial depth H and the fan body plan distribution map of the target layer in a research area; step 2, reasonably optimizing a real drilling well reconstruction time-depth relationship function formula A in the research area; step 3, calculating a fan body dip angle alpha; step 4, determining the maximum effective offset l2 of the reflection flat section of the target layer in the research area; step 5, calculating the minimum effective offset l1 of the target layer fan body in the research area; and step 6, obtaining the optimal gather stacking offset range l of the target layer fan body in the research area by comprehensively combining the step 4 and the step 5. The sandstone and conglomerate OVT domain partitioned gather optimization stacking offset optimization method can calculate the optimal offset range of the OVT domain partitioned gather optimization stacking of the target layer, and the obtained seismic data volume can better reflect the sandstone and conglomerate fan body distribution range and the effective reservoir development area.
