Abstract: Based on the geological characteristics and the seismic wave propagation characteristics of the collapse column, a collapse column model is constructed. Considering the change of single factor variation and the acoustic equation used to simulate the effect of different receptor interval and shot interval on the collapse column. Interpretation of the collapsed column fracture boundary is carried out by using the reflected wave amplitude changes of the offset profile and combined with seismic attribute analysis and manual interpretation. The detection accuracy is judged by the average deviation of the horizontal resolution of the collapsed column as an index. And the interpretation error of the diameter of the collapsed column is analyzed by ray tracing method. The results show, that the small receptor spacing is beneficial to the exploration of the collapse column, and when the receptor interval is 5 meters and the shot interval is 40 meters, it is favorable to the exploration of the collapse column model.
