description The invention provides an ant body attribute dip angle correction method based on seismic event zero-phase discrimination. The ant body attribute dip angle correction method comprises the steps of performing fault protection-based frequency division diffusion filtering processing on post-stack seismic data; gradient feature attribute calculation is carried out; carrying out inclination angle attribute calculation; gradient replacement is carried out according to different conditions; judging the event zero phase, and identifying the event zero phase of the stable stratum under different stratum conditions; according to the judgment result of the zero phase of the event, correcting the attribute value of the ant body according to conditions; filtering processing and line refinement processing are carried out to improve the continuity and resolution of ant body attributes; and based on the ant body attributes obtained in the above steps, carrying out seismic recognition on a low-sequence fault under the conditi
