Abstract: There exist obvious differences of the event shapes between diffracted wave and reflected wave in dip angle gather, that is, the reflection event appears as a concave curve while diffracted wave as quasi-linear event. In view of this, a new diffraction separation and imaging method based on reflection prediction is proposed in dip angle domain, by which the diffraction imaging on Sigsbee2a model was conducted. The results show that using this method can effectively suppress the specular reflection, improve the resolution of diffraction imaging, and enhance the identification accuracy of diffraction targets. It is proven by applying it to a complex reservoir sands model in a prospecting area that this method is of better adatability
