Abstract:This paper briefly introduces Kirchhoff prestack depth (Q) migration, Gaussian beam prestack depth migration, and one-way wave equation prestack depth (Q) migration of GeoEast-Lightning prestack depth migration software. Then, the application effects of different prestack depth migration methods in the Hutubi 3D seismic area in the southern margin of Junggar Basin are compared and analyzed to provide references for seismic data processing in similar areas. The results are as follows. ①Kirchhoff prestack depth (Q) migration technique is widely employed in practical production, whereas its imaging ability and accuracy for complex structures are limited. ②The Gaussian beam depth migration overcomes the low accuracy of the integral migration method and retains the efficiency and flexibility of the integration method. Compared with wave equation migration, its computational efficiency is greatly improved. ③The one-way wave equation prestack depth (Q) migration method is efficient with less time consumed and is suitable for imaging in most geological conditions with a certain dip angle.
