摘要
The discoveries of reef-shoal reservoirs in the regions of Puguang and Longgang in recent years have shown a promising exploration future in the Kaijiang-Liangping trough area.Using prestack migration seismic data combined with drilling and logging information,identifications of bioherm in the Changxing formation and oolitic reservoir of the Feixianguan formation in western Longgang region have been successfully achieved by a series of technologies such as horizon-flattening,volume-curvature,sequence stratigraphy,and prestack inversion.An assorted preliminary workflow for reef-shoal body identification is developed and may contribute an important reference for similar areas.
