Abstract:As the exploration maturity is getting higher and higher,lithologic reservoirs have become the important exploration targets in Fushan Sag.Poststack inversion and hydrocarbon detection provided by GeoEast interpretation sub-system offer a powerful technological support for lithologic reservoir prediction in Fushan Sag.With poststack inversion,favorable accumulation patterns for lithologic reservoirs are figured out: slope fan reservoir of flexure-slope break low-system tract (LST).Depending on hydrocarbon detection,we find out seismic frequency spectrum in FS_Y area with the characteristics of “low-frequency resonance and high-frequency attenuation”,which provides reference for sand-updip pinch-out lithologic reservoir exploration.
