Abstract

Abstract:

The study of fault development characteristics of the Funing Formation in Gaoyou Sag is of great significance to the understanding of the sag evolution and oil-gas enrichment.There are a large number of domino-type faults dipping NW in the east of the sag, and Ⅴ-shaped faults dipping NW and SE in the west of the sag.The difference in fault development characteristics indicates different fault formation processes, and the fault formation mechanisms in different zones are yet to clarified.Through three-dimensional seismic interpretation, unconformity and residual stratum identification, combined with displacement-depth curve and structural evolution analyses, it is proven that the boundary faults in the Funing Formation of Gaoyou Sag are non-syndepositional, thus having no obvious control on the formation of secondary faults in the sag.All faults of different assemblages in the east and west of the sag are formed under uniform stress field striking NW-SE, with main activities occurring at the end of the Funing Formation deposition.Two sets of physical simulation experiments were therefore designed according to the analytic conclusion of faults and the principle of similarity.The experimental results show that the Ⅴ-shaped fault assemblage in the west is formed under bilateral extension, while the domino fault assemblage in the east is controlled by unilateral extension and has no link to the eastern slope.The results of the two sets of experiments can reasonably explain the causes of the differential fault assemblage patterns.Geographically, before the deposition of Dainan Formation, Gaoyou Sag was in the same sag with Linze Sag in the north of the basin that is characterized by a narrow west and wide east.During the extensional deformation period, the stress propagation velocity on both sides of the basin to the center was different, leading to the differential overlapping zones with faults striking to various directions in different areas.
