Tectonic subsidence play dominant role in their geometric shapes, basin fillings, sequence evolution and sediment distribution in the Wushi Sag. Outline of the sequences are in shape of box-wedge or sheet-wedge and boundaries of sequences are varied from bilateral fault to monoclinal fault overlap, so that the sequences show distinct semigrabens which overlay in different ways. Seven sequences were formed in different stage of tectonic evolution. The sequence of SQ1 formed in initial rift stage and deposited alluvial sequence. Sequences SQ2-SQ4 developed in intense rift stage and sediment lacustrine sequence. Sequences SQ5-SQ7 formed in late period of rift before thermal subsidence and deposit mere and delta sediment. The place adjacent to the synsedimentary fault is the subsidence center and depocenter; meanwhile, controlling fracture migrates in horizontal made subsidence and sedimentary center of the sag changed.

Based on the evolutionary history and drilling well data of the subbasin, this paper discusses the mechanism and time of formation of this transverse accommodation zone and proposes that the first-order accommodation zone formed in a stage of strong extension of the subbasin, while the second-order accommodation zone formed in a stage of weak extension of the subbasin.

Seven thirdorder seismic sequences can be recognized from bottom to top in the Paleogene in the Wushi sag, which consist of a depositional sequence from transgression to regression as a whole and correspond to different stages of structural evolution. Sequences developed in different stages of structural evolution are different in filling sequence and distribution of sedimentary system. Multiphase structural evolutions result in development of source rocks and reservoir and cap rocks in various parts of the sag. The sequence 2-4 deposited in strong chasmic stage have the best source rocks and sealing conditions as well as various favorable reservoirs, thus are the most favorable targets for obtaining discoveries in this sag.

During the Cenozoic, the evolution of the sag might be divided into three stages: during the Eocene, because of regional extension effect of the NW-SE-striking, it was a ramp depression controlled by the Cangdong fault; during the Oligocene, it might have subjected to the combined effects of the NW-SE-striking regional extension and the dextral slipping of the NNE-striking deep fracture zone; during the Neocene and the Quaternary, though the regional extension had mainly stopped, the dextral slipping continued. Inside the slip zone, the local, SN-striking extension related to the dextral slipping became more and more apparent.

The general feature of deformation caused by the collision between two continents also reveals that, during the collision process, apart from a foreland basin and high mountains being formed, there is another compressive depression with an asymmetric structure developed on the side of the obducted plate, which is much easier to be formed when the dip angle of the collisional fracture zone is between 15° and 30° and is the deepest with a dip angle of 30°. This implies that the compressive depression is controlled by both subduction and obduction between two continents.
