Structural characteristics,formation and evolution of Shajingzi fault zone in the northwest margin of Tarim Basin,China
The Shajingzi fault zone in the northwest margin of Tarim Basin lies between the Wensu Uplift of Tabei Rise and the Awati Sag of the northern depression.It is a first-order fault zone in Tarim Basin,which consists of Shajingzi fault,Yingxiong fault,Wensu fault and Shanan fault.The Shajingzi fault is the main fracture,and the other three are its branches.The Wensu branch fault is a new discovery of this study.And we interpreted the Shanan fault as the front back-thrust fault of the Yingxiong fault,which belongs to the Shajingzi fault zone.The Shajingzi fault zone was formed from the end of Ordovician to the beginning of Silurian,and was finally formed after the Late Devonian to Carboniferous,the end Permian to the beginning of Triassic,the end Jurassic to the beginning of Cretaceous,the end Cretaceous to the beginning of Paleogene and the Neogene to Quaternary multicycle thrust.The Shajingzi fault zone is a fault-controlled oil-gas rich zone,which controls the formation and distribution of Wensu oilfield,Tuotan1,Shanan1 and Xinsudi1 oil and gas reservoirs.
