摘　　要：塔里木盆地西北缘的沙井子断裂带,位于塔北隆起的温宿凸起和北部坳陷的阿瓦提凹陷之间。它是塔里木盆地的一条一级断裂带,由沙井子断裂、英雄断裂、温宿断裂和沙南断裂组成。其中沙井子断裂是主干断裂,其它3条是其分支断裂。本轮研究新发现温宿分支断裂,并将沙南断裂解释为英雄断裂前缘的反冲断层,归属沙井子断裂带。沙井子断裂带的雏形形成于奥陶纪末—志留纪初,在泥盆纪末—石炭纪、二叠纪末—三叠纪初、侏罗纪末—白垩纪初、白垩纪末—古近纪初和新近纪—第四纪发生过多期冲断作用和新近纪末—第四纪初的张扭性构造变形后,才最终定型。沙井子断裂带是一条断控油气富集区带,温宿油田、托探1油藏、沙南1油藏、新苏地1油气藏等都受其控制。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.
