摘要：

塔里木盆地中央隆起区由西向东呈斜列式排列着巴楚隆起、卡塔克隆起和古城墟隆起。其构造演化过程中既存在统一性,又存在较大的差异性。卡塔克隆起形成及定型时期早,后期改造及调整较弱,具有稳定古隆起的特征;巴楚隆起发育和定型时期晚,至今依然在活动,具有活动古隆起的特点;古城墟隆起具有演化时间长、定型时间较晚的特征。中央隆起区构造变形纵向具分层性,横向具分区性。卡塔克隆起及围斜区和巴楚-麦盖提地区多旋回演化历史形成油气多期成藏、破坏、保存、调整的动态关系,油气藏纵向叠置、横向成排成带分布,构成典型的复式油气聚集带,在中央隆起区及邻区存在一个自西向东呈平卧“S”形的油气聚集带,形成八大目标或者目标群。

Abstract:

Three uplifts(i.e.,Bachu,Katak and Guchengxu)in central Tarim basin show an echelon pattern in distribution from west to east.Their tectonic evolution features in both unity and great differences.The Katak uplift is a typical stable paleo-uplift formed and finalized during the early geological time and slightly reformed and adjusted during the later stage;the Bachu uplift is an active paleo-uplift characterized by late development and formation and is still active at present,and the Guchengxu uplift had undergone a relatively long period of evolution and ceased to change at a late geological time.The structural deformation in the central uplift area features in vertical layering and lateral zonality. The polycyclic tectonic evolution in the Katak uplift and its surrounding slope zone and Bachu-MaiGanTi areas is most likely a process responsible for the complex dynamic relationship among the multiple reservoiring,destruction,preservation,and adjustment.A typical complex hydrocarbon accumulation zone is formed with reservoirs superimposed vertically and lined laterally.Eight hydrocarbon exploration targets or target groups are nailed down in the oil and gas accumulation zone with a flat incumbent "S" shape in the central uplift area and its surrounding areas.

Key words: Bachu uplift, Katak uplift, Guchengxu uplift, polycyclic tectonic evolution, complex hydrocarbon accumulation zone, hydrocarbon exploration target, central uplift area in Tarim basin
