摘要： 卡塔克隆起经历多期构造运动,发育了中奥陶统底面（$T^{4}_{7}$）、志留系底面（$T^{0}_{7}$）和上泥盆统底面（$T^{0}_{6}$）3 个重要不整合面。不整合面类型的组合样式、分布特征和剥蚀趋势的变化控制着该区的油气分布。油气沿着不整合带界面由低处向高处进行大规模和长距离的运移,遇上断裂时则沿着断裂向上运移,并且叠置程度越大,油气聚集的程度就越高。

Abstract: The Katake uplift in Tarim basin has undergone multistage tectonic movements. Three basal unconformities of the Middle Ordovician ($T^{4}_{7}$), the Silurian ($T^{0}_{7}$) and the Upper Devonian ($T^{0}_{6}$) occur in the Paleozoic. The oil-gas distributions in them are controlled by changes of combination configuration, distribution characteristics and denudation tendency. Large scale and long distance hydrocarbon migration appears from low part to high part along these unconformities or along faults when meeting them. The intensity of hydrocarbon accumulation increases with the overriding degree of the unconformities.

Key words: Tarim basin, Katake uplift, Paleozoic, unconformity, hydrocarbon accumulation, evolution
