Abstract: The drilling, seismic and non-seismic data indicate that the southeastern Tarim basin, located at the southeast of Che'erchen fault, has experienced several times of ascending since the end of Early Paleozoic.The structural deformation and deposition in this area at that time were controlled by Che'erchen fault and controlled by the Altun fault belt since Pliocene. Therefore, the southeastern Tarim basin is classified as a first-order tectonic unit of Tarim basin, called southeast uplift. The uplift is characterized by "sections in east-west direction and belts in south-north direction". According to the distribution of strata, structural deformation and the depth of basement, the southeast uplift can be divided into four second-order tectonic units from west to east such as Mingfeng sag, Qiemo swell, Washixia sag and Luobuzhuang swell.

Key words: Tarim basin, south-east structure, sag, swell
