Abstract: It is considered that the Chepaizi Uplift and the beltlike denudation area from Luliang to Mosuowan should be excluded from Chepaizi- Mosuowan Uplift. The main body of Chepaize-Mosuowan Paleo-uplift is situated in sags and slope area. Structural diagrams of uplift can not be drawn out only based on seismic data so far. All data used for proving the shape of anticline structure are all acquired from the profile west of Maqiao salient. They are the same as the structural characteristics of Maqiao salient while they are different from that of Chepaize-Mosuowan Paleo-uplift. So they can not be used as the representative of the Paleo-uplift. It is inaccurate to conduct research on Paleo-structure on the basis of compressed seismic profiles that have not been used for time-depth conversion. Paleo-erosion area has nothing to do with the structure-uplift effect, because batholithite rock beds with large area of gentle slope are denuded by arc shaped erosion base level next to the edge of interior basins. Denudation area does not reflect uplift structure and cannot determine oil and gas distribution. Oil and gas can only be captured in the updip pinch-out part of the closed discordance formation in denudation area, which has broad prospect.

Key words: query, Junggar Basin, Chepaizi-Mosuowan Paleo-uplift, structural uplift shape, oil control effect
