目的：研究该洼陷形成机制，构造亚带划分及其分布规律。方法：通过构造地质学及区域应力场的研究来分析南－孟洼陷地质构造。结果：划分出3个构造亚带，找出了构造亚带的分布规律，明确了北东向断层的分块作用，据北北东向次级断层断面倾向的变化划分了6个区块。结论：在研究的基础上，指出以王楼、孟岗集为南界的洼陷北部是近期油气勘探的重点地区。
Objective: To study the formation mechanism of this depression, the sub-division of structure and its distribution. Methods: To analyze the geological structure of Nan - Meng slatform through the study of tectonic geology and regional stress field. Results: Three structural sub-belts were divided and the distribution of structural sub-belts was found out. The division of the north-eastern fault was clarified. According to the tendency of the north-north east sub-fault, 6 blocks were divided. Conclusion: On the basis of the research, it is pointed out that the northern part of the depression with Wanglou and Menggang Set as the southern boundary is the key area for recent oil and gas exploration.
