中文摘要：

惠民凹陷构造复杂，油气勘探程度较低。本文在研究大量地球物理资料和区域地质基础上，分析了新生代构造特征，深化惠民凹陷南斜坡立体构造解释；发现并提出NWW基底剪切带和其伴生构造，初步探讨了其成因机制，认为该区深、浅构造差异性明显。

英文摘要：

The structure of Huimin sag is complete and the degree of exploration is low. Analyzed the structural feature of Neozoic based on researched large number of geophysical data and local geologic data, further interpreted the structures in the southem slope of Huimin, found out and presented the NWW base shear zone and its associated structures, analyzed its generation mechanism. Finally it was thought that the difference between the structures in shallow and deep were very obviuse.
