| 摘 要： | 本文通过对航磁和重力资料的分析和研究，对民和盆地基底结构及起伏形态、构造特征提出了一些看法，并动用地球物理场特征加经描述。认为永登 凹陷是盆地内最深的凹陷，这一发现将为寻找油气指出方向。同时结合重力资料对侏罗系的厚度和分布范围进行了确定，为以些为目的层的油气勘探提供了参考依据。文中还对盆地的构造发展及盖层的发育特点进行了探讨。

| Abstract: | Based on an analysis of gravimetric and aeromagnetic data, the authors revealed the basic structure,geometry and the corresponding geophysical features of the Minhe basin.Onsuch a basis, it is believed that the Yongdeng depression should be the deepest sag in the basin, and the exploration of oil and gas should be focused there. The thickness of distribution of the Jurassic in the depression were determined and mapped, which serve as important reference data for the coming petroleum exploration of the Jurassic in the region.In addition, the structural history and the characteristics of the sedimentary rocks in the basin are discussed in detail. |
