民和盆地是一个典型的中、新生代改造型沉积盆地,盆地的形成和发展经历了燕山运动期成盆,喜马拉雅运动期改造等多次构造运动,两坳两隆构成了盆地的基本构造格局;盆地主要发育三种类型的生储盖组合。强烈的构造运动导致盆地内形成众多的各类圈闭,通过构造形成和发展规律的综合研究,预测民和盆地发育有六类圈闭,这些圈闭的分布地带是下一步寻找油气的有利勘探方向。

The Minhe basin is a typical reconstituted type depositional one, rebuilt in period of Mesozoic and Cenozoic. The formation and development of the basin experienced many times of tectonic movement including the formation of the basin during Yanshan movement period and rebuilt during Himalayan movement. The basic tectonic configuration is “two-sag and two-uplift”. There are three types of source-reservoir-cap assemblages in the basin. Numerous trap of various types are results of intensive tectonic movements. Through the comprehensive study on the formation of structures and their deveiopment reguiarities, it is predicted there will exist six types of traps. The future promising prospecting area will be situated in distribution area of such traps.
