| 摘 要： | 通过对大型走滑型M盆地的研究发现，在早、晚白垩世不同的走滑时期分别形成NEE，NW和NNW向三大构造体系，表现出剪切和扭张两种不同形式的走滑构造特征。认为：M盆地油气丰富但复杂多变，早期，紧临中非断裂带，断陷深度大，沉积下巨厚的下白垩统生油层系；后期，中非断裂带走滑方向变化，沉积中心向南转移，在远离中非断裂带的南区沉积了上白垩统优质的厚层泥岩，形成了大油田的区域盖层，是控制油气分布与富集的关键。

| Abstract: | By studying the large-scale strike-slip basin-M basin, NEE, NW and NNW tectonic systems are found;they formed in different Early and Late Cretaceous strike-slip stages, which shows the characteristics of shear and torsion. M basin has abundant oil and gas with complication and variation, which in early stage close to the Middle African faulted belt had great faulted depth and giant Lower Cretaceous oil source bed; in late stage, with strike-slip direction changes of Middle African faulted belt, sedimental centre moved southwardly, good thick Upper Cretaceous mudstone deposited in south area far from the Middle African faulted belt, and formed regional caprock of giant oil field which controls the distribution and accumulation of oil and gas. |
