摘要
万安盆地构造演化经历了早期裂陷和晚期裂后两大阶段,盆地幕式构造沉降特征明显。构造演化的阶段性和幕式构造沉降控制了盆地沉积物充填,而盆地的构造沉积演化对区内烃源岩、储盖组合及圈闭等成藏要素以及这些要素的时空配置起控制作用。
There are two tectonic evolution stages in Wan'an basin, i.e. the syn-rift stage and post-rift stage, which are markedly characterized by the episodic subsidences. Sediment filling in the basin is controlled by its tectonic evolution periods and episodic subsidences, and this tectonic-sedimentary evolution may in turn have a control on source rocks, reservoir-seal assemblages, traps and their temporal and spatial distribution.
