摘要
川东大池干井高陡构造是在先期断层基础上发展起来的台阶状道断层控制的断展褶皱和断层转折褶皱。大池干井构造带的形成不仅在石炭系内形成了众多的裂缝,而且使背斜核部的孔隙度增高。
Dachigan structural zone is one of the steep structural zones in the eastern Sichuan Basin. It is composed of fault-propagation folds and fault-bend folds controlled by stepping reverse faults formed by the inversion of previous normal faults. The formation of Dachigan steep structural zone not only generates many fissures in Upper Carboniferous, but also makes the porosity of Upper Carboniferous higher in the core of these anticlines.
