川西坳陷中段中、新生代构造运动与须家河组生、储、盖层发育关系研究

川西坳陷中段中、新生代的构造运动主要表现为：早印支期的抬升、褶皱，构造雏形形成阶段。晚印支期褶皱、隆起发育，燕山期的挤压改造阶段。喜马拉雅运动对该区影响相对较小，仅形成了一些浅层断裂。研究表明，构造运动控制了坳陷中段的形成和发展，不仅控制了须家河组生储盖的发育，还控制着储层的孔隙度、渗透率变化．渗透率与孔隙度相关性较小，主要与裂缝有关。分析表明储层裂缝发育地带是有利的勘探区域。

The Relationship of Mesozoic and Cenozoic Tectonic Movement to Xujiahe Reservoir Capability in the Middle West Sichuan Depression

Mesozoic and Cenozoic tectonic movement in the middle west Sichuan depression was characterized by uplifting and folding resulting in the tectonic embryonic form in the early Indo-Chinese epoch and folding and uplifting in late Indo-Chinese epoch and compression and reformation in the Yanshanian epoch The study indicates that the Xujiahe reservoir capability is controlled by the mentioned-above tectonic actions.
