【摘要】 济阳坳陷是中国东部一个重要的含油气盆地,在不同时代具有不同的构造特征,其构造演化经历了古生代挤 压变形阶段、中生代的断陷阶段和新生代的断裂拉张构造运动三个演化阶段。在构造期次和构造层的划分上,综 合不同学者的观点并结合地震及不整合面资料提出了自己的观点,把构造期次划为五个阶段,构造层分为五部分, 使济阳坳陷构造幕和构造层的划分更加精细,也更有利于指导油气勘探开发。更多还原

【Abstract】 Jiyang depression is an important petroliferous basin in the east of China. Different structural attitude appears in different ages. Tectonic evolution in Jiyang depression has gone through three evolutional stages of com-pressional deformation in Palaeozoic era, fault depression in Mesozoic era, and tectonic movement of fracture extension in Cenozoic era. Synthesizing various viewpoints of scholars and combining with seismic and unconformable surface informations, writer’s viewpoint was proposed on the classification of tectonic episodes and tectono-stratigraphy. Tectonic episodes were divided into five stages. Tectonic zones were divided into five parts. It makes the classification of tectonic episodes and tectonic zones more careful, which is more favorable to guiding the oil-gas exploration and production.更多还原
