| 摘 要： | 川东高陡构造位于四川盆地东部 ,由一系列 NE-NNE向的隔档式褶皱组成。其构造变形经历了由隔槽式褶皱到“两背一断”,最终形成隔挡式褶皱的演化过程。在“两背一断”先存构造研究基础上 ,按继承发展的观点 ,综合运用伸展构造、反转构造、断层相关褶皱等构造新理论 ,系统探讨了川东高陡构造形成演化的成因地质模式 ,结合志留系主力生烃层的生气高峰期 ,对地腹不同成因类型的构造圈闭含气性进行了分析。

| Abstract: | The high and steep structures in east Sichuan, located in east Sichuan Basin, are composed of ejective folds. The structural deformation has experienced the evolution from trough like folds to "two anticlines with one fault", and finally formed ejective folds. Based on the studies of pre existing structures of "two anticlines with one fault", according to the viewpoint of inheritance and development, comprehensively using the new structural theories, such as extensional structures, inversion structures, fault related folds etc., the authors systematically studied the genetic geologic model of high and steep structures and analyzed the gas bearing character of different types of subsurface structural trap by combining with the gas generating peak of the Silurian key source bed. |
