伸展断陷盆地的演化特征——以海拉尔盆地贝尔凹陷为例
|
摘要
贝尔凹陷是海拉尔盆地中一个早白垩世的伸展断陷, 通过综合应用地震、钻井等资料对贝尔凹陷的形成及演化进行深入分析, 认为伸展作用和缩短作用的交替进行贯穿了凹陷的演化过程, 白垩纪发育的3个伸展作用幕和3个缩短作用幕控制了凹陷的3期沉积旋回、伸展构造与反转构造的叠加和油藏的形成。伸展作用和缩短作用控制着贝尔凹陷内的构造样式和沉积样式的形成与演化。从而影响着烃源岩、储集层的发育与分布, 并制约着油气的运移、聚集和保存。
The Beier depression in the Hailaer basin is an extensional faulted depression of the Early Cretaceous epoch Based on seismic data and well logs, the evolution of Beier depression is discussed in this paper It is concluded that alternation of extension and shortening is occurred through the evolution of this depression Development of three sedimentary cycles,superimposition of extensional and inversion structures, and formation of oil reservoirs were controlled by three activities of tension and compression in the Early Cretaceous epoch In general, the processes of extension and shortening control the structural styles and sedimentary cycles, and also are responsible for the distribution of source reservoir cap rock assemblages, and the migration, accumulation and preservation of oil and gas
