摘　　要：贝尔凹陷位于海拉尔盆地南部,蕴含丰富的油气资源,受到石油地质学家的广泛关注。由于凹陷白垩纪受多期构造运动的影响,构造演化过程复杂。本文通过地震资料解释与平衡剖面恢复来重现区凹陷演化和断裂的发育史,通过上述研究发现,认为贝尔凹陷经历了早白垩世断陷期、早白垩世末断-坳转换期、晚白垩世坳陷期,分别存在三套断裂系统,伸展断裂系统、张扭断裂系统以及反转断裂系统。Beier depression is a secondary tectonic units in the southern part of Hailar basin,and contain vast reserves of oil and gas. Strongly influenced by multi period tectonic movements,the tectonic evolution of Beier depression is very complicated.Based on the seismic profile analysis and balanced cross-section recovery we identified three fault systems which conclude early extensional fault system,middle tensional- shear system and late inverse fault system, Beier depression experienced early Cretaceous faulted period、fault-depressed diversionary period and late Cretaceous depression period.
