| 摘 要： | 通过对辽河盆地西部凹陷北部地区构造特征研究,将新生代盆地划分为初始裂陷、伸展断陷、挤压拗陷3
个演化阶段。新生代构造以张性断裂为主,兼具走滑和反转特征,其中,沙四、沙三期为伸展断裂系统,沙一、沙
二至东营期为走滑断裂系统,馆陶期为挤压断裂系统。沙箱模拟实验证明,挤压反转构造受断层下盘施力方式
控制,与基底走滑作用有关,伸展断裂控制的断鼻状构造和挤压背斜构造是高升斜坡带和牛心坨隆起带上较为
有利的目标优选类型。

| Abstract: | Cenozoic evolution of northern area in west depression of Liaohe Basin can be divided into initial rifting
stage, extensional faulting stage and compressional depressing stage. Faults with extensional structure, wrench
structure and inversion structure can be divided into extensional fault systems during the Shahejie phase of Early
Eogene, wrench fault systems during the Dongying phase of Late Eogene and inversion fault systems during the
Guantao phase of Early Neogene. Sand box simulation proved that inversion is controlled by the stress relating to
strike-slip movement coming from the footwall. Faulted block structure controlled by extensional structure and
compressional anticlines are favorable areas for oil and gas accumulation in Gaosheng slope belts and Niuxintuo
upwarping. |
