摘要
根据辽河盆地西部凹陷断块运动的特点，提出了断块运动的三种变化模式，认为不同类型的断块姿态控制了不同类型构造带的发育。西部凹陷的复式构造带由东向西可分为断阶带、深陷带、翘倾断块带及斜坡带，其中，翘倾断块带是潜山油气藏形成的最有利构造带。潜山类型以断块山为主，但也存在断块-古地貌型复合潜山。潜山的形成明显受控于断裂活动及断块运动。不同类型的断块带控制了潜山油气藏的分布。
According to the characteristics of fault block movement in Wesern Depression of Liaohe Basin,this article points out three changing models,and thinks that the different fault-block posture control the growth of structuraI zone. The complex structures in Western Depression can be divided from east to west into faultd terrace zone,deep subsidance zone,upwarping faulted block zone and slope zone. Among them,the upwarping faulted block zone is the most advantageous structural zone to the formation of buried hill oil and gas pool. The main buried hill is faulted one and has faulted-palaeo-geomorphologic complex hill too. The formation of buried hill is controlled by faulted activity and faulted block movement obviously. The different types of faulted block zone contro1 the distribution of buried hill oil and gas pool.
