摘　　要：为了搞清大庆长垣的发育过程,根据断层走向的统计结果和三维地震相干数据体的分析,从大庆长垣的构造特征、变形序列及应力分布出发,论述了大庆长垣的变形序列及形成机制。研究认为:北东向的局部构造、近南北向的大庆长垣、北东向的逆断层和北西向的正断层,均为白垩纪末期北西一南东向挤压应力作用下形成;不同形态、不同性质、不同等级、不同序列及不同方向的具有成生关系的各结构要素在空间和时间上有规律地按一定序列排列组合在一起,共同构成了大庆长垣构造体系;大庆长垣构造体系经历了北东向局部构造发育、近南北向大庆长垣统一、北东向逆断层发育和北西向正断层发育的过程,整体来看具有递进变形的特征。In order to make clear of the development process of Daqing Placanticline, according to the analyses of the statistical results of the fault strikes and 3D seismic coherent data, and from the viewpoints of the structural characteristics, deformation sequence and stress distribution, the mechanism of the sequence formation is discussed. The studies show that NE local structures, near SN Daqing Placanticline, NE reverse faults and NW normal faults are formed under the NW-SE squeeze stress in the end of Craterous system; Daqing Placanticline is comprehensively composed of each structural factors with different morphological species, properties, grades, sequences and genetic relationships in various directions, which are regularly arranged and combined together in a certain sequences in space and time; the system has experienced the following developed structural processes： NE local structures, near SN united Daqing Placanticline, NE reverse faults and NW normal faults. In a whole, the characteristics of progressive deformation are shown obviously.
