摘　　要：依据三维地震等资料,深入研究霸县凹陷东营组三段断坳转换期发育的断层,识别断层发育样式,总结由断层控制形成的古地貌特征,结合岩心、单井、地化等资料,进一步分析断层控制发育的古地貌对沉积相和砂体的空间分布的控制作用,总结控制模式。研究表明,东三段沉积期主要发育3种控砂模式:帚状同沉积断层控砂模式,雁列式断裂组合控砂模式和平行同向断层转换带控砂模式。The faults developing in the third member of Dongying Formation in the fault-depression transition period of Baxian Sag are studied based on the previous research and 3D seismic data,the development patterns of the faults are recognized,and the characteristics of the ancient landform controlled by the faults are summarized. The control effects of the ancient landform controlled by the faults on sedimentary facies and the spatial distribution of sandbodies are further analyzed according to core,logging and geochemical data,and the control patterns are summarized. The study results indicates that there are three sand-body control patterns in the third member of Dongying Formation: the broom-shaped syndepositional fault sand-body control pattern,the wild-goose-formation fault-combination sandbody control pattern and parallel synthetic fault transfer zone sand-body control pattern.
