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。
Based on the 3D seismic data and other data, the faults developed during the transition from fault depression to depression in the third member of Dongying Formation in Paxian Sag are deeply studied to identify the fault development patterns and to summarize the paleogeomorphic features formed by fault control. Combining with the core, single well and geochemical data, Analyze the controlling role of palaeogeomorphology in the development of fault control on the spatial distribution of sedimentary facies and sand bodies and summarize the control mode. The results show that there are mainly three types of sand control modes during the sedimentary period of the East Third Member: the sand control model of the broom-like sedimentary fault, the sand control mode of the echelon-type fault combination and the sand control mode of the parallel syn-fault transition zone.
