Abstract：Based on the existing fluvial facies sand body development pattern,this article describes finely the superimposed pattern of fluvial sand bodies in the North Block of the Qinhuangdao 32-6Oilfield with phase-controlled forward modeling.First, fluvial reservoir characterization conditions are determined.Then the forward modeling for single channel boundary identification is established,and waveform characteristics of single channel boundary identification are summarized.Finally,the boundaries of single channel and a single point bar are identified.The results show that the boundaries of single channel and single point bar can be accurately recognized on seismic data with the dominant frequency of 60Hz by the phase-controlled forward modeling method.
