| 摘 要： | 基于已有的河流相砂体发育模式,本文应用相控正演模拟法对大井距条件下秦皇岛32-6油田北区(NmⅡ-4小层)河流相砂体(的叠置关系)进行了精细描述。在此过程中,明确了河流相砂体可识别条件,建立了单河道砂体边界识别标志正演概念模型,总结了单河道砂体边界识别标志正演响应波形特征,最终识别出单河道和单一点砂坝边界。研究结果表明:在该区目的层段地震波主频近60Hz条件下,应用相控正演模拟法能在较大井距间时准确识别出单河道和单一点砂坝边界,提高了大井距条件下河流相砂体构型分析精度。

| 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. |
