| 摘 要： | 冀中油田南孟潜山断裂构造复杂，以往所采用的时间偏移方法的地震成像精度不高。本文应用三维叠前深度偏移方法对南孟潜山地震资料进行了重新处理，处理流程包括：常规三维处理、建立时间域地质模型、精细速度分析及建立速度场、最终偏移成像、修饰等。根据重新处理的叠前深度偏移资料，落实了府君山、长龙山、雾迷山构造，并在长龙山组砂岩油藏中获得高产商业油流。

| Abstract: | Nanmeng buried hill fault structures of Jizhong Oilfield are complex,the seismic imaging of former adopted time migration method has poor resolution.The paper applied the 3 D pre stack depth migration to re process the seismic data of Nanmeng buried hill,the processing flow included ordinary 3 D seismic processing,build up of geologic model in time domain,subtle velocity analysis,build up of velocity field,final migration imaging and post migration processing.According to re processed pre stack depth migration data of the structures.Fujun mountain,Changlong mountain and Wumi mountain are defined.The industrial oil flow with high production has been found inGroup sandstone reservoirof of Changlong mountain. |
