摘要：

大庆油田葡萄花油层一油组砂岩储层注水地震监测正演模拟分析结果表明:不同的油藏对监测地震资料的视觉信噪比与视觉分辨率的要求是不同的,对于相同的岩石物性变化,薄层或薄互层对地震资料视觉分辨率与视觉信噪比的要求要比厚储层高得多;要监测薄互层内各小层中流体动态的变化,必须提高差异地震剖面的分辨率与视觉信噪比,差异地震剖面的视觉信噪比与视觉分辨率的乘积可作为时移地震监测可行性定量分析的良好指标.

Abstract:

The forward modeling result of waterflood seismic monitoring of Pu 1 group sandstone reservoir in Daqing Oilfields shows that different reservoirs have different demands for visual resolution and visual signal to noise ratio of seismic data used in reservoir monitoring.Comparing with thick reservoirs of the same lithological property,thin reservoirs and thin interbedded reservoirs demand higher visual resolution and visual signal to noise ratio.Monitoring fluid performance variation of each bed in thin interbedded reservoirs must improve the resolution and the visual S/N ratio of different seismic profile.The product of the visual resolution an isual S/N ratio can be used in the feasible quantitative analysis of time lapse seismonitoring.

Key words: reservoir characteristics, time lapse seism, forward modeling, visual resolution, visual signal to noise ratio, Daqing Oilfield
