| 摘 要： | 渤海BZ28-1油田为裂缝性潜山油气藏.该区原三维地震资料分辨率低、信噪比低,很难满足裂缝储层预测的要求.为了研究该区裂缝的分布,设计了由8条二维测线组成的多方位地震测网,首次进行了多方位地震采集,并对新采集的数据进行了高分辨率处理和完全保幅处理.利用方位NMO速度、方位时差、方位AVO等地震属性的变化,对BZ28-1油田裂缝发育状况及分布进行了预测,取得了较好的效果.

| Abstract: | BZ28-1 is an oilfield with fractured buried-hill reservoirs in Bohai sea,where existed 3D seismic data failed to predict the fractured reservoirs because of their low resolution and low signal-to-noise ratio.In order to probe into the fracture distribution in this field,multi-azimuth seismic data have been firstly acquired by designing a multi-azimuth seismic network composed of 8 2D lines,and have been processed for high resolution and complete amplitude preservation.Using the variations of seismic attribu... |
