摘　　要：安哥拉海上B油田属于超深水油田,储层为中孔、高渗、深水浊积砂岩,是中轻质的边底水油藏,目前采出程度为20%,含水率约40%。应用四维地震振幅差异属性技术和四维地震有色反演波阻抗技术开展油藏开发动态研究,能够监测油藏的原始油水界面、油气界面的驱动前缘和注入井的水驱前缘,进而研究油藏内部的连通性及剩余油分布情况。四维地震油藏监测,不仅优化了加密井井位,而且细化了油藏动态模型,进一步提升了油藏精细化管理水平。Oilfield B in Angola offshore is an ultra-deep-water oil reservoirs, which are composed of medium-porosity, high-permeability and deep-water turbidite sandstones, including medium-light edge-bottom oil pools. The current produced recovery factor is 20% and watercut is about 40%. By 4D seismic amplitude-differing and 4D seismic impedance colored inverting techniques, the performances of the oil reservoir production are researched, thus the original water oil contact, driven front of the gas oil contact and waterflooded front of the water injectors can be monitored, and moreover the connectivity within the oil reservoirs and remained oil distribution can be further made clear and studied. By means of the 4D seismic supervision, the filled well location has been optimized ; the dynamic model of the reservoirs has been improved and refined, so the fine reservoir management can be realized finally.
