摘要
通过对NB油田三维地震资料的精细解释,重新落实了该构造下降盘的构造特征,并对该区块的沉积和储层特征进行了重点分析,利用地震反射特征分析和属性提取等技术手段对有利储层进行预测。油田断下盘侏罗系油气藏主要受构造控制,而白垩系油气藏主要受岩性控制。通过对下降盘油气藏特征的重新认识和评价,为NB油田外围的滚动勘探提供了有利依据,在实际生产上也取得了非常好的效果,对盆地内其它油田的勘探开发也起到了重要指导作用。
Based on detailed interpretation of 3D seismic data in NB oilfield, this paper confirm the structural teatures of the falling block of this oilfield, analyzes sedimentai7 and reservoir characteris- tics as a key point, predicts the useful reservoir by seismic reflection teature and attribute extractive and other technological means. The Jurassic reservoirs were controlled by the structure primarily, and the Cretaceous reservoirs were controlled by lithology primarily in NB oilfield. Through the re- petitive understanding and evaluation of the characteristics of the falling block reservoirs, the paper provides a favorable basis for rolling exploration of NB oilfield. A good result has been achieved in actual production. This method also plays an important guiding role in guiding exploration and devel- opment of other oilfields in the same basin.
