地震属性分析是储层描述的一项重要技术手段。目前地震属性分析技术发展迅速,在油气田开发中得到广泛应用,并起到越来越重要的作用。本文系统总结了储层预测技术在大港油田歧口凹陷的应用效果,明确了对复杂储层分布区应用波形相似度、均方根振幅、平均瞬时频率、平均瞬时相位等地震属性分析的地球物理新技术,是进行精细储层预测与砂体识别的有效手段。 Seismic attribute analysis is an important technical means of reservoir description. At present, the seismic attribute analysis technology is developing rapidly and has been widely used in the development of oil and gas fields and plays an increasingly important role. This paper systematically summarizes the application of reservoir prediction technology in the Qikou depression of Dagang Oilfield, and clarifies the application of the geophysical analysis of seismic attributes such as waveform similarity, root mean square amplitude, average instantaneous frequency and average instantaneous phase to the distribution of complex reservoirs The new technology is an effective method for fine reservoir prediction and sandbody identification.
