摘　　要：地震相分类技术已被广泛地应用于沉积相识别及储层预测中,现在流行的商业软件Stratimagic提供了基于地震道、平面图和地震数据体的道、面、体三种地震相分类划相技术。这里从原理、方法流程及应用效果等方面,对这三种分类划相技术的特点和作用进行了总结和对比,提出了这三种分类划相技术的适用范围和使用原则。并将此方法应用到我国西部BKQ地区的储层预测研究中,划分出了研究区的有利储集相带,为后期的钻井部署提供了有利的依据。Seismic facies classification techniques have been widely used in the sedimentary facies identification and reservoir prediction.Now the popular commercial software Stratimagic provides trace,map and block seismic facies classification technology which is based on the seismic trace,map and seismic blocks.In this paper three kinds of classification of seismic facies analysis techniques are summarized and compared,which is done from principals,workflow,application effects and so on.And the scope and guidelines of the three classification techniques are provided in the paper.The proposed approaches have been applied to reservoir prediction in the regions of western China BKQ.The results give the favorable reservoir facies and provide the favorable basis for the drilling sets deployment.
