港东开发区明化镇组和馆陶组属于河流相沉积，应用高分辨率层序地层对比技术在明化镇组和馆陶组砂体细分小层的基础上，以三维地震资料为基础，通过精细层位标定确定储层砂体的地震响应特征，遵循层序对比的原则加密解释到小层，利用先进的分频处理解释技术和三维可视化技术，追踪河道砂体的分布范围。运用以点带面和以面促点的研究方法，对研究成果与实际钻井开展匹配分析。通过实际应用，取得了明显地质效果，为河道追踪预测技术提供了新的研究方法和手段。

The Minghuazhen Formation and Guantao Formation of Gangdong exploitation area are fluvial facies deposits. Based on 3-D seismic data and fine\|division layers of the Formations by high-resolution sequence technique, the seismic response characteristics of reservoir sand layers are defined. Sub-layers are interpreted according to the sequence-contrasting law. The distribution range of channels is traced using the advanced spectrum decomposition processing-interpretation technique and 3-D vision technique. The results of calculation and real drilling data are matched well by using the methods of point-controlling-surface and surface-directing-point. The practical geological effects are very satisfactory.
