【摘要】 地震属性研究中时窗的选取是影响储层预测精度的关键之一。文章通过埕岛东部地区的基本地质特征进行分析,提出了地震属性研究中时窗的选取方法。首先通过地质认识宏观判定储层展布特点,选取大尺度的研究时窗。其次在主要目的层段内进行砂层组划分研究,选取包含相邻地震同向轴的研究时窗,最后结合层拉平、三维浏览切片进行落实。对不同的工区根据实际的地质情况选取合理的分析时窗会更为可靠。更多还原

【Abstract】 The window selection is the key for seismic attributes accuracy in reservoir prediction.In this paper,the method selecting seismic attributes time window is developed through analyzing the eastern part of Chengdao basic geological characteristics.First,the reservoir distribution is determined by understanding the macro geological exhibition to select a large-scale study window.Second,the sand layer is divided within the segment research groups,including selected the adjacent axis of the seismic phases.Finally it is determined combining with the horizon flatten and three-dimensional slice.The reasonable analysis window will be more reliable according to actual geological conditions for different area.更多还原
