摘要
将地震属性技术引入到对井间地震资料的分析与应用。井间地震资料以深度域表示,在地震属性提取过程中,主要考虑幅度、波形和相关函数等特征量参数,提取了信噪比等18种与井间地震深度域相关的属性参数,并采用极差正规化标准对地震属性参数进行归一化处理,用R型聚合法聚类分析方法对所提取的18种属性进行聚类,优选出3组属性。通过对胜利油区垦71井区井间地震资料的属性分析与应用研究,总结出砂泥岩薄互层的最优化地震属性,为井间地震资料解释提供了新的思路和方法。
Cross-well seismic data are expressed as depth domain and 18 attributes associated with depth domain of cross-well seismic data such as S/N ratio have been abstracted mainly taking such characteristic parameters as amplitude, waveform and correlate function, ect. into account. The attributes are normalized with respect to range normalization criterion. Three groups of attributes have been optimally selected from these 18 attributes after being analyzed by R clustering method. The optimized cross-well seismic attributes for thin inter-beds of shale and sandstone have been determined through cross-well seismic data from Ken 71 well-block of Shengli Oilfield.
