摘　　要：提取相关的地震属性,对这些地震属性进行聚类研究及分析归纳,找出针对储集体的敏感属性,建立起储集层的地震响应模式。这里对几种重要参数的计算原理、物理特性进行了分析,并做了正演模型研究,对川东北部地区飞仙关组鲕滩储层进行了参数提取与过井参数聚类。结果表明,对高品质的地震资料,使用属性分析进行储层的模式建立以及储层的横向变化研究是可行的。The paper introduces the methods for extracting horizon seismic a ttributes and performing cluster study as well as the analysis of thes e attributes to find out the sensitive attributes to reservoirs. Based upon them, seismic response patterns of reservoirs are built. Then author s analyze the estimation principle and physical properties of several imp ortant parameters , and perform forward modeling study , and extraction and cluster analysis of parameters across wells for oolitic beach res ervoirs of Feixianguan formation in Northeastern Sichuan . The study r esults reveal that it is plausible to build reservoir patterns and stu dy reservoir lateral variation using the method with high quality seismic data.
