【摘要】 从古地貌、沉积相带和地震属性间的关系出发,论证了古地貌背景约束下地震属性优选技术的合理性。阐述了多属性聚类分析技术,将优选出的敏感地震属性进行聚类分析,并将其应用于礁滩相储集层和油气预测中。应用实例表明,基于古地貌背景约束优选出的地震属性和相应的多属性聚类方法,能有效表征生物礁储集层发育的有利相带、物性特征及部分流体特性。更多还原

【Abstract】 In view of relations between paleogeomorphology,sedimentary facies and seismic attributes,this paper presents multi-attribute cluster analysis method and demonstrates its rationality under constraining condition of paleogeomorphology.The optimized seismic attributes followed by cluster analysis can be applied to prediction of reef reservoir and fluid property.The case study from Sichuan basin shows that such a multi-attribute cluster analysis method can effectively characterize the favorable facies,physical peature and partial fluid characteristics of reef reservoir.更多还原
