地震属性与所预测对象之间的关系复杂,不同工区和不同储层对所预测对象敏感的地震属性是不完全相同的,即使在同一工区、同一储层,预测对象不同,对应的敏感地震属性也是有差异的,地震属性优化技术是解决此问题的有效途径。运用降维映射、属性选择和聚类、交会分析等地震属性优化方法,优化了预测储层的地震属性,同时结合实钻资料,结合地震属性运用地质统计学进行定量分析,对优选出的地震属性进行验证,可以有效地消除地震方法划分曲流河沉积微相的多解性。
The relationship between seismic attributes and the predicted objects is complex. The seismic attributes that are sensitive to the predicted objects in different work areas and different reservoirs are not identical. Even in the same work area, the same reservoir and the different objects to be predicted, the corresponding sensitive seismic attributes There are also differences, seismic attribute optimization technology is an effective way to solve this problem. By using seismic attribute optimization methods such as dimensionality reduction mapping, attribute selection and clustering, intersection analysis and other seismic attribute optimization methods, the seismic attributes of the reservoir are optimized. Combined with the real drilling data and the seismic attributes, the geostatistics is used for quantitative analysis. Attribute validation, can effectively eliminate the seismic method to divide the meandering river sedimentary microfacies multi-solution.
