地震属性优化方法综述
印兴耀,周静毅
随着提取地震属性技术的不断发展,地震属性种类也在不断地增加。鉴于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(或最有效的、最具代表性的)地震属性是不完全相同的,因此必须对地震属性进行优化处理。通常优化处理是指利用人的经验或数学方法,优选出对所求解问题最敏感(或最有效、最有代表性)的属性个数最少的地震属性组合。笔者认为地震属性优化主要包括属性预处理和属性选择两部分。文中分别对这两部分包含的内容进行了评述,以供从事地震属性优化的研究人员参考。

Along with the constant development of detecting seismic attributes techniques, the kinds of seismic attributes also increase continuously. In view of complex relationship between predicted targets and seismic attributes, the seismic attributes sensitive to (or most effective on,or most representative of) targets predicted are not completely identical in different work areas and different reservoirs. For that reason, it has to optimize the seismic attributes. Generally, the optimized processing means that using human experiences and mathematic algorithm to optimize the fewest numbers of composition of seismic attributes characterized by most sensitive to (or most effective on, or most representative of) solved problems. The authors considered that the optimum of seismic attributes should mainly include two parts: preprocessing of attributes and selection of at- tributes. The paper appreciated these two parts of contents separately , which gave a reference to the researchers who engaged in optimum of seismic attributes.
