地震屬性優化方法綜述
印興耀,周靜毅
　　隨著提取地震屬性技術的不斷發展,地震屬性種類也在不斷地增加。鑒于地震屬性與所預測對象之間的關系復雜,不同工區和不同儲層對所預測對象敏感的(或最有效的、最具代表性的)地震屬性是不完全相同的,因此必須對地震屬性進行優化處理。通常優化處理是指利用人的經驗或數學方法,優選出對所求解問題最敏感(或最有效、最有代表性)的屬性個數最少的地震屬性組合。筆者認為地震屬性優化主要包括屬性預處理和屬性選擇兩部分。文中分別對這兩部分包含的內容進行了評述,以供從事地震屬性優化的研究人員參考。

　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.
