详细分析了地震属性组合优化的搜索算法,讨论了地震属性的组合分类特征及地震属性数值大小对分类特征的影响。在此基础上,研究了联合应用搜索算法和进化算法,对地震属性和测井参数进行优化的新方法,并应用于实际资料,取得了较好的效果。

This paper discusses in detail the search algorithm for the optimal combination of seismic attributes, and analyzes the characters of seismic attribute combination as well as the effect of the quantity of each seismic attribute to the combination. A new method for the optimization of seismic attributes and logging parameters is developed by combining search algorithm and evolution algorithm. Desired results have been achieved by applying the new method to real data.
