基于对和声搜索优化算法(HSO)特点及其优越性的分析,将其应用于埃及苏伊士湾a.a.油田Ka.eem油藏油藏工程辅助历史拟合中。HSO算法具有如下优越性:对解空间探索和开发能力之间的良好平衡使得算法具有鲁棒性和高效性;生成解的多样性由两个组件有效控制,更适用于油藏工程历史拟合这样的高度非线性问题;和声记忆库取值、微调和随机化3个组件之间的配合有助于找到无偏性解;算法实现过程简单。将HSO算法与油藏工程辅助历史拟合中2种常用的优化技术(遗传算法和粒子群算法)应用于3个不同复杂程度的油藏工程历史拟合问题——2个不同尺度的物质平衡历史拟合和1个油藏历史拟合,通过对比3种算法拟合效果验证了HSO算法的正确性和优越性。Ka.eem油藏历史拟合结果表明,在辅助历史拟合工作流中采用HSO算法作为优化方法可以显著提高拟合质量,缩短求解时间。
