摘　　要：为了克服地震属性预测结果不确定性问题,设计了地震属性融合定量储层预测实验。从储层特征分析入手,采用地震正演模拟确定反应储层特征的敏感地震属性,以单属性和砂岩厚度相关度完成属性优选,通过属性加权融合处理,最终实现定量储层预测。实验结果表明,基于储层特征地震正演分析的属性加权融合方法,对储层的预测精度明显提高。该实验设计加深了学生对勘查技术与工程专业知识的理解,有助于提升他们的工程实践能力。In order to overcome the uncertainty of seismic attribute prediction results,a quantitative reservoir prediction experiment based on seismic attribute fusion is designed.Starting with the analysis of reservoir characteristics,the sensitive seismic attributes reflecting reservoir characteristics are determined by seismic forward modeling,the attribute optimization is completed by single attribute and sandstone thickness correlation analysis,and the quantitative reservoir prediction is finally realized through attribute weighted fusion processing.The experimental results show that the attribute weighted fusion method based on seismic forward modeling analysis of reservoir characteristics can significantly improve the accuracy of reservoir prediction.The experimental design deepens students’understanding of exploration technology and engineering expertise,and helps to improve their engineering practice ability.
