摘　　要：在利用地震属性对储层预测的研究中,大部分理论方法主要存在利用单一属性预测储层这一缺陷,在实际应用中则存在单一属性不能正确预测储层的问题,这些问题应通过多元属性融合技术来解决.本文在已有井资料的基础上,对属性融合技术进行了研究,分析各属性对储层的影响因素.利用井位计算各地震属性融合比重,有机的结合了各属性的优点,提出了这一问题新的解决方法.实际资料的应用显示,该方法在储层预测中取得了良好的效果.In research on using seismic attributes to reservoir forecast,most of theories and means present default of using singlet attribute to forecast reservoir.In application,the problem is that singlet attribute can not forecast reservoir correctly.These questions should be resolved by technique of multiple attributes synthesis.This article makes a research on the technique of attributes synthesis,which is based on well data;analyzing the factors that each of attributes has influence on the reservoir.In order to propose a new solution to this question,we use well data to compute each of seismic attributes synthesis weight,and unite the merits of each attribute.Actual application shows that this methed has made good results in the reservoir forecasting.
