针对多信息储层预测,介绍了QuincyChen等人基于储层特征的地震属性分类,讨论了地震时窗的选取和属性预处理方法,提出了地震属性有效性分析基本准则和工作程序,并对优选地震属性的主要算法进行了介绍,结合大庆宋芳屯油田芳深 2区块储层预测给出了一个应用实例。

Based on the seismic attribute classification proposed by Quincy Chen and others for reservoir characteristics, this paper discusses the methods of seismic time window selection and attribute pretreatment. The criteria and procedure of seismic attribute effectiveness analysis and algorithms of seismic attribute optimization are presented. An example of reservoir prediction in Block Fangshen2 of Songfangtun Oilfield in Daqing is also presented in the paper. The author believes that extraction and effectiveness analysis of seismic attribute is the prerequisite for high-precise seismic reservoir prediction, therefore much attention should be devoted.
