摘要

地震属性是由地震数据衍生出的几何形态、运动学、动力学以及统计特征的特别量度。根据地震属性与岩层物性的统计关系推断地下岩层物性和油气分布的技术称为地震属性反演。本文简单介绍了地震属性的分类及井震结合地震属性反演方法的基本原理,并在苏里格气田进行了实际应用。该方法充分利用了钻井资料纵向精细、横向稀疏,地震资料纵向粗略、横向密集的特点,更精确地刻画砂体,针对苏里格气田二叠系储层非均质性强,砂体横向追踪困难的特点,取得满意效果。
Seismic attribute is the special measurement of the geometry,kinematics,kinetics and statistical property derived from seismic data.The technology which is used to infer underground formation physical property parameters and oilgas distribution is called as seismic attribute inversion according to the statistical relationship between the seismic attribute and the formation physical property.In this paper,the basic principle of seismic attribute inversion method and the classification of the seismic attribute are introduced,and it is applied in the Sulige gas field to predict reservoir.The method makes full use of unique feature which the drilling data is fine in vertical and the seismic data in horizontal to more finely describe sand body.In view of the feature of Sulige gas field,satisfied results are achieved.
