摘要
归一化层速度是对任意深度处的层速度进行归一化处理的一种速度形式。归一化处理的目的是把任意深度处的层速度转换为与深度无关的格式。归一化后层速度的横向变化主要取决于地层岩性、孔隙度等物性的变化,利用这一特点可以方便地利用已知钻井资料对其进行标定,比较简单地进行地层岩性、孔隙度等物性的预测。实际应用表明,其预测结果与钻井揭示吻合较好,预测效果令人满意。
Normalized interval velocity is a velocity method that is used to normalize interval velocity at any depth, the purpose of the normalization is that interval velocity at any depth will be transformed into a velocity which is not related with depth. The lateral changes of the normalized interval velocity mainly depend on lithology, porosity and some other physical properties. Therefore, normalized interval velocity can be easily compared with drilling data and thus can be used to predict reservoir properties such as lithology, porosity and so on. The result shows that the predicted results are in good relationship with drilling data.
