摘要
In this paper,based on classic Xu-White model,the improved Xu-White model for carbonate rocks is constructed from rock physics theory.Then through an analogy study of empirical equations for carbonate rocks built by Pickett,Castagna and so on,the empirical relations for the practical carbonate zones.Finally the empirical equations and the improved Xu-White model are used to calculate shear velocity for the practical carbonate zone.The estimated results illustrate that higher predicted accuracy of shear velocity can be obtained by the improved Xu-White model.
