Xu-White模型预测横波速度的不确定因素分析

自Xu和White (1995)建立了泥质砂岩的有效介质模型(Xu-White模型)后,很多地球物理学者用此模型或改进的模型进行岩石横波速度的预测,但至今很少有人对Xu-White模型预测过程中的不确定因素进行详细总结。介绍了Xu-White模型及其预测流程;对预测过程中的不确定因素进行了分析,指出在使用中可以根据实际地质情况合理的取舍参数,从而能更有效地进行纵横波速度预测。

Uncertainty of shear wave velocity prediction by Xu-White model

Since Xu and White established the effective medium model about sand-clay rock (Xu-White model) in 1995, many geophysicists have predicted shear velocity by this model and its improved model. But few of them have made detailed review of the uncertain factors in the process, this paper firstly introduced the Xu-White model and its prediction flowchart, and then made a detailed analysis on the uncertain factors in the process of prediction, which can make researchers choose more reasonable parameters to predict more effectively shear velocity according to the actual geological conditions.
