Abstract

Abstract

The shear wave velocity of well log is an important parameter for mutual inversion, but lots of wells are short of this value.As present estimation method can't calculate the shear velocity precisely, based on rock physics, using VRH model this paper firstly calculates the equivalent elastic modulus via multi-mineral analysis from routine well logs, and then by taking compressional velocity as a constraint, calculates the shear wave velocity based on Biot-Gassmann equations.The method has clearer physics meaning, and practice results show that this method is much more convenient, economic and precise than Xu-White methods, and the error between computational value and measured value is less than 5 percent.
