横波速度是地震勘探中的重要参数。本文总结了常用横波速度的预测方法,然后选用了我国东部某油田10口井的实际纵横波速度资料来预测目标井的横波速度,采用目前广泛应用的Castagna经验公式通过最小二乘法进行线性回归拟合出纵横波经验公式,从而达到预测横波速度的目的。
S-wave velocity is an important parameter in seismic exploration. This paper summarizes the commonly used methods for the prediction of shear wave velocity and then selects the actual P- and S-wave velocity data of 10 wells in an oilfield in eastern China to predict the shear velocity of the target well. The least square method is used to perform the linear regression simulation using the widely used Castagna empirical formula The empirical formulas of longitudinal and transverse waves are combined to achieve the purpose of predicting the transverse wave velocity.
