利用波阻抗数据体进行了砂岩厚度和有效砂岩厚度预测，预测结果与钻井结果吻合较好。
The impedance data volume was used to predict the sand thickness and the effective sand thickness, showing a good accordance with the drilling results.
由于榴辉岩与其他岩石类型之间存在较大的波阻抗差异，因此用零偏VSP资料标定该区地震波的地质层位是有效的。
Since large impedance contrasts exist between eclogite and other rocks, it is effective that the VSP profiles are used to calibrate geological horizons of seismic reflections.
