摘要
利用Gassmann等效介质理论定量分析了岩石物性参数和地震动力学参数之间的关系。结合部分岩石物理等效理论及经验公式,探讨Gassmann方程的3种流体替换流程。利用替换后目的层等效参数,能够为正演模拟替换层波场特征、实现由已知预测未知和岩性预测及气水识别提供资料。
By using the Gassmann equivalent medium theory,the relationship between rock properties and seismic kinetic parameters.At the same time,in combination with the physical equivalent of rock and empirical formula,was quatantitatively analyzed the three substitution forms of Gassmann equation were discussed.Using the the equivalent parameters of purpose layer,the wave-field characteristics of the replacement layer,prediction from the known to unknown,for lithology prediction and identification gas-water were simulated to provide information.
