Moreover, a model of Generalized Elastic Impedance established on this base suiting the routine post-stack, non-zero offset seismic data was put forward by us. Generalized Elastic Impedance which does not only include acoustic impedance but also include lithologic information of P and S-wave velocity. 在此基础上建立的适合常规叠后资料的、非零炮检距纵波资料的广义弹性阻抗(generalizedelasticimpedance)模型不仅包含波阻抗,还包含了纵横波速度等岩性信息。
