| 摘 要： | 本文采用逆时递推,在空间域完成纵横波分离,同时实现了位移场成像和纵、横波的独立成像。模拟数据与实际资料试算表明,对纵波和横波分别成像不仅有理论意义,而且有明显的应用价值。文中还就偏移速度对成像结果的影响和实际资料的预处理问题进行了讨论。

| Abstract: | In this paper,the longitudinal and transverse waves are separated in the process of reverse time migration in space field,and then the two waves are imaged separately at the same time as the displacement field are imaged.A few models and real data tests show that this new imagery method,longitudinal and transverse waves imaged separately,has not only theoretical significance but also applicational value.Besides,the effect of migration velocity on imagery depth and preprocess of real data are discussed. |
