摘　　要：本文在简单介绍转换波基本概念的基础上,以胜利油田永新地区实际采集的转换波资料为对象,开展了转换波叠前数据净化、转换波静校正、纵横波速度比扫描等处理方法的研究,较好地压制了该区转换波资料的面波干扰,求出了较精确的转换波静校正量和速度,并通过叠前时间偏移实现了真正的共转换点叠加。On the basis of briefly introducing basic conception of converted wave and taking C-wave data practically acquired in Yongxing area as object, the paper carried out the study on such processing method as C-wave data purification, C-wave static corrections, sweeping of P-wave-to-S-wave velocity ratio, and better suppressed plane wave interference of C-wave in the area, acquired more precious C-wave statics and velocity and realized CCP (common converted point) stack by prestack time migration.

关 键 词：转换波 共转换点 纵横波速度比 转换波静校正
