| 摘 要： | 波动方程偏移保持了波场动力学特征，依此本文应用共方位角叠前深度偏移技术来实现二维资料三维化处理.本方法能使共反射点偏移成像与叠前数据插值一步完成，较好地解决二维资料处理中的成像点不能准确归位、侧面反射波难处理、主测线与联络线不闭合等问题.

| Abstract: | Wave equation migration can preserve the kinetic characteristics of wave field, so this paper applies common-azimuth prestack depth migration technology to realize 3D process for 2D seismic data. This method can make the CRP depth imaging and the interpolation of prestack data be completed simultaneously ,and also it better resolve the problems of 2D data process such as incorrect imaging, difficulty of slde-wave process,disclosure between inlines and crosslines. |

| Keywords: | wave equation double square root operator common-azimuth prestaek depth migration |
