三分量地震的价值正被人们所认同, 现在正向三维三分量方向发展。本文较系统地介绍了斜三分量三维地震处理技术, 从坐标旋转变换、方位角校正到偏振分析、分裂快慢横波的分离以及各种岩性、物性参数提取, 总结出斜三分量三维地震处理的原则和处理流程。对东北H地区一块斜三分量三维地震资料进行了处理, 取得了成功。

The value of three-component (3-C) seismics has been recognized by people and now it is developing towards the 3-D and 3-C seismics. In this paper we systematically introduce the oblique 3-C and 3-D seismic processing techniques. The principle and the process for the technique have been summarized through coordinate rotation transform, azimuth correction, polarization analysis, separation of split quick and slow shear waves, and extraction of various lithological and physical parameters. A block of oblique 3-C and 3-D seismic data in H area of northeastern China has been prooessed and a success is achieved.
