摘　　要：受采集方式和环境的影响,海上三维拖缆地震资料采样不规则,覆盖次数不均匀,采用常规的面元均化处理技术容易导致振幅信息误差,最终影响偏移成像效果。提出了基于反漏频傅里叶变换的数据规则化技术处理流程,实现了地震数据规则化,该项技术已经成功应用于南海QH油田地震数据中,有效地改善了数据品质,提高了成像质量。Marine 3D seismic data by tow-cable are usually irregular in sampling and inhomogeneous in coverage due to the impacts of collection mode and environment, and using the traditional approach of bin equalization is easy to result in amplitude error and finally affect imaging quality. A workflow of da ta regularization based on anti-leakage Fourier trans- form was developed, by which the regularization of 3D marine seismic data by tow-cable has been real- ized. This technique was successfully used to process seismic data in QH oilfield, South China Sea. with the data and imaging quality improved effectively.
