| 宽线地震采集原始数据相比二维数据具有更丰富的信息，为充分挖掘宽线数据本身的优势和潜力，提升宽线数据处理效果，本文根据宽线数据和二维及三维数据的异同，借鉴了目前“两宽一高”三维地震数据处理流程，主要研究了宽线有源噪音压制及浅海拖缆宽线大羽角数据共中心点离散处理技术，提出了观测系统定义方式需要根据不同处理模块的要求进行实时变换的建议，总结完善了针对复杂区宽线处理技术策略，提升了宽线的处理成果剖面质量。为复杂区宽线地震资料处理总结了一些经验。 |

| Wide-line seismic raw data contain more abundant information than two-dimensional data. In order to fully exploit the advantages and potentiality of wide-line data and improve the wide-line data processing effect, this paper examines the similarities and differences between wide-line data and three-dimensional data. In light of "WGH" three-dimensional seismic data processing technology, we study the wide-line interference noise suppression and the common middle points discrete processing technology of the large feather angle data of shallow sea tow cables. We suggest that the definition of the observation system needs real-time transformation according to the requirements of different processing modules. Finally we summarize and improve the processing technology strategy of wide-line in complex areas, and enhance the quality of the wide-line processing results. Some experiences are presented for processing wide-line seismic data in complex areas. |
