摘　　要：通过对陡倾角构造模型的地震采集正演模拟分析,论证陡倾角地层成像效果与采集方向的关系,通过对海上拖缆双船双边同步激发的采集观测系统的研究,设计了拖缆双船双边激发的施工方案和施工参数,在特定靶区进行拖缆双船双边激发的地震资料采集和处理试验,根据地震数据的处理成果对比分析,总结拖缆双船双边激发的采集效果、对陡倾角构造成像的作用及采集施工的效率及可行性,为今后海上多船采集施工提供参考依据。Based on the analysis of seismic acquisition forward model for the steep dip struc-ture, the relationship between image results and acquisition direction in steep dip strata is proved. By the study of acquisition observation system of bilateral synchronous excitation for double marine streamer boats, the construction scheme and parameters of bilateral exci-tation of double streamer boats are designed. The seismic data of bilateral excitation of double streamer boats are acquired and processed in specific target area. According to the a- nalysis and comparison of the processing result of seismic data, this paper sums up the ac-quisition effect of bilateral excitation of double streamer boats, the imaging effect of steep dip structure and the efficiency and feasibility of acquisition construction, which offer refer-ences for the construction of marine multi -ship acquisition in the future.
