摘　　要：针对在苏北探区变观设计及不同震源联合施工填补城区三维地震采集空白中存在的三维地震数据采集分布不均匀、资料信噪比低等问题,开展了三维地震数据规则化处理方法研究,应用实际数据对三种常用的叠前规则化方法FLEX、FIRE3D、COMFI进行了精细的测试分析,建立了适合城区三维地震资料的规则化处理流程,实际应用效果表明该流程是有效的。Aiming at problems of uneven distribution of seismic data and low signal/noise ratio and so on, which are existed in urban 3D seismic data acquisition, a regularization processing method of 3D seismic data was studied. Actual da- ta were used to carry out more accurate tests and analyses for three usual pre - stack regularization methods of FLEX, FIRE3D ,COMFI, and a regularization processing flow was set up which is suitable for the 3D seismic data in urban area. Application results show that the processing flow is suitable for the 3D seismic data in urban area.
