摘　　要：作者根据中国石油集团公司颁布的地震资料处理规范,并结合国际通常做法,从几个质量控制基本环节分析了现行质量控制体系存在的问题,并就预处理、初至拾取和折射静校正、叠前去噪、反褶积、速度分析、叠前时间偏移等处理环节提出了改进方案,设计了质量控制点和基本控制图件,强调了地震资料处理过程监督的重要性。通过对实际地震资料处理项目的运作,获得了较好的效果。According to the standard of seismic data processing issued by CNPC and combining with the international usual practice, the authors analyzed the existed problems in current QC system from several basic QC links and presented improving schemes from the following processing links considering preprocessing, first breaks pickup and refraction static correction, prestack denoise, deconvolution, velocity analysis and prestack time migration, and designed QC points and basic controlling charts, emphasizing the importance of QC in seismic data processing. It has been achieved good results through the operation of practical seismic data processing project.
