摘　　要：基于常规的合成地震记录井-震对比方法,通过合成地震记录分别与各种叠加剖面、CRP道集、角度道集的对比分析,展示了合成地震记录在与不同地震资料对比方面所存在的一些差异。对这些差异性的认识不仅可以提高合成地震记录制作的精度,更有助于对AVO现象的认识和改进异常响应的分析方法。Based on the method of well-seismic comparison of composite seismic traces,through the composite seismic traces,the stacked profile CRP gather,angular gather were comparatively analyzed,by which the differences existed in different seismic data of the composite seismic traces were indicated.The recognition of these differences is beneficial for improving the precision of composite seismic traces and the understanding of AVO and as well as improving the method of the analysis of composite seismic traces.
