摘要
本文针对合成地震记录制作和使用中存在的问题,系统地分析了合成地震记录和地震剖面的相关性因素,指出从声波测井曲线和褶积模型两方面改进合成地震记录的质量。文中以实例说明合成地震记录的使用陷井,并提出识别陷井的平均速度分析法和层序波形对比法。为更细致地进行反射波分析,文中还介绍了合成地震记录的波形分析方法。
In view of the problems encountered in synthesizing seismograms and their application, this paper systematically analyzes the factors which are in control of the resemblance between synthetic seismograms and field data and suggests to improve synthetic seismograms' quality using sonic log and convolution models. The paper also demonstrates the 'traps ' in using synthetic seismograms with real data examples and advocates to identify them via average velocity analysis and waveform correlation for seismic sequence. To study reflection waves more in detail,the waveform analysis on synthetic seismograms is furtheir introduced.
