从合成地震记录的原理及制作方法入手,对反射系数序列和子波两个基本要素进行分析,提出了三种提高合成记录制作精度的方法:密度和声波曲线联合使用;提取实际子波;利用多种速度资料进行时深转换。探讨了在制作合成记录过程中如何提高制作精度,并提出使用相关系数法、曲线对比法以及剩余记录法等来衡量合成记录制作的质量。
Starting with the principle and method of synthetic seismogram, two basic elements of reflection coefficient sequence and wavelet are analyzed, and three methods to improve the accuracy of synthetic recording are proposed: the combination of density and acoustic wave curve; the extraction of actual wavelet; Time-velocity data conversion. This paper discusses how to improve the production precision in the process of making composite record, and proposes to use the correlation coefficient method, curve comparison method and residual record method to measure the quality of composite record production.
