摘　　要：为了实现在深度域制作合成地震记录及在深度剖面上进行层位标定 ,开发了深度域合成记录制作及层位标定软件系统。将时间域的子波转换成深度域的子波 ,再与反射系数进行褶积 ,就可得到深度域的合成地震记录。然后 ,将深度域合成地震记录插入到深度剖面中 。Compared with time section,seismic depth-migration section has characteristics of interpreting underground structures truly,intuitively and conveniently. But how to make synthetic seismogram and horizon calibration in depth domain is an important and urgent-solving problem.In time domain,the conbolution of wavelet and reflective coefficient determines synthetic seismogram which is similar to that in depth domain. But the depth domain seismogram only needs to tranform wavelet from time to depth,and the convolution of wavelet and reflective coefficient in depth domain is the synthetic seismogram of depth,which is inserted in depth section to calibrate horizons accurately. The satisfactory effect is achieved by applying the software system into Xushen1 and Huodemoer projects in Northern Songliao Basin.
